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?
Netdata is far simpler to set up than Grafana from what I remember but it does phone home by default (you can disable it in via options in docker or something). On one of my servers it doesn’t show container names which is kinda a bummer but I didn’t care enough to troubleshoot that, since I mostly ssh in and use btop anyway …
Seconded. Netdata has a generic and forgettable name but is powerful and easy to set up.
Open source, runs in docker or LXC. Web UI with more metrics than you will ever want, plus plugins. Support for alerts and some log aggregation, though I have not tried logging yet.
