# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
InfluxDB MCP Server - A Model Context Protocol server that enables AI assistants to interact with InfluxDB v2 time-series databases. Built with TypeScript, using the MCP SDK, axios for HTTP, and zod for validation.
|
||||
|
||||
## Build and Development Commands
|
||||
|
||||
```bash
|
||||
# Install dependencies
|
||||
npm install
|
||||
|
||||
# Build TypeScript to JavaScript
|
||||
npm run build
|
||||
|
||||
# Watch mode for development (rebuilds on file changes)
|
||||
npm run watch
|
||||
|
||||
# Run the compiled server
|
||||
npm start
|
||||
|
||||
# Run with custom environment variables
|
||||
INFLUX_URL=http://localhost:8086 INFLUX_TOKEN=your_token INFLUX_ORG=your_org node dist/index.js
|
||||
```
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
### Three-Layer Structure
|
||||
|
||||
1. **index.ts** - MCP Server Implementation
|
||||
- Defines MCP resources (read-only URIs like `influx://health`, `influx://buckets`)
|
||||
- Defines MCP tools (actions like `query_flux`, `write_data`, `create_bucket`)
|
||||
- Handles tool execution and resource reading via request handlers
|
||||
- Environment variable validation using Zod schema
|
||||
- Startup health check verifies InfluxDB connection before serving
|
||||
|
||||
2. **influx-client.ts** - InfluxDB REST API Client
|
||||
- Axios-based HTTP client with token authentication
|
||||
- Methods for all InfluxDB v2 API endpoints (query, write, buckets, orgs, tasks, dashboards)
|
||||
- Query response parsing from JSON format
|
||||
- Centralized error formatting via `formatError()` static method
|
||||
- Schema discovery using Flux `schema.measurements()`, `schema.measurementTagKeys()`, `schema.measurementFieldKeys()`
|
||||
|
||||
3. **types.ts** - TypeScript Type Definitions
|
||||
- Complete interfaces for all InfluxDB entities
|
||||
- InfluxConfig, HealthStatus, Organization, Bucket, Task, Dashboard
|
||||
- QueryResult, QueryTable for query responses
|
||||
- BucketSchema, Measurement, FieldInfo for schema discovery
|
||||
- WritePrecision type: 'ns' | 'us' | 'ms' | 's'
|
||||
|
||||
### Communication Flow
|
||||
|
||||
```
|
||||
MCP Client → stdio → InfluxDBMCPServer → InfluxDBClient → InfluxDB REST API
|
||||
```
|
||||
|
||||
The server runs on stdio (stdin/stdout) for MCP protocol communication. All logging goes to stderr to avoid interfering with the protocol.
|
||||
|
||||
## Key Implementation Details
|
||||
|
||||
### Environment Configuration
|
||||
|
||||
Required environment variables validated at startup:
|
||||
- `INFLUX_URL` - InfluxDB server URL (must be valid URL)
|
||||
- `INFLUX_TOKEN` - Authentication token (required)
|
||||
- `INFLUX_ORG` - Organization name (optional, can be provided per-request)
|
||||
|
||||
Configuration is validated using Zod schema in `loadConfig()` function.
|
||||
|
||||
### MCP Resources vs Tools
|
||||
|
||||
**Resources** are read-only URIs that expose InfluxDB state:
|
||||
- `influx://health` - Server health
|
||||
- `influx://buckets` - All buckets
|
||||
- `influx://buckets/{id}` - Specific bucket
|
||||
- `influx://orgs` - All organizations
|
||||
- `influx://tasks` - Scheduled tasks
|
||||
- `influx://dashboards` - Dashboards
|
||||
|
||||
**Tools** are actions that can modify state or query data:
|
||||
- `query_flux` - Execute Flux queries (requires query string, optional org)
|
||||
- `write_data` - Write line protocol data (requires bucket, org, data, optional precision)
|
||||
- `create_bucket` - Create bucket (requires name, org_id, optional retention_seconds, description)
|
||||
- `delete_bucket` - Delete bucket (requires bucket_id)
|
||||
- `list_measurements` - List measurements in bucket (requires bucket, optional start/stop)
|
||||
- `get_bucket_schema` - Get schema info (requires bucket, optional start/stop)
|
||||
|
||||
### Error Handling Pattern
|
||||
|
||||
All errors are centralized through `InfluxDBClient.formatError()`:
|
||||
- Axios errors → extracted response message or request error
|
||||
- InfluxDB API errors → formatted with status code and message
|
||||
- All errors wrapped in `McpError` with appropriate error codes
|
||||
|
||||
### Query Response Parsing
|
||||
|
||||
InfluxDB returns JSON when Accept header is `application/json`. The `parseQueryResponse()` method in influx-client.ts handles multiple response formats:
|
||||
- Array of records
|
||||
- Single object
|
||||
- Nested structure with `records` array
|
||||
|
||||
Returns structured `QueryResult` with tables containing columns and records.
|
||||
|
||||
### Schema Discovery Implementation
|
||||
|
||||
`getBucketSchema()` performs multiple queries:
|
||||
1. Lists all measurements using `schema.measurements()`
|
||||
2. For each measurement, queries tags and fields in parallel
|
||||
3. Combines results into structured `BucketSchema`
|
||||
|
||||
Time ranges default to -7d for schema, -30d for measurements.
|
||||
|
||||
## Line Protocol Format
|
||||
|
||||
When writing data, use InfluxDB line protocol:
|
||||
```
|
||||
measurement[,tag=value...] field=value[,field=value...] [timestamp]
|
||||
```
|
||||
|
||||
Examples:
|
||||
```
|
||||
temperature,location=office value=22.5
|
||||
cpu,host=server1 usage=45.2 1672531200000000000
|
||||
weather,location=garden temperature=22.5,humidity=65.2
|
||||
```
|
||||
|
||||
## TypeScript Configuration
|
||||
|
||||
- Target: ES2022
|
||||
- Module: Node16 (ES modules with .js extensions in imports)
|
||||
- Strict mode enabled
|
||||
- Source maps and declarations generated
|
||||
- Output: `dist/` directory
|
||||
|
||||
All imports must use `.js` extension (e.g., `import { X } from './types.js'`) even though source files are `.ts`.
