📝 Describe your problem

I think we need an entry in the wiki for maintenance of uptime kuma.

For example I found in ~/.cache/Cypress 1.2GB of files, are they needed? Can they be cleaned up?

Is there a way to clean up unused npm modules to save disk space?

I found a file core.809 (180MB) in my uptime-kuma folder, I assume it is a coredump from a crash. Can we clean these up regularly?

If there are general maintenance tasks, we should perform them not some entry in the wiki.

We tried to compress the npm part, but were not succssfull.
About the other part I don't know => reclassifying as a FR

The coredump should not be deleted, instead it might contain important information why your system crashed (or not, who knows?)

=> consider looking at the crashdump and reporting the results

All the better if Uptime Kuma can clean up cache data by itself!

How does one open the crashdump file? Or is it easier if I just upload it somewhere for you to look at?

Here is a stackexchange article explaining the various options:
https://askubuntu.com/questions/434431/how-can-i-read-a-crash-file-from-var-crash

I would ask you to do the work involved. Ther might be secrets in there you might not want shared/known.
