We monitor our ESX VI3 clusters with OpManager and there seems to be a glitch in the alerting for virtual machines with more than one CPU assigned.

Example:

DatabaseServer01 is assigned 4 CPU and during the course of daily operation, some action causes said CPU's to breach the assigned threshold of 95%.  We receive 4 email notifications about this breach, but only one of them actually contains the VM name:

Message: CPU Utilization of VM for .707 is 96 %, threshold value for this monitor is 95 %Device: remesx01.rem.ctxCategory: ServerError Condition: AttentionGenerated at: Nov 18,2009 10:28:41 AM

Message: CPU Utilization of VM for .705 is 96 %, threshold value for this monitor is 95 %Device: remesx01.rem.ctxCategory: ServerError Condition: AttentionGenerated at: Nov 18,2009 10:28:41 AM

Message: CPU Utilization of VM for .706 is 96 %, threshold value for this monitor is 95 %Device: remesx01.rem.ctxCategory: ServerError Condition: AttentionGenerated at: Nov 18,2009 10:28:41 AM

The same will happen when the alert is cleared.  Is there a particular reason for this behavior?  Do I have something set wrong that is causing this?

Thanks in advance for any feedback.
