What sort of things do y'all monitor with Grafana / Beszel / etc.? (lemmy.world)

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?

I mean, I got the whole set of default dashboards, some for networking and one each for backups (k8up) and Postgres (CloudNativePG), but I don't look at them often, usually only if something's wrong. I also have logs available via Grafana, but I don't have any dashboards for that, I just query what I need. If I ever have enough time and motivation, some things I'd put on a kind of overview dashboard would be in addition to your list:

zpool health (scrub status, IO etc.)
list of crashing pods
list of warnings from FluxCD (e.g. application upgrade failures or invalid manifests)
list of failing persistent volumes

I think aggregating logs would be a good choice, yeah. My homelab is distributed across 5 machines, so it's been getting a little unruly to ssh into them all the time. I actually haven't taken a look at premade dashboards - completely forgot those exist. I've just been writing the PromQL by hand to learn how it all works before adding premade things

Yeah, for most things, a premade dashboard exists, and if it isn't fully to your liking, just customize it. Also for more professionally maintained metrics exporters like the node-exporter, there's usually an official dashboard. But learning PromQL before relying on premade stuff is probably a good idea, so you know how to adapt them to your needs
