Prometheus metrics #10

Closed kondas closed 1 month ago

kondas commented 2 months ago

It would be a very useful feature to be able to monitor the fan speeds with Prometheus, plus the go application stats of OpenLinkHub. I am happy to help with creating a Grafana dashboard for the metrics.

You already have data exposed via JSON on http://127.0.0.1:27003/api/devices endpoint. I don't think much people run prometheus on their home machines and scrape metrics. You would need multiple exporters in order to do so, from node_exporter to others. Grafana can process JSON format that OpenLinkHub already provides back.

Its using standard prometheus client lib, so overall app stats are also included, but I didn't paste it here due to size of it.

Will be pushed out in 0.1.7 version.

serial should be your key factor when doing prom query to fetch all the devices from hub. You can iterate over device list and extract serial via regex in Grafana.

Hi! It looks promising, thanks for adding the feature. I'm sure many others will find it useful. And yes, many exporters needed indeed, OpenLinkHub will be the 9th scrape target on my system. I'm eager to try it out, and will provide a dashboard ASAP.
