Internal Prometheus Metrics to Watch?

[Dave Cadwallader]

As I feed more metrics to my Prometheus server, I want to watch internal metrics to make sure I'm not over-taxing it.

CPU: 2 cores

RAM: 8 GB

A couple of questions:

1) Is there a recommended Grafana dashboard for tracking Prometheus' internal health?

2) Which are the most important metrics to watch, and what would be the ballpark thresholds to monitor?

3) Any node_exporter metrics to watch out for on my Prometheus servers?

Thanks!

Dave

This one has a lot of detail if you are trying to figure out what is going on or ask for help with performance / memory issues:

https://grafana.com/dashboards/3834

There are some other prometheus one you can just search the directory on grafana, of course.

Thanks! That dashboard is helpful. I am still not sure what metrics and values of those metrics would constitute a problem though. Any general advice would be appreciated!

Yes I agree, I have only a vague idea what those metrics are about myself.
