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.

i use syncthing, and start it via the systems service. i found it reliable. systems has a feature by which you can get notified on error (look up the onerror key), you might be able to do what u need with that.

alternately, you can run a systemd timer that runs periodically and notifies you when your condition is met. if u want a pop-up, use zenity etc.

By systems service you're talking about systemd, right? I found this guide that sets up syncthing as a systemd service. Archwiki has a different one though.
And as the Archwiki alludes to, there's this Syncthingtray tool that can be set up to show notifications.

Yeah, autocorrect isn't great with technical terms. I meant systemd. I followed Arch's instruction, and just enabled the services via systemctl --user enable syncthing.service

I have tried Syncthingtray and Syncthingy. I found the former did too much that I never used, and the latter was an unnecessary process doing very little while always running and adding another icon to the tray. For me periodic checking with a script is enough and more efficient for the rare situation where Syncthing crashes of fails to start.

They do mention a plasmoid for KDE plasma, although according to their documentation that requires distro specific packaging. For Debian it looks like there's a community package (right side).
EDIT:

Doesn't look too busy imo.
