Duna Watchdog

Brief description

It opens the apps configured in etc/duna.xml, each one inside a new screen session. Then it checks if these apps are alive, warning by mail when one of them crash/end/close. When that happens, DunaWatchdog try to restart the app.

If one app cannot start/restart, DunaWatchdog also warns about it by email. Additionally you can tell DunaWatchdog to restart an app if it have reached a certain memory percentage.

DunaWatchdog logs are generated automatically and screen logs can be enabled for each app inside etc/duna.xml.


  • Install software: mutt msmtp screen
$ git clone
$ cd dunaWatchdog
$ ./
  • move/rename the portable folder wherever you want. It is all you need.
  • Edit portable/etc/msmtp.conf with your gmail user and password. Any mail configuration can be used configuring msmtp.conf properly (see man msmtp)
  • Edit duna.xml adding the apps you want to watch. Also you can change the global time parameters at top for your own needs.