|
||||
|
||||
## Common Development Tasks
|
||||
|
||||
### Adding a New MCP Tool
|
||||
|
||||
1. Add tool definition to `ListToolsRequestSchema` handler in index.ts
|
||||
2. Add case to switch statement in `CallToolRequestSchema` handler
|
||||
3. Implement method in InfluxDBClient if calling new InfluxDB API
|
||||
4. Add types to types.ts if needed
|
||||
|
||||
### Adding a New MCP Resource
|
||||
|
||||
1. Add resource definition to `ListResourcesRequestSchema` handler
|
||||
2. Add URI handling in `ReadResourceRequestSchema` handler
|
||||
3. Implement method in InfluxDBClient to fetch data
|
||||
4. Return formatted JSON response
|
||||
|
||||
### Testing Changes
|
||||
|
||||
After modifying code:
|
||||
1. Run `npm run build` to compile
|
||||
2. Test with: `INFLUX_URL=... INFLUX_TOKEN=... INFLUX_ORG=... node dist/index.js`
|
||||
3. Server will log connection success to stderr
|
||||
4. Test in Claude Desktop or other MCP client
|
||||
|
||||
## Flux Query Language Notes
|
||||
|
||||
Flux is InfluxDB's query language. Common patterns:
|
||||
|
||||
```flux
|
||||
// Basic range query
|
||||
from(bucket: "my-bucket")
|
||||
|> range(start: -1h)
|
||||
|> filter(fn: (r) => r._measurement == "cpu")
|
||||
|
||||
// Aggregation
|
||||
from(bucket: "my-bucket")
|
||||
|> range(start: -24h)
|
||||
|> aggregateWindow(every: 1h, fn: mean)
|
||||
|
||||
// Schema discovery
|
||||
import "influxdata/influxdb/schema"
|
||||
schema.measurements(bucket: "my-bucket", start: -30d)
|
||||
```
|
||||
|
||||
Time formats: Relative (`-1h`, `-7d`, `-30d`) or absolute (`2024-01-01T00:00:00Z`)
|
||||
|
||||
## Important Constraints
|
||||
|
||||
- **Bucket Creation**: Requires organization ID (not name). Use `getOrgByName()` or read `influx://orgs` resource first.
|
||||
- **Query Organization**: If `INFLUX_ORG` not set in environment, must provide `org` parameter to `query_flux` tool.
|
||||
- **Write Precision**: Defaults to nanoseconds ('ns'). Timestamps must match specified precision.
|
||||
- **Server Communication**: MCP protocol on stdout/stdin, all logs to stderr.
|
||||
- **No Pagination**: Large result sets not automatically paginated. Users should specify appropriate time ranges.
|
||||
|
||||
## Code Style
|
||||
|
||||
- Use async/await for all I/O operations
|
||||
- Validate inputs before processing
|
||||
- Return structured JSON for tool responses
|
||||
- Include descriptive error messages
|
||||
- TypeScript strict mode compliance
|
||||
- ES modules with explicit .js imports

### 1. Create Environment File
|
||||
|
||||
Create a `.env` file in the project root:
|
||||
|
||||
```bash
|
||||
# Copy the example
|
||||
cp .env.example .env
|
||||
|
||||
# Edit with your details
|

nano .env
|
||||
```
|
||||
|
||||
Add your InfluxDB details:
|
||||
|
||||
```env
|
||||
INFLUX_URL=http://localhost:8086
|
||||
INFLUX_TOKEN=your_influxdb_token_here
|
||||
INFLUX_ORG=your_organization_name
|
||||
```
|
||||
|
||||
### 2. Build and Run
|
||||
|
||||
```bash
|
||||
# Build and start the container
|
||||
docker-compose up -d
|
||||
|
||||
# Check logs
|
||||
docker-compose logs -f
|
||||
|
||||
# Stop the container
|
||||
docker-compose down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Docker Compose Setup
|
||||
|
||||
The provided `docker-compose.yml` includes:
|
||||
|
||||
- **Multi-stage build** for optimized image size
|
||||
- **Host networking** for easy InfluxDB access
|
||||
- **Security hardening** (read-only filesystem, non-root user)
|
||||
- **Resource limits** (256MB RAM, 0.5 CPU)
|
||||
- **Health checks** for container monitoring
|
||||
- **Automatic restarts** unless manually stopped
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```bash
|
||||
# Start in background
|
||||
docker-compose up -d
|
||||
|
||||
# View logs
|
||||
docker-compose logs -f influxdb-mcp-server
|
||||
|
||||
# Restart
|
||||
docker-compose restart
|
||||
|
||||
# Stop
|
||||
docker-compose down
|
||||
|
||||
# Rebuild after code changes
|
||||
docker-compose up -d --build
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
Configure via `.env` file or docker-compose environment section:
|
||||
|
||||
| Variable | Required | Default | Description |
|
||||
|----------|----------|---------|-------------|
|
||||
| `INFLUX_URL` | Yes | `http://localhost:8086` | InfluxDB server URL |
|
||||
| `INFLUX_TOKEN` | Yes | - | Authentication token |
|
||||
| `INFLUX_ORG` | Yes | - | Organization name |
|
||||
| `NODE_ENV` | No | `production` | Node environment |
|
||||
|
||||
### Getting an InfluxDB Token
|
||||
|
||||
1. Log into InfluxDB UI (usually at http://localhost:8086)
|
||||
2. Navigate to **Data** → **Tokens** or **Load Data** → **API Tokens**
|
||||
3. Click **Generate API Token**
|
||||
4. Choose **All Access Token** or create custom permissions:
|
||||
- Read/Write access to buckets you need
|
||||
- Read access to organizations
|
||||
5. Copy the token immediately (shown only once)
|
||||
|
||||
### Token Permissions
|
||||
|
||||
For full functionality, the token should have:
|
||||
- **Read**: buckets, orgs, tasks, dashboards
|
||||
- **Write**: buckets (if you plan to write data)
|
||||
- **Delete**: buckets (if you plan to delete buckets)
|
||||
|
||||

|
||||
|
||||
## Using with Docker Desktop MCP Support
|
||||
|
||||
Docker Desktop 4.34+ includes native MCP support in the AI tools section.
