Hello folks,
I am brand new to Prometheus and Grafana, so please be kind.
I use ZFS and Sanoid, which only has Nagios alerts for monitoring. I saw someone requested Prometheus ones here:
and thought it should not be too hard to get these into Grafana. Sanoid has no daemon or anything, it is just a script that autosnapshots/prunes/outputs health data about your ZFS pools/snapshots etc.
I set up a free tier Grafana Cloud account and added the relevant server using the quickstart Linux grafana-easystart-app/linux-node instructions. My metrics appear in the dashboard etc, so first hurdle jumped.
Reading through quite a lot of the docs, I thought a sensible approach to this would be to convert these metrics into a .prom textfile and pull it in using the textfile collector.
I understood that grafana-agent had a subset of the functionality of the prometheus agent and it seems to be doing the node_exporter functions, but I cannot figure out how to make it pull in the metrics from the file. I tried:
/usr/bin/grafana-agent --config.file /etc/grafana-agent.yaml --log.level error --collector.textfile.directory /etc/grafana-text-file-collectors/
but --collector.textfile.directory
is not a valid flag and none of the other flags seemed like an equivalent.
I like the simplicity of the grafana-agent and hoped to just add a few metrics into the information it is already scraping off the machine – is there an obvious way to do this that I’m missing?
This:
sounded relevant, but still did not say how to actually do it.
