Metrics

Frigate exposes Prometheus metrics at the /api/metrics endpoint that can be used to monitor the performance and health of your Frigate instance.

Available Metrics​

System Metrics​

  • frigate_cpu_usage_percent{pid="", name="", process="", type="", cmdline=""} - Process CPU usage percentage
  • frigate_mem_usage_percent{pid="", name="", process="", type="", cmdline=""} - Process memory usage percentage
  • frigate_gpu_usage_percent{gpu_name=""} - GPU utilization percentage
  • frigate_gpu_mem_usage_percent{gpu_name=""} - GPU memory usage percentage

Camera Metrics​

  • frigate_camera_fps{camera_name=""} - Frames per second being consumed from your camera
  • frigate_detection_fps{camera_name=""} - Number of times detection is run per second
  • frigate_process_fps{camera_name=""} - Frames per second being processed
  • frigate_skipped_fps{camera_name=""} - Frames per second skipped for processing
  • frigate_detection_enabled{camera_name=""} - Detection enabled status for camera
  • frigate_audio_dBFS{camera_name=""} - Audio dBFS for camera
  • frigate_audio_rms{camera_name=""} - Audio RMS for camera

Detector Metrics​

  • frigate_detector_inference_speed_seconds{name=""} - Time spent running object detection in seconds
  • frigate_detection_start{name=""} - Detector start time (unix timestamp)

Storage Metrics​

  • frigate_storage_free_bytes{storage=""} - Storage free bytes
  • frigate_storage_total_bytes{storage=""} - Storage total bytes
  • frigate_storage_used_bytes{storage=""} - Storage used bytes
  • frigate_storage_mount_type{mount_type="", storage=""} - Storage mount type info

Service Metrics​

  • frigate_service_uptime_seconds - Uptime in seconds
  • frigate_service_last_updated_timestamp - Stats recorded time (unix timestamp)
  • frigate_device_temperature{device=""} - Device Temperature

Event Metrics​

  • frigate_camera_events{camera="", label=""} - Count of camera events since exporter started

Configuring Prometheus​

To scrape metrics from Frigate, add the following to your Prometheus configuration:

scrape_configs:
  - job_name: 'frigate'
    metrics_path: '/api/metrics'
    static_configs:
      - targets: ['frigate:5000']
    scrape_interval: 15s

Example Queries​

Here are some example PromQL queries that might be useful:

# Average CPU usage across all processes
avg(frigate_cpu_usage_percent)

# Total GPU memory usage
sum(frigate_gpu_mem_usage_percent)

# Detection FPS by camera
rate(frigate_detection_fps{camera_name="front_door"}[5m])

# Storage usage percentage
(frigate_storage_used_bytes / frigate_storage_total_bytes) * 100

# Event count by camera in last hour
increase(frigate_camera_events[1h])

Grafana Dashboard​

You can use these metrics to create Grafana dashboards to monitor your Frigate instance. Here's an example of metrics you might want to track:

  • CPU, Memory and GPU usage over time
  • Camera FPS and detection rates
  • Storage usage and trends
  • Event counts by camera
  • System temperatures

A sample Grafana dashboard JSON will be provided in a future update.

Metric Types​

The metrics exposed by Frigate use the following Prometheus metric types:

  • Counter: Cumulative values that only increase (e.g., frigate_camera_events)
  • Gauge: Values that can go up and down (e.g., frigate_cpu_usage_percent)
  • Info: Key-value pairs for metadata (e.g., frigate_storage_mount_type)
