[FEAT] Add OpenMetrics / Prometheus metrics endpoint

[kinghrothgar]

It would be very nice to be able to pull data from scrutiny into Prometheus. This would allow me to leverage my standardized alert system.

https://prometheus.io/docs/instrumenting/writing_exporters/

It should feasibly be a /metrics route that translates the results of a DB query into the simple OpenMetrics format. If there is interest in merging this feature, I can look into getting together a PR.

Hey, so the idea would be to allow Prometheus to query smart data from Scrutiny?
Doesn't Prometheus have a SMART data collector already?

[kinghrothgar]

There seems to a not particularly maintained exporter here (last interaction of the maintainer was over a year ago): https://github.com/Sheridan/smartctl_exporter

The only other option I have found is to do something like this with a node_exporter script, but this example script leaves much interpretation to be desired (as noted in the top comment): https://github.com/prometheus-community/node-exporter-textfile-collector-scripts/blob/master/smartmon.sh

Hey! Is there any work on this feature? Or is this abandoned?

Hey, I've been looking for the same thing! I've been using Scrutiny for a very long time and would like to bank on its reliability to push stats in Prometheus and Grafana.

I'm open to contributions to support this kind of functionality, however I dont use Prometheus so I will be unable to develop this myself unfortunately

Bringing this feature will benefit Windows users as well, as there are no exporters for that on Windows (that I know of).
Meaning that scrutiny will be the only(?) maintained exporter for SMART data in that platform

[proffalken]

Whilst I don't have the skills to develop this, I'm more than happy to test it if it gets developed.

I think this could be realized in running PCP's pmcd, pmda-smart (to read smart data) and pmproxy which can offer the data in Openmetrics format.
