Want to monitor system usage on my server - Grafana my best option?
The number of containers I'm running on my server keeps increasing, and I want to make sure I'm not pushing it beyond its capabilities. I would like a simple interface accessible on my home network (that does not make any fishy connections out) that shows me CPU and RAM-usage, storage status of my hard drives, and network usage. It should be FOSS, and I want to run it as a Docker container.
Is Grafana the way to go, or are there other options I should consider?
I would personally use grafana, but zabbix is also a good choice.
Thanks for your input!
Munin feels a little old and crusty, but just works. Over 20 years old now.
Cockpit is a simpler choice for that.
Thanks for the recommendation! I'll check it out. Simple sounds good for mye use case.
Possibly a bit overkill, but I’m running Zabbix in 3 containers (Core, WebUI, database). Using its agent installed on all my machines, I can monitor basically anything. Of course, you can set limits, alerts, draw graphs, etc.
That looks cool, but as you said maybe a little overkill, hehe. I'll still check it out in more detail, in any case good for later!
Glances could be a good option, it's pretty bare bones, but it covers the basics and serves my needs well enough

The last time I've used glances - to be fair, some years ago - it caused the main CPU usage on my Raspberry Pi 3. However, looks like it's been fixed recently.
Webmin is worth giving a try depending on your needs, it's pretty lightweight compared to some others:

I won't waste time on things other than grafana if your setup is serious. Because you will always want more. Log aggregation, log query, alerts, tracing, profiling, oidc, s3 bucket, more and more dashboards. It's addictive. Why waste time to redo it in the future?
I have Netdata running in a container, which has a useful all-in-one-pane view, and it does a good job of auto detecting other containers and the host OS. Its essentially zero config.
It also has alerting capability, which is not zeroconf (configuring it properly is a bit of a chore). 😅
They try to push a pro/paid version, but it's subtle and completely optional (a bit like the way Portainer does it).
Have a look at glances. It seems quite ok.
