Is Prometheus suitable for os process monitoring?

[Rafał Radecki]

Hi All.

I am learning about prometheus and creating a graphing/alerting setup with grafana/alertmanager. Prometheus seems to be a perfect fit for time series data but I wonder I "standard" process level monitoring can be done with it? For example if it is possible without a custom exporter to check status of a systemctl service or an arbitrary process on Linux? Or maybe do you know any exporters suitable for such task?

BR,

Rafal.

For systemd services, the "systemd" collector module in the Node Exporter already exports the current state: https://github.com/prometheus/node_exporter

Note that you'll have to explicitly enable that module via the --collectors.enabled flag, as it's in the list of modules which is disabled by default.

https://github.com/ncabatoff/process-exporter can be used for monitoring processes that are impractical to instrument directly.
