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.

# Add a new line for each instance you want to monitor.
# All you need to do is replace each of the three settings with the correct
# values for the instance.
#
# status_check "<listener port>" "<screen name>" "<launch script>" "<user>"
#
# <listener port> - The port the instance listens to. Is set in OpenSim.ini; default is 9000
# <screen name> - The name of the screen running the instance
# <launch script> - The filename of the script that launches the instance
# <user> - User that opensim runs under. Unless you set RUN_AS_OTHER_USER='TRUE' this will be ignored
#
# Example: status_check "9000" "OpensimOne" "/home/opensim/opensim-one.sh" "opensim"
