[hobbit] I'm starting to look at setting up 'propr' monitoring for my production SAP environment, and wonder if anyone else is playing with HACMP clusters

Hi Tom,

Not the same but similar. We have 1-3 virtual hosts on each machine. 
There is only one hobbit client installation but one instance running 
for each host on all machines. Custom scripts differ for these hosts. 
 From serverside we treat them as different machines so e.g. disk is 
surveyed completely for all hosts. But you could easily disable the 
normal disk test and replace it by a custom script which greps for the 
interesting partitions.

kind regards
Rolf