|
||||
|
||||
### Setup
|
||||
|
||||
1. **Build the image:**
|
||||
```bash
|
||||
docker-compose build
|
||||
```
|
||||
|
||||
2. **Tag for Docker Desktop:**
|
||||
```bash
|
||||
docker tag influxdb-mcp-server:latest influxdb-mcp-server:latest
|
||||
```
|
||||
|
||||
3. **Configure in Docker Desktop:**
|
||||
|
||||
Open Docker Desktop settings and add to MCP servers:
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"influxdb": {
|
||||
"command": "docker",
|
||||
"args": [
|
||||
"run",
|
||||
"--rm",
|
||||
"-i",
|
||||
"--network=host",
|
||||
"-e", "INFLUX_URL=http://localhost:8086",
|
||||
"-e", "INFLUX_TOKEN=your_token_here",
|
||||
"-e", "INFLUX_ORG=your_org",
|
||||
"influxdb-mcp-server:latest"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
4. **Restart Docker Desktop** to load the MCP server
|
||||
|
||||
### Verification
|
||||
|
||||
The MCP server should appear in Docker Desktop's AI tools section. You can then use it with any integrated AI assistant.
|
||||
|
||||

|
||||
|
||||
## Using with Claude Desktop
|
||||
|
||||
### Method 1: Using Docker Directly
|
||||
|
||||
Add to `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows):
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"influxdb": {
|
||||
"command": "docker",
|
||||
"args": [
|
||||
"run",
|
||||
"--rm",
|
||||
"-i",
|
||||
"--network=host",
|
||||
"-e", "INFLUX_URL=http://localhost:8086",
|
||||
"-e", "INFLUX_TOKEN=your_influxdb_token",
|
||||
"-e", "INFLUX_ORG=your_organization",
|
||||
"influxdb-mcp-server:latest"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Method 2: Using Docker Compose
|
||||
|
||||
Create a wrapper script `run-mcp.sh`:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
docker-compose run --rm influxdb-mcp-server
|
||||
```
|
||||
|
||||
Make it executable:
|
||||
```bash
|
||||
chmod +x run-mcp.sh
|
||||
```
|
||||
|
||||
Configure Claude Desktop:
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"influxdb": {
|
||||
"command": "/Users/felix/Nextcloud/AI/projects/influxdb-mcp-server/run-mcp.sh"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Restart Claude Desktop
|
||||
|
||||
After configuration changes, fully quit and restart Claude Desktop.
|
||||
|
||||
---
|
||||
|
||||
## Networking Considerations
|
||||
|
||||
### Host Network Mode (Default)
|
||||
|
||||
The default configuration uses `network_mode: host`, which:
|
||||
|
||||
- ✅ Simplest setup
|
||||
- ✅ Direct access to InfluxDB on local network
|
||||
- ✅ No port mapping needed
|
||||
- ⚠️ Linux-only feature (works differently on macOS/Windows)
|
||||
|
||||
### Bridge Network Mode
|
||||
|
||||
If your InfluxDB is also in Docker, use bridge networking:
|
||||
|
||||
1. **Update docker-compose.yml:**
|
||||
|
||||
```yaml
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||

|
||||
```
|
||||
|
||||
2. **Connect to InfluxDB network:**
|
||||
|
||||
```bash
|
||||
# Find InfluxDB network
|
||||
docker network ls
|
||||
|
||||
# Update docker-compose.yml with correct network name
|
||||
# Then start
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
### macOS/Windows Considerations
|
||||
|
||||
On macOS and Windows, Docker runs in a VM:
|
||||
|
||||
- `host` networking works differently
|
||||
- Use explicit URLs like `http://host.docker.internal:8086`
|
||||
- Or use bridge networking with proper network setup
|
||||
|
||||
### Running with InfluxDB in Docker
|
||||
|
||||
If you're running InfluxDB itself in Docker, here's a complete setup:
|
||||
|
||||
```yaml
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
influxdb:
|
||||
image: influxdb:2.7-alpine
|
||||
container_name: influxdb
|
||||
ports:
|
||||
- "8086:8086"
|
||||
volumes:
|
||||
- influxdb-data:/var/lib/influxdb2
|
||||
- influxdb-config:/etc/influxdb2
|
||||
environment:
|
||||
- DOCKER_INFLUXDB_INIT_MODE=setup
|
||||
- DOCKER_INFLUXDB_INIT_USERNAME=admin
|
||||
- DOCKER_INFLUXDB_INIT_PASSWORD=adminpassword
|
||||
- DOCKER_INFLUXDB_INIT_ORG=myorg
|
||||
- DOCKER_INFLUXDB_INIT_BUCKET=mybucket
|
||||
- DOCKER_INFLUXDB_INIT_ADMIN_TOKEN=mytoken
|
||||
networks:
|
||||
- influx-network
|
||||
|
||||
influxdb-mcp-server:
|
||||
build: .
|
||||
container_name: influxdb-mcp-server
|
||||
environment:
|
||||
- INFLUX_URL=http://influxdb:8086
|
||||
- INFLUX_TOKEN=mytoken
|
||||
- INFLUX_ORG=myorg
|
||||
depends_on:
|
||||
- influxdb
|
||||
networks:
|
||||
- influx-network
|
||||
|
||||
networks:
|
||||
influx-network:
|
||||
driver: bridge
|
||||
|
||||
volumes:
|
||||
influxdb-data:
|
||||
influxdb-config:
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Building the Image
|
||||
|
||||
### Build Locally
|
||||
|
||||
```bash
|
||||
# Using docker-compose
|
||||
docker-compose build
|
||||
|
||||
# Using docker directly
|
||||
docker build -t influxdb-mcp-server:latest .
|
||||
|
||||
# Build with no cache
|
||||
docker-compose build --no-cache
|
||||
```
|
||||
|
||||
### Build Arguments
|
||||
|
||||
The Dockerfile supports Node.js version customization:
|
||||
|
||||
```bash
|
||||
docker build \
|
||||
--build-arg NODE_VERSION=20 \
|
||||
-t influxdb-mcp-server:latest \
|
||||
.
