Re: [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

[Thomas <tlp-hobbit (at) holme-pedersen.dk>]

We do have the same setup in my company. Here I am running a cluster 
agent and 2 "node" agents. The cluster agent then checks only the 
cluster services and reports with the cluster name. Is also located on a 
clsuter filesystem so that it is handles by HACMP to stop/start with the 
ressource group.

in the bb-hosts file if you add conn=worst,1.2.3.4,2.3.4.5 both ips will 
be pinged and alerts will go red if any of the ips are unavailable.
