I have a basic understanding of Grafana since we use it at work. It definitely fits the question, but it’s also very much overkill for my purposes - maybe not in the range of features, but definitely in scope.

Your mention of dockcheck.sh is gold! Someone else mentioned diun, but I think this shell script is even better. As long as there’s a simple way to determine which containers use outdated images, I’m good. The metrics part can be solved with a tool like Beszel or I can whip something up myself if I don’t find anything good enough.

Thanks for your reply. I like Cockpit, it not only looks appealing but also seems to be just the kind of tool I’d love to use. Since I don’t have a need for its current feature-set though, I’ve starred the project on GitHub and will keep an eye on it as it develops.

diun for update notifications and Beszel for the dashboard look pretty good and lightweight. I’ll definitely test then to see how well they suit me. Thanks!
