I don't really know what the calendar-resource Nextcloud plugin does, but it seems after installation, you may have to use the occ tool. This is described at https://docs.cloudron.io/apps/nextcloud/#running-occ-tool
I think there was a task to integrate better with prometheus or grafana but it got lost. Let me check if we want to do this for 7.2
@timconsidine Thanks, that is good to hear. I think it is quite natural when somebody discovers Cloudron to go wild installing things to try them and that takes quite a lot of RAM.
One other benefit of smaller applications is that there are often fewer lines where bad code could hide or where things could go wrong.
