I would suggest upgrading to 6.8 or 7.0 in a few weeks.  The updated infrastructure cartridge can take multiple os configurations at a time now vs. scripting something out.
Is there a way to script creating a few hundred OS host agents by pulling host names from a text file or something similar?  i want to start monitoring services for an HIS system we have that is over 400 vms.  to do this manually would be mind boggling.   Thanks in advance as i am sure this has been asked before.  running vfoglight 6.7
