Have been working on my Grafana dashboard recently and am thinking about what else I could add. So far, I have:
- CPU usage and temperature
- Memory usage
- Network usage
- Backrest daily backup status
- SMART status of drives
- CPU and memory usage of containers
Anything else that you find useful? I have a few other ideas, but am curious what others have up. Is everything on one scrollable dashboard, or do you have it organized across multiple?
Size is a great idea, thanks. The problem with backup age is that Backrest doesn’t expose a metric for when the backup was attempted, so right now it’s just checking for failure status daily. That, of course, fails if backrest doesn’t attempt a backup for whatever reason. Chances of that happening, I don’t know, but I’ll have to look into implementing the metric (or label, I suppose) myself.
What I do for that is turn it around, instead of checking for a failure I alert on the absence of a success. backrest has hooks, so on snapshot success it pings a push monitor in uptime kuma (healthchecks.io works the same), and if no ping arrives in ~26h it alerts. That way it catches the backup that never ran, which is the one that scares me the most I guess
