Prometheus Frigate stats exporter

[bairhys]

I have made a simple Prometheus Frigate stats exporter docker container that exports most of the data at /api/stats. This allows Prometheus to record the stats and Grafana to show the data, e.g. graph inference speeds, camera detection fps, cpu/gpu usage etc. See here for how to run the container and a Grafana screenshot. I have been using it with the frigate:0.12.0-beta6 to 8 docker images with an Intel OpenVINO detector.

    cpu_usages.add_metric([d], float(data['cpu_usages'][d]['cpu']))
ValueError: could not convert string to float: 'id,'

Thats the log from container.

Thanks for testing. I have updated the container, could you try again?

Now container is starting but http://*****:9100 or ../metrics shows:

Not sure why it is not displaying the more interesting data like cameras and detectors, since I am also on same version as you (0.12.0-27a31e7).

Maybe it is best to continue this issue here
