Hi,

use SNMP! The latest version of the SNMP Subagent gives you access to
the state of all resources.

Read the README in the subagent dir of the sources. Good documentation
there.

for nagios:

define command {

command_name check_snmp_myCluster

command_line $USER1$/check_snmp -H $HOSTADDRESS$ -o
.1.3.6.1.4.1.4682.1.2.0 -w 2: -c 2:

}


or


define command {

command_name check_snmp_resource_IP

command_line $USER1$/check_snmp -H $HOSTADDRESS$ -o
.1.3.6.1.4.1.4682.8.1.7.1 -w 1: -c 1:

}


There are lots of other things you could monitor. Adjust to your needs.
