Description

At the moment we don't scrape metrics from the prometheus server itself.

If we did, we could
  • track and monitor prometheus growth (rate of expansion, and maybe use predict linear to forecast)
  • observe scrape sample sizes and growth over time - look for anomalies
  • alert based on issues in the tsdb/wal
  • pick up and alert on cephadm not responding to sd refresh requests
    etc etc

I don't think it covers everything you want but Prometheus has a mixin: https://github.com/prometheus/prometheus/tree/main/documentation/prometheus-mixin but I guess you could also try to add the missing piece there as well.

Thanks for writing down the RFE proposal. Please, can you put some more information about what config needs to be add in order to support this new feature. Any pointers to the docs are also more than welcome.