|
||||
```
|
||||
|
||||
### Multi-Architecture Builds
|
||||
|
||||
For running on different platforms (e.g., Raspberry Pi):
|
||||
|
||||
```bash
|
||||
# Enable buildx
|
||||
docker buildx create --use
|
||||
|
||||
# Build for multiple architectures
|
||||
docker buildx build \
|
||||
--platform linux/amd64,linux/arm64,linux/arm/v7 \
|
||||
-t influxdb-mcp-server:latest \
|
||||
--push \
|
||||
.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Container Won't Start
|
||||
|
||||
**Check logs:**
|
||||
```bash
|
||||
docker-compose logs influxdb-mcp-server
|
||||
```
|
||||
|
||||
**Common issues:**
|
||||
|
||||
1. **Missing environment variables**
|
||||
- Ensure `.env` file exists
|
||||
- Check variable names match exactly (`INFLUX_URL`, `INFLUX_TOKEN`, `INFLUX_ORG`)
|
||||
|
||||
2. **Cannot reach InfluxDB**
|
||||
- Verify `INFLUX_URL` is correct
|
||||
- Check network connectivity: `docker exec influxdb-mcp-server ping influxdb`
|
||||
- Try IP address instead of hostname
|
||||
- Check InfluxDB is running: `curl http://localhost:8086/health`
|
||||
|
||||
3. **Permission denied**
|
||||
- Container runs as non-root user
|
||||
- Check file permissions if mounting volumes
|
||||
|
||||
### Container Restarting Every 30 Seconds
|
||||
|
||||
**Symptom:** You see repeated connection messages in the logs:
|
||||
```
|
||||
InfluxDB MCP Server running on stdio
|
||||
Successfully connected to InfluxDB
|
||||
Server: influxdb (v2.7.10)
|
||||
Status: pass
|
||||
InfluxDB MCP Server running on stdio
|
||||
Successfully connected to InfluxDB
|
||||
...
|
||||
```
|
||||
|
||||
**Cause:** MCP servers communicate via stdio (stdin/stdout). Docker healthchecks interfere with stdio, causing the healthcheck to fail and Docker to restart the container.
|
||||
|
||||
**Solution:** The healthcheck is now disabled by default in docker-compose.yml:
|
||||
|
||||
```yaml
|
||||
# In docker-compose.yml
|
||||
healthcheck:
|
||||
disable: true
|
||||
|
||||
# And restart policy is set to "no" since MCP servers run on-demand
|
||||
restart: "no"
|
||||
```
|
||||
|
||||
If you have an older version, update your docker-compose.yml with these settings and rebuild:
|
||||
|
||||
```bash
|
||||
docker-compose down
|
||||
docker-compose up -d --build
|
||||
```
|
||||
|
||||
### Connection Errors
|
||||
|
||||
**Test InfluxDB connection:**
|
||||
|
||||
```bash
|
||||
# Enter container
|
||||
docker exec -it influxdb-mcp-server sh
|
||||
|
||||
# Test connection using wget (Alpine doesn't have curl by default)
|
||||
wget -O- http://localhost:8086/health
|
||||
```
|
||||
|
||||
**Check environment variables:**
|
||||
|
||||
```bash
|
||||
docker exec influxdb-mcp-server env | grep INFLUX_
|
||||
```
|
||||
|
||||
**Test token authentication:**
|
||||
|
||||
```bash
|
||||
docker exec influxdb-mcp-server sh -c '
|
||||
wget --header="Authorization: Token $INFLUX_TOKEN" \
|
||||
-O- "$INFLUX_URL/api/v2/buckets?org=$INFLUX_ORG"
|
||||
'
|
||||
```
|
||||
|
||||
### MCP Communication Issues
|
||||
|
||||
**Verify stdio communication:**
|
||||
|
||||
The MCP server communicates via stdio (stdin/stdout), not network ports.
|
||||
|
||||
```bash
|
||||
# Test directly
|
||||
echo '{"jsonrpc":"2.0","method":"initialize","params":{},"id":1}' | \
|
||||
docker run -i --rm \
|
||||
-e INFLUX_URL=http://localhost:8086 \
|
||||
-e INFLUX_TOKEN=your_token \
|
||||
-e INFLUX_ORG=your_org \
|
||||
influxdb-mcp-server:latest
|
||||
```
|
||||
|
||||
### Performance Issues
|
||||
|
||||
**Check resource usage:**
|
||||
|
||||
```bash
|
||||
docker stats influxdb-mcp-server
|
||||
```
|
||||
|
||||
**Adjust resource limits** in docker-compose.yml:
|
||||
|
||||
```yaml
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
cpus: '1.0' # Increase CPU limit
|
||||
memory: 512M # Increase memory limit
|
||||
```
|
||||
|
||||
### InfluxDB Connection Timeout
|
||||
|
||||
If queries are slow or timing out:
|
||||
|
||||
1. **Increase query timeout** in the client code
|
||||
2. **Optimize Flux queries** - use filters and limits
|
||||
3. **Check InfluxDB performance** - ensure it's not overloaded
|
||||
4. **Increase container memory** if processing large results
|
||||
|
||||
---
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Running Multiple Instances
|
||||
|
||||
Run multiple MCP servers for different InfluxDB instances:
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
influxdb-mcp-prod:
|
||||
build: .
|
||||
container_name: influxdb-mcp-prod
|
||||
environment:
|
||||
- INFLUX_URL=http://influxdb-prod:8086
|
||||
- INFLUX_TOKEN=${INFLUX_TOKEN_PROD}
|
||||
- INFLUX_ORG=production
|
||||
network_mode: host
|
||||
|
||||
influxdb-mcp-dev:
|
||||
build: .
