User's Manual

NOTE: With the HP Serviceguard A.11.20 release, application monitoring is now supported
for VM guests that use online VM guest migration. It is not supported with the HP Serviceguard
A.11.19. To support online VM guest migration, all service command strings sent to the VM
guest must be unique. This means, if two instances of the same application are started and
monitored in the VM guest using cmappmgr, the service strings must be different, even if a
space needs to be added to one of them.
6. Test application monitoring and VM guest failover operation.
After VM guest application monitoring is configured, you must test application restart and VM
guest failover by terminating the monitored application on the VM guest and verifying:
• The SERVICE_RESTART counter for the cmappmgr SERVICE_CMD used to monitor the
application increases.
• The VM guest fails over to a standby VM Host node after the SERVICE_RESTART value
exceeds.
Example of Configuring application monitoring service
# cmdeployvpkg -P slvm1 -x merge -x appmon
