Modified oswatchdog for multiple instances
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.
