I have worked a litte bit more on the watchdog script.

The scripts gets startet over subprocess.

The subprocesses managed in a dictionary to start/stop/restart

The whole function run in a thread so it dont block the main process and multiple watchdogs can be started.

Outcome is a phyton watchdog script with the following futures:

• Keep an eye on your scripts start/stop/restart them automatically if necessary
• Dont block your main script
• You can start more then one watchdog parallel
• Easy implementation and configuration
• Clean exit over the main process so nor more wild running uboat scripts

I have uploaded everything to github with example files and description.

You can find it here: Python-Watchdog on github

Thanks to everybody !
