Frigate NVR (beta)

Whether Frigate still sees: cameras that stopped delivering frames, detector inference speed and hangs (Coral, GPU, CPU), frame rates, the disk holding the recordings and updates.

Beta

Written from the vendor’s API documentation and tested against realistic recorded-style responses, not yet against a live instance. Tell us what you see.

Network ports to open

From the DumbMonit server (or its relay agent) to the device:

Port	Protocol	Purpose
5000	TCP	API (HTTP, default, no login)
8971	TCP	Only with the authenticated port behind a bearer-token proxy

The failure worth watching: a camera that stopped sending frames. Frigate shows it only in its interface; its recordings and detections simply stop. camera_fps at zero is the most reliable sign. A detector stuck on one inference, or a full recording disk, are the other two.

What it watches

All metrics are prefixed dumbmonit_frigate_.

Metric	What	Labels
version_info	value 1	version
update_available	1 when Frigate knows a newer release	latest_version
uptime_seconds, detection_fps	time since Frigate started; detections per second, all cameras
cameras_total, cameras_offline	cameras, and those delivering no frames
camera_online, camera_fps	1 while frames arrive; frames per second received (at most 32 cameras)	camera
camera_process_fps, camera_skipped_fps, camera_detection_fps	frames processed, dropped for lack of time, and sent to detection	camera
detector_inference_ms	inference time of each detector	detector
detector_busy_seconds	how long a detector has been on the same inference (0 when idle)	detector
storage_used_percent, storage_free_bytes	recording disks (in-memory mounts are left out)	path

The built-in rules that apply: Frigate camera offline, Frigate detector stuck, Frigate storage almost full, Frigate update available, plus Monitor unreachable.

Let DumbMonit read Frigate’s statistics

1. Nothing to install: check from the DumbMonit host that Frigate’s API answers on port 5000.

   curl http://frigate.lan:5000/api/version

2. If a proxy in front of Frigate expects a token (port 8971 requires a login), choose Bearer token below; otherwise choose No authentication.

3. In DumbMonit, enter Frigate’s address, for example “frigate.lan”.

Warning

Port 5000 has no login and gives full control of Frigate: expose it only to DumbMonit, never to the internet. A camera you turned off in Frigate’s settings also reads as offline.

Credentials

Credential	Fields
No authentication	Port 5000, the internal API.
Bearer token	Sent as Authorization: Bearer …, for a proxy that expects it.

Address: a host name (frigate.lan), host:port, or a full URL with a path prefix. Options: protocol (HTTP by default), port (5000), certificate check and request timeout (15 s).