|
||||
container_name: influxdb-mcp-dev
|
||||
environment:
|
||||
- INFLUX_URL=http://influxdb-dev:8086
|
||||
- INFLUX_TOKEN=${INFLUX_TOKEN_DEV}
|
||||
- INFLUX_ORG=development
|
||||
network_mode: host
|
||||
```
|
||||
|
||||
### Custom Logging
|
||||
|
||||
**Change log format:**
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
logging:
|
||||
driver: "json-file"
|
||||
options:
|
||||
max-size: "50m"
|
||||
max-file: "5"
|
||||
labels: "influxdb-mcp-server"
|
||||
```
|
||||
|
||||
**Use external logging:**
|
||||
|
||||
```yaml
|
||||
logging:
|
||||
driver: "syslog"
|
||||
options:
|
||||
syslog-address: "tcp://192.168.1.100:514"
|
||||
```
|
||||
|
||||
### Monitoring with Prometheus
|
||||
|
||||
Add labels for monitoring:
|
||||
|
||||
```yaml
|
||||
labels:
|
||||
- "prometheus.scrape=true"
|
||||
- "prometheus.port=9090"
|
||||
```
|
||||
|
||||
### Read-Only Filesystem
|
||||
|
||||
The container uses a read-only root filesystem for security:
|
||||
|
||||
```yaml
|
||||
read_only: true
|
||||
tmpfs:
|
||||
- /tmp # Allows temp file writes
|
||||
```
|
||||
|
||||
To allow writes to specific locations:
|
||||
|
||||
```yaml
|
||||
volumes:
|
||||
- ./data:/app/data:rw
|
||||
read_only: true
|
||||
```
|
||||
|
||||
### Custom Node.js Options
|
||||
|
||||
Pass Node.js flags:
|
||||
|
||||
```yaml
|
||||
command: ["node", "--max-old-space-size=128", "dist/index.js"]
|
||||
```
|
||||
|
||||
### Query Result Size Limits
|
||||
|
||||
For large query results, adjust Node.js memory:
|
||||
|
||||
```yaml
|
||||
environment:
|
||||
- NODE_OPTIONS=--max-old-space-size=512
|
||||
```
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
Once configured in Docker Desktop, use natural language:
|
||||
|
||||
```
|
||||
You: "List all my InfluxDB buckets"
|
||||
AI: Uses influxdb MCP resource to get buckets
|
||||
→ Returns list of buckets
|
||||
|
||||
You: "Query CPU usage for the last hour"
|
||||
AI: Uses influxdb query_flux tool
|
||||
→ Returns CPU metrics
|
||||
|
||||
You: "Write temperature sensor data"
|
||||
AI: Uses influxdb write_data tool
|
||||
→ Data written successfully
|
||||
```

|
||||
|
||||
## Basic Queries
|
||||
|
||||
### Check Server Health
|
||||
**Prompt to Claude:**
|
||||
```
|
||||
Can you check if my InfluxDB server is healthy?
|
||||
```
|
||||
|
||||
**What Claude does:**
|
||||
- Reads the `influx://health` resource
|
||||
- Returns server status, version, and health check results
|
||||
|
||||
### List All Buckets
|
||||
**Prompt to Claude:**
|
||||
```
|
||||
Show me all the buckets in my InfluxDB instance
|
||||
```
|
||||
|
||||
**What Claude does:**
|
||||
- Reads the `influx://buckets` resource
|
||||
- Returns a list of all buckets with their retention policies and metadata
|
||||
|
||||
### Query Recent Data
|
||||
**Prompt to Claude:**
|
||||
```
|
||||
Get the last hour of CPU usage data from the "system-metrics" bucket
|
||||
```
|
||||
|
||||
**What Claude does:**
|
||||
- Uses the `query_flux` tool with a query like:
|
||||
```flux

## Tips for Working with Claude
|
||||
|
||||
### Be Specific About Time Ranges
|
||||
Instead of: "Show me some data"
|
||||
Say: "Show me data from the last hour" or "Show me data from 2024-01-01 to 2024-01-31"
|
||||
|
||||
### Specify Measurements and Fields
|
||||
Instead of: "Get metrics"
|
||||
Say: "Get the CPU usage metric from the system-metrics bucket"
|
||||
|
||||
### Use Natural Language
|
||||
Claude understands context:
|
||||
- "What's in that bucket?" (if you just discussed a bucket)
|
||||
- "Show me the same thing but for yesterday"
|
||||
- "Now filter that to just server1"
|
||||
|
||||
### Ask for Explanations
|
||||
- "Explain what this Flux query does"
|
||||
- "Why did that query return empty results?"
|
||||
- "What's the best way to query this type of data?"
|
||||
|
||||
### Iterate on Queries
|
||||
Start simple and refine:
|
||||
1. "Show me CPU data"
|
||||
2. "Now average it by hour"
|
||||
3. "Now compare it to yesterday"
|
||||
4. "Now show only when it exceeded 80%"
|
||||
|
||||
### Request Data Visualization Suggestions
|
||||
- "How should I visualize this data?"
|
||||
- "What kind of chart would work best for this?"
|
||||
- "Can you format this data for plotting?"
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Time Ranges
|
||||
- Last hour: `-1h`
|
||||
- Last 24 hours: `-24h` or `-1d`
|
||||
- Last week: `-7d` or `-1w`
|
||||
- Last month: `-30d` or `-1mo`
|
||||
- Specific date: `2024-01-01T00:00:00Z`
|
||||
|
||||
### Filters
|
||||
- Single measurement: `r._measurement == "cpu"`
|
||||
- Multiple measurements: `(r._measurement == "cpu" or r._measurement == "memory")`
|
||||
- Tag filter: `r.host == "server1"`
|
||||
- Field filter: `r._field == "usage"`
|
||||
|
||||
### Aggregations
|
||||
- Mean: `aggregateWindow(every: 1h, fn: mean)`
|
||||
- Sum: `aggregateWindow(every: 1h, fn: sum)`
|
||||
- Max: `aggregateWindow(every: 1h, fn: max)`
|
||||
- Min: `aggregateWindow(every: 1h, fn: min)`
|
||||
- Count: `aggregateWindow(every: 1h, fn: count)`
|
||||
|
||||
### Grouping
|
||||
- By tag: `group(columns: ["host"])`
|
||||
- By measurement: `group(columns: ["_measurement"])`
|
||||
- By multiple columns: `group(columns: ["host", "region"])`
|
||||
|
||||
## Troubleshooting Examples
|
||||
|
||||
### Empty Results
|
||||
**Problem:** "My query returned no data"
|
||||
|
||||
**Prompt to Claude:**
|
||||
```
|
||||
I'm querying the "metrics" bucket for CPU data but getting no results. Can you help me debug?
|
||||
```
|
||||
|
||||
**Claude will:**
|
||||
1. Check if the bucket exists
|
||||
2. List measurements in the bucket
|
||||
3. Verify the time range has data
|
||||
4. Suggest alternative query approaches
|
||||
|
||||
### Wrong Data Format
|
||||
**Problem:** "My write failed with a format error"
|
||||
|
||||
**Prompt to Claude:**
|
||||
```
|
||||
I'm trying to write "cpu usage=45.2" but getting an error. What's wrong?
|
||||
```
|
||||
|
||||
**Claude will:**
|
||||
1. Explain line protocol format
|
||||
2. Show the correct format: `cpu usage=45.2` (space instead of equals after measurement)
|
||||
3. Provide more examples
|
||||
|
||||
### Performance Issues
|
||||
**Problem:** "My query is too slow"
|
||||
|
||||
**Prompt to Claude:**
|
||||
```
|
||||
This query is taking too long. Can you optimize it?
