Is there a simple GUI application that will monitor running processes periodically and alert the user when a process is not running? The ones I have found are far too complex (eg Monit). I am sure this is trivial to achieve with a script, but I’d rather use a GUI.
A use case would look like this: every 60 minutes check if Syncthing is running and display a notification if it’s not. In my experience, Syncthing is very reliable when it launches successfully but there may be an issue with conflicting versions that may prevent it from running at boot. Syncthing has no way to alert the GUI user when something goes wrong and you may find after you left home that your laptop hasn’t synced. Checking manually is a headache, prone to errors and goes against the idea of fit and forget.

It doesn’t work for me (using plasma). Also it seems to be using DBUS which I am not sure if it will work within a cron job.
A simple solution that works for me is something like this:
echo hello > /dev/pts/0I imagine
dbus-monitorshould work withcronbut probably if starting once DBUS is actually running (so not sure@rebootwould be sufficient)Oh very neat, that works great! A much better solution.
Good call on DBUS. Setting XDG_RUNTIME_DIR seems to be enough to fix it up, I’ll update my other response.
