[Pacemaker] SNMP/SMTP alerts on move or STONITH?

[Simpson, John R]

Dr. Schwartzkopff,

    Thank you for your reply.  I am using the -S / --snmptraps option
with ClusterMon (crm_mon) and I receive traps for start, stop and 
monitor.  I do not receive traps for move or STONITH, which seem more
critical from a data center ops standpoint.

    Zabbix looks interesting -- we currently use Zenoss.