|
||||
[paste your query]
|
||||
```
|
||||
|
||||
**Claude will:**
|
||||
1. Analyze the query structure
|
||||
2. Suggest adding filters earlier in the pipeline
|
||||
3. Recommend using narrower time ranges
|
||||
4. Suggest appropriate aggregation windows
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use descriptive tag names**: `location=office` not `loc=1`
|
||||
2. **Keep line protocol consistent**: Always use the same tags for a measurement
|
||||
3. **Use appropriate timestamps**: Match your data's actual precision
|
||||
4. **Filter early in Flux queries**: Put filters right after `range()`
|
||||
5. **Use appropriate time ranges**: Don't query years of data when you need hours
|
||||
6. **Test with small queries first**: Verify logic before scaling up
|
||||
7. **Use tags for dimensions**: Put categorical data in tags, not fields
|
||||
8. **Use fields for measurements**: Put numeric data in fields
|
||||
9. **Don't create too many unique series**: Each unique tag combination creates a series
|
||||

## Technical Architecture
|
||||
|
||||
### Design Patterns
|
||||
- **Client-Server Separation**: Dedicated `InfluxDBClient` class for API communication
|
||||
- **Type Safety**: Comprehensive TypeScript types for all InfluxDB entities
|
||||
- **Error Handling**: Centralized error formatting with `McpError`
|
||||
- **Validation**: Zod schemas for environment variable validation
|
||||
- **Connection Verification**: Startup health check before serving requests
|
||||
|
||||
### Technology Stack
|
||||
```json
|
||||
{
|
||||
"runtime": "Node.js 18+",
|
||||
"language": "TypeScript 5.7+",
|
||||
"protocol": "Model Context Protocol (MCP) 1.0",
|
||||
"http-client": "axios 1.7+",
|
||||
"validation": "zod 3.24+",
|
||||
"build": "tsc (ES2022 target, Node16 modules)"
|
||||
}
|
||||
```
|
||||
|
||||
### Key Dependencies
|
||||
- `@modelcontextprotocol/sdk@^1.0.4` - MCP protocol implementation
|
||||
- `axios@^1.7.9` - HTTP client for InfluxDB REST API
|
||||
- `zod@^3.24.1` - Schema validation for configuration
|
||||
|
||||
## Implementation Highlights
|
||||
|
||||
### 1. Environment Configuration (src/index.ts)
|
||||
```typescript
|
||||
const CONFIG_SCHEMA = z.object({
|
||||
INFLUX_URL: z.string().url(),
|
||||
INFLUX_TOKEN: z.string().min(1),
|
||||
INFLUX_ORG: z.string().optional(),
|
||||
});
|
||||
```
|
||||
|
||||
### 2. InfluxDB Client (src/influx-client.ts)
|
||||
- Axios-based REST API client
|
||||
- Token authentication
|
||||
- Comprehensive error handling
|
||||
- Support for all major InfluxDB v2 endpoints
|
||||
- CSV response parsing for query results
|
||||
|
||||
### 3. MCP Server (src/index.ts)
|
||||
- Resource handlers for read-only data
|
||||
- Tool handlers for write operations
|
||||
- Proper error propagation with `McpError`
|
||||
- Graceful shutdown handling
|
||||
|
||||
### 4. Type System (src/types.ts)
|
||||
Complete TypeScript interfaces for:
|
||||
- Configuration
|
||||
- HealthStatus
|
||||
- Organizations
|
||||
- Buckets with RetentionRules
|
||||
- Tasks and Dashboards
|
||||
- QueryResults
|
||||
- Schema information
|
||||
|
||||
## Usage Workflow
|
||||
|
||||
```
|
||||
User Request → Claude Desktop → MCP Protocol → InfluxDB MCP Server → InfluxDB REST API
|
||||
↓
|
||||
User Response ← Claude Desktop ← MCP Protocol ← Response Parsing ← InfluxDB Response
|
||||
```
|
||||
|
||||
## Example Interactions
|
||||
|
||||
### Simple Query
|
||||
**User:** "Show CPU usage from the last hour"
|
||||
**Claude:** Executes `query_flux` with appropriate Flux query
|
||||
**Result:** Formatted time-series data
|
||||
|
||||
### Data Writing
|
||||
**User:** "Write temperature sensor data"
|
||||
**Claude:** Uses `write_data` with line protocol format
|
||||
**Result:** Data written to specified bucket
|
||||
|
||||
### Schema Discovery
|
||||
**User:** "What data is in this bucket?"
|
||||
**Claude:** Uses `get_bucket_schema` tool
|
||||
**Result:** List of measurements, tags, and fields
|
||||
|
||||
## Security Features
|
||||
|
||||
1. **Token-Based Auth**: Uses InfluxDB bearer tokens
|
||||
2. **Environment Isolation**: Configuration via environment variables
|
||||
3. **Input Validation**: Zod schemas validate all inputs
|
||||
4. **Error Sanitization**: No sensitive data in error messages
|
||||
5. **Least Privilege**: Supports read-only tokens
|
||||
|
||||
## Development
|
||||
|
||||
### Build Commands
|
||||
```bash
|
||||
npm install # Install dependencies
|
||||
npm run build # Compile TypeScript
|
||||
npm run watch # Watch mode for development
|
||||
npm start # Run the server
|
||||
```
|
||||
|
||||
### Testing the Server
|
||||
```bash
|
||||
INFLUX_URL=http://localhost:8086 \
|
||||
INFLUX_TOKEN=your_token \
|
||||
INFLUX_ORG=your_org \
|
||||
node dist/index.js
|
||||
```
|
||||
|
||||
## Deployment
|
||||
|
||||
### Claude Desktop Integration
|
||||
Add to `claude_desktop_config.json`:
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"influxdb": {
|
||||
"command": "node",
|
||||
"args": ["/absolute/path/to/dist/index.js"],
|
||||
"env": {
|
||||
"INFLUX_URL": "http://localhost:8086",
|
||||
"INFLUX_TOKEN": "your_token",
|
||||
"INFLUX_ORG": "your_org"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Standalone Usage
|
||||
The server can also run as a standalone stdio-based MCP server for integration with other MCP clients.
