Meraki Dashboard Exporter

A Prometheus exporter for Cisco Meraki Dashboard API metrics with OpenTelemetry support.

Features

• Collects metrics from all Meraki device types (MS, MR, MV, MT, MX, MG)
• Organization-level metrics (API usage, licenses, device counts)
• Device-specific metrics (status, performance, sensor readings)
• Async collection for improved performance
• Dual metric export: Prometheus /metrics endpoint + automatic OpenTelemetry export
• Distributed tracing: Full request tracing with OpenTelemetry instrumentation
• Structured logging with JSON output and trace correlation
• Docker support with health checks
• Configurable collection intervals

Quick Start

Using Docker (Recommended)

1. Copy .env.example to .env and add your Meraki API key:

   cp .env.example .env
   # Edit .env and set: MERAKI_EXPORTER_MERAKI__API_KEY=your_api_key_here

2. Run with Docker Compose:

   docker-compose up -d

3. Access metrics at http://localhost:9099/metrics

Building from Source

If you need to build the Docker image from source:

# Build the image
docker build -t meraki-dashboard-exporter .

# Run the container
docker run -d \
  -e MERAKI_EXPORTER_MERAKI__API_KEY=your_api_key_here \
  -p 9099:9099 \
  meraki-dashboard-exporter

OpenTelemetry Support

The exporter provides comprehensive OpenTelemetry support when enabled:

Metrics: All Prometheus metrics are automatically mirrored to OTEL

• Use existing Prometheus dashboards while sending to OTEL backends
• No code changes needed - new metrics are automatically exported

Tracing: Distributed tracing for all operations

• Every Meraki API call is traced with timing and metadata
• Automatic instrumentation of HTTP, threading, and logging
• Configurable sampling rates for production use
• Correlation with logs via trace IDs
• Automatic RED metrics from spans (Rate, Errors, Duration)

Logs: Structured logging with trace correlation

• Automatic trace context injection (trace_id, span_id)
• All logs include trace context when within a span
• Structured log fields preserved for easy parsing
• Compatible with log aggregation systems

Benefits:

• Full observability with metrics, traces, and logs
• Debug slow API calls and identify bottlenecks
• Track request flow across the entire system
• Compatible with Jaeger, Tempo, Datadog, New Relic, etc.

Enabling OpenTelemetry

Set these environment variables:

# Enable OTEL export
export MERAKI_EXPORTER_OTEL__ENABLED=true

# Set the OTEL collector endpoint
export MERAKI_EXPORTER_OTEL__ENDPOINT=http://localhost:4317

# Optional: Configure export interval (default: 60 seconds)
export MERAKI_EXPORTER_OTEL__EXPORT_INTERVAL=30

# Optional: Add resource attributes
export MERAKI_EXPORTER_OTEL__RESOURCE_ATTRIBUTES='{"environment":"production","region":"us-east"}'

# Optional: Configure trace sampling rate (default: 0.1 = 10%)
export MERAKI_EXPORTER_OTEL__SAMPLING_RATE=0.1

Docker Compose Example

services:
  meraki-exporter:
    image: meraki-dashboard-exporter
    environment:
      - MERAKI_EXPORTER_MERAKI__API_KEY=${MERAKI_EXPORTER_MERAKI__API_KEY}
      - MERAKI_EXPORTER_OTEL__ENABLED=true
      - MERAKI_EXPORTER_OTEL__ENDPOINT=http://otel-collector:4317
    ports:
      - "9099:9099"

  otel-collector:
    image: otel/opentelemetry-collector-contrib:latest
    command: ["--config=/etc/otel-collector-config.yaml"]
    volumes:
      - ./otel-collector-config.yaml:/etc/otel-collector-config.yaml
    ports:
      - "4317:4317"  # OTLP gRPC receiver

See OTEL.md for detailed OpenTelemetry configuration and TRACING.md for distributed tracing documentation.
