From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there a simple GUI application alerting the user when a process is not running? (lemmy.ml)

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.

Hello! I don’t know of a desktop watchdog application that will do this for you, but you may be able to achieve this with a simple cron job. Probably just an hourly crontab entry that looks for a running process with the right name, and uses something like notify-send to send an alert if it’s not found. I’ll jump on the computer and have a quick play, though I run gnome not plasma so I don’t know how well it will translate.

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/0

I imagine dbus-monitor should work with cron but probably if starting once DBUS is actually running (so not sure @reboot would be sufficient)