|
||||
|
||||
## Code Quality
|
||||
|
||||
- ✅ Strict TypeScript compilation
|
||||
- ✅ Comprehensive type definitions
|
||||
- ✅ Error handling at every layer
|
||||
- ✅ Input validation
|
||||
- ✅ Detailed inline documentation
|
||||
- ✅ Consistent code style
|
||||
- ✅ No external runtime dependencies beyond Node.js
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
1. **Async Operations**: All I/O is asynchronous
|
||||
2. **Streaming Support**: Ready for large query results
|
||||
3. **Connection Pooling**: Axios handles connection reuse
|
||||
4. **Timeout Configuration**: 30-second default timeout
|
||||
5. **Error Recovery**: Graceful error handling prevents crashes
|
||||
|
||||
## Extensibility
|
||||
|
||||
The architecture supports easy addition of:
|
||||
- New MCP resources (add to resource list)
|
||||
- New MCP tools (add to tools list + handler)
|
||||
- New InfluxDB API endpoints (add methods to client)
|
||||
- Custom Flux query builders
|
||||
- Additional validation logic
|
||||
|
||||
## Documentation Coverage
|
||||
|
||||
1. **README.md**: Complete setup and usage guide
|
||||
2. **QUICKSTART.md**: 5-minute getting started guide
|
||||
3. **EXAMPLES.md**: 650+ lines of real-world examples
|
||||
4. **CHANGELOG.md**: Version history
|
||||
5. **Inline Comments**: Throughout source code
|
||||
6. **Type Definitions**: Self-documenting TypeScript types
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
Recommended testing approach:
|
||||
1. Manual testing with real InfluxDB instance
|
||||
2. Integration testing with Claude Desktop
|
||||
3. Unit testing for InfluxDBClient methods
|
||||
4. Schema validation testing
|
||||
5. Error handling verification
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **Query Response Format**: Simplified parsing of InfluxDB JSON responses
|
||||
2. **Field Type Detection**: InfluxDB doesn't always provide type information
|
||||
3. **Large Result Sets**: No automatic pagination (relies on user-specified time ranges)
|
||||
4. **Advanced Features**: Some InfluxDB v2 features not yet exposed (e.g., annotations, variables)
|
||||
|
||||

||||
Edit `~/.config/Claude/claude_desktop_config.json` (same format as macOS).
|
||||
|
||||
### Windows
|
||||
|
||||
Edit `%APPDATA%\Claude\claude_desktop_config.json` (same format as macOS).
|
||||
|
||||
**Important:** Replace `/Users/felix/Nextcloud/AI/projects/influxdb-mcp-server` with the actual absolute path to your installation.
|
||||
|
||||
## Step 5: Restart Claude Desktop
|
||||
|
||||
1. Completely quit Claude Desktop
|
||||
2. Start Claude Desktop again

## Step 6: Test with Claude
|
||||
|
||||
Try these prompts:
|
||||
|
||||
### Test 1: Check Connection
|
||||
```
|
||||
Is my InfluxDB server healthy?
|
||||
```
|
||||
|
||||
Expected: Claude will read the health resource and tell you the server status.
|
||||
|
||||
### Test 2: List Buckets
|
||||
```
|
||||
What buckets are in my InfluxDB instance?
|
||||
```
|
||||
|
||||
Expected: Claude will list all your buckets.
|
||||
|
||||
### Test 3: Write Test Data
|
||||
```
|
||||
Write a test temperature reading of 22.5 to a bucket called "test-bucket"
|
||||
(use my default organization)
|
||||
```
|
||||
|
||||
Expected: Claude will write data using line protocol.
|
||||
|
||||
### Test 4: Query Data
|
||||
```
|
||||
Show me the last 10 minutes of data from "test-bucket"
|
||||
```
|
||||
|
||||
Expected: Claude will execute a Flux query and return results.
|
||||
|
||||
## Troubleshooting

||||
1. In Claude, ask: "What organizations are available?"
|
||||
2. Update `INFLUX_ORG` with the correct name
|
||||
3. Restart Claude Desktop
|
||||
|
||||
### Claude doesn't see the server
|
||||
|
||||
**Problem:** MCP server not loading
|
||||
|
||||
**Solutions:**
|
||||
1. Verify the path in `claude_desktop_config.json` is absolute
|
||||
2. Check that `dist/index.js` exists and is executable
|
||||
3. Look at Claude Desktop logs:
|
||||
- macOS: `~/Library/Logs/Claude/`
|
||||

|
||||
4. Ensure JSON syntax is correct (no trailing commas)
|
||||
5. Restart Claude Desktop completely
|
||||
|
||||
### "Module not found" error
|
||||
|
||||
**Problem:** Dependencies not installed
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
cd /Users/felix/Nextcloud/AI/projects/influxdb-mcp-server
|
||||
npm install
|
||||
npm run build
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
Now that you're set up:
|
||||
|
||||
1. **Read EXAMPLES.md** for real-world usage patterns
|
||||
2. **Explore your data** by asking Claude to analyze your buckets
|
||||
3. **Create dashboards** by having Claude query and format data
|
||||
4. **Set up monitoring** by writing periodic data from your applications
|
||||
|
||||
## Common First Tasks
|
||||
|
||||
### Explore Your Data
|
||||
```
|
||||
What measurements are in my "telegraf" bucket?
|
||||
```
|
||||
|
||||
### Analyze Recent Metrics
|
||||
```
|
||||
Show me the average CPU usage across all servers in the last hour
|
||||
```
|
||||
|
||||
### Create a New Bucket
|
||||
```
|
||||
Create a bucket called "application-metrics" with a 90-day retention policy
|
||||
```
|
||||
|
||||
### Write Application Metrics
|
||||
```
|
||||
Write the following metrics to "application-metrics":
|
||||
- API response time: 125ms for /users endpoint
|
||||
- API response time: 89ms for /posts endpoint
|
||||
```
|
||||
|
||||
### Generate Reports
|
||||
```
|
||||
Create a daily summary of temperature readings from all sensors
|
||||
```
|
||||
|
||||
## Pro Tips
|
||||
|
||||
1. **Start with simple queries** and build up complexity
|
||||
2. **Use natural language** - Claude understands context
|
||||
3. **Ask for explanations** if you're learning Flux
|
||||
4. **Iterate on queries** - refine as you go
|
||||
5. **Let Claude help with schema** - ask what data is available first
|
||||

## Example Interactions
|
||||
|
||||
Here are some example interactions you can have with Claude using this MCP server:
|
||||
|
||||
### Query Recent Data
|
||||
> "Show me the average CPU usage from the 'system-metrics' bucket over the last hour"
|
||||
|
||||
Claude will use the `query_flux` tool to execute an appropriate Flux query.
|
||||
|
||||
### Write Sensor Data
|
||||
> "Write temperature readings: office sensor at 22.5°C and warehouse sensor at 18.3°C to the 'sensors' bucket"
|
||||
|
||||
Claude will format the data in line protocol and use the `write_data` tool.
|
||||
|
||||
### Explore Schema
|
||||
> "What measurements and fields are available in the 'application-logs' bucket?"
|
||||
|
||||
Claude will use the `get_bucket_schema` tool to discover the data structure.
|
||||
|
||||
### Create New Bucket
|
||||
> "Create a new bucket called 'test-metrics' with a 30-day retention policy"
|
||||
|
||||
Claude will first get the organization ID from resources, then use the `create_bucket` tool.
|
||||
|
||||
### Health Check
|
||||
> "Is my InfluxDB server running properly?"
|
||||
|
||||
Claude will read the `influx://health` resource to check server status.

