=== Modified oswatchdog for multiple instances ===
+
== Opensim Status ==
This is a modified version of [[User_talk:BlueWall#oswatchdog|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.
+
This is the script I use to monitor my Opensim instances and restart them as needed. Originally based on BlueWall's oswatchdog script.
  
'''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.

[edit] 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.

NOTE: This assumes you have separate script(s) to launch each instance
