Modified oswatchdog
This is a modified version of BlueWall's oswatchdog. I had trouble getting the original to run and it was not well designed for multiple instances (I run quite a few). This allows you to easily add as many instances to be monitored as you wish.
NOTE: This assumes you have separate script(s) to launch each instance and apply any relevant settings, whereas BlueWall's original executed the commands directly from the watchdog script.
Opensim Status
This is the script I use to monitor my Opensim instances and restart them as needed. Originally based on BlueWall's oswatchdog script.