|
||||
- `schema.measurements()` - List measurements
|
||||
- `schema.measurementTagKeys()` - List tag keys
|
||||
- `schema.measurementFieldKeys()` - List field keys
|
||||
|
||||
## Development
|
||||
|
||||
### Build
|
||||
```bash
|
||||
npm run build
|
||||
```
|
||||
|
||||
### Watch Mode
|
||||
```bash
|
||||
npm run watch
|
||||
```
|
||||
|
||||
### Run Directly
|
||||
```bash
|
||||
npm start
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
For debugging, you can run the server with additional logging:
|
||||
```bash
|
||||
node dist/index.js
|
||||
```
|
||||
|
||||
The server logs to stderr, so it won't interfere with the MCP protocol communication on stdout.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Connection Issues
|
||||
|
||||
**Problem:** "No response from InfluxDB server"
|
||||
|
||||
**Solutions:**
|
||||
- Verify `INFLUX_URL` is correct and InfluxDB is running
|
||||
- Check network connectivity: `curl http://localhost:8086/health`
|
||||
- Ensure no firewall is blocking the connection
|
||||
|
||||
### Authentication Errors
|
||||
|
||||
**Problem:** "InfluxDB API error (401): unauthorized"
|
||||
|
||||
**Solutions:**
|
||||
- Verify your `INFLUX_TOKEN` is correct
|
||||
- Check token permissions in InfluxDB UI
|
||||
- Ensure token hasn't expired
|
||||
|
||||
### Query Failures
|
||||
|
||||
**Problem:** Flux query returns an error
|
||||
|
||||
**Solutions:**
|
||||
- Validate Flux syntax using InfluxDB UI Query Builder
|
||||
- Check bucket name and organization are correct
|
||||
- Ensure time range contains data
|
||||
- Verify measurement and field names exist
|
||||
|
||||
### Resource Not Found
|
||||
|
||||
**Problem:** "Unknown resource URI"
|
||||
|
||||
**Solutions:**
|
||||
- Check the URI format matches documented patterns
|
||||
- For bucket-specific resources, verify the bucket ID exists
|
||||
- Use `influx://buckets` to list available bucket IDs
|
||||
|
||||
### Tool Execution Errors
|
||||
|
||||
**Problem:** "Tool execution failed"
|
||||
|
||||
**Solutions:**
|
||||
- Verify all required parameters are provided
|
||||
- Check parameter types match the schema
|
||||
- For write operations, validate line protocol format
|
||||
- For bucket creation, ensure organization ID (not name) is used
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **Token Storage**: Never commit `.env` files or tokens to version control
|
||||
2. **Token Permissions**: Use least-privilege tokens with only necessary permissions
|
||||
3. **Network Security**: Use HTTPS for remote InfluxDB instances
|
||||
4. **Input Validation**: The server validates all inputs using Zod schemas
|
||||
5. **Error Messages**: Sensitive information is not exposed in error messages
|
||||
|
||||
## Line Protocol Format
|
||||
|
||||
When writing data, use the InfluxDB line protocol format:
|
||||
|
||||
```
|
||||
<measurement>[,<tag_key>=<tag_value>[,<tag_key>=<tag_value>]] <field_key>=<field_value>[,<field_key>=<field_value>] [<timestamp>]
|
||||
```
|
||||
|
||||
**Examples:**
|
||||
|
||||
```
|
||||
# Simple measurement
|
||||
temperature value=22.5
|
||||
|
||||
# With tags
|
||||
temperature,location=office,sensor=1 value=22.5
|
||||
|
||||
# Multiple fields
|
||||
weather,location=garden temperature=22.5,humidity=65.2
|
||||
|
||||
# With timestamp (nanoseconds)
|
||||
cpu,host=server1 usage=45.2 1672531200000000000
|
||||
|
||||
# Multiple lines (batch write)
|
||||
cpu,host=server1 usage=45.2 1672531200000000000
|
||||
cpu,host=server2 usage=38.7 1672531200000000000
|
||||
memory,host=server1 used=8589934592 1672531200000000000
|
||||
```
|
||||
|
||||
## Flux Query Examples
|
||||
|
||||
### Basic Query
|
||||
```flux
|
||||
from(bucket: "my-bucket")
|
||||
|> range(start: -1h)
|
||||
|> filter(fn: (r) => r._measurement == "cpu")
|
||||
```
|
||||
|
||||
### Aggregation
|
||||
```flux
|
||||
from(bucket: "my-bucket")
|
||||
|> range(start: -24h)
|
||||
|> filter(fn: (r) => r._measurement == "temperature")
|
||||
|> aggregateWindow(every: 1h, fn: mean)
|
||||
```
|
||||
|
||||
### Multiple Filters
|
||||
```flux
|
||||
from(bucket: "my-bucket")
|
||||
|> range(start: -1h)
|
||||
|> filter(fn: (r) => r._measurement == "cpu" and r.host == "server1")
|
||||
|> filter(fn: (r) => r._field == "usage")
|
||||
```
|
||||
|
||||
### Join Data
|
||||
```flux
|
||||
cpu = from(bucket: "my-bucket")
|
||||
|> range(start: -1h)
|
||||
|> filter(fn: (r) => r._measurement == "cpu")
|
||||
|
||||
memory = from(bucket: "my-bucket")
|
||||
|> range(start: -1h)
|
||||
|> filter(fn: (r) => r._measurement == "memory")
|
||||
|
||||
join(tables: {cpu: cpu, memory: memory}, on: ["_time", "host"])
|
||||
```
