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?
it’s a bit more complicated than that. grafana is only for displaying of the collected info. you still need a database, and something that collects data from systems.
what I do is grafana + prometheus for storage + prometheusnode exporter for collection.
but, I’m not totally satisfied with this setup, because long term storage is unsolved (cranking up the retention time in prom will maje sure it’ll cost a lot of storage after a few months), and I haven’t found a way to collect info about top users of resources (e.g. top 10 processes by cpu usage)Glances could be a good option, it’s pretty bare bones, but it covers the basics and serves my needs well enough
btw grafana does make connections out, at least for when installing plugins, possibly more.
if you are not in the EU, they even load fucking fecesbook scripts on their main website! a few months ago that was happening in the EU too. if you’re in the EU, you can see it for yourself with thea VPN or the Tor browser, request a new circuit until the bottom one is USA or something like that, and check the network traffic with the devtools (reload the site if you don’t see it there)
even if this is not the case in the EU (for now), there are no excuses for doing this. no, letting your website be handled solely by marketing heads is not an excuse.
Cockpit is a simpler choice for that.
I would personally use grafana, but zabbix is also a good choice.
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.
