You can troubleshoot any Data Center Operation: PRO Pack issues in the Event Viewer Application log.
Type of events that you might see:
Why don't I see all my virtual machine hosts in the list in Microsoft System Center Operations Manager?
- The list of virtual machine hosts is not a complete list of all hosts monitored in Microsoft System Center Operations Manager. It is a list of those that have been associated with modeled objects in Data Center Operation.
- Data Center Operation: PRO Pack retrieves data from Data Center Operation at a specified polling interval. If you do not see all the virtual machine hosts that you expect to see, wait for the specified period of time and the view will be updated with the latest data.
- Discovery: 4 hours
- Monitoring: 30 seconds
I get many reports of impacted virtual machine hosts. What could be the cause of this?
Ensure the configuration represents the real-world physical environment as accurately as possible. For example, the system will reflect the real-world more accurately if you configure power connections all the way down to the server level than if you stop at the rack PDU level. If the system is missing the server connection data, it will use the information available. It will report more impacts because it does not know which servers are connected to which rack PDUs.
- If a rack PDU in a rack is critically impacted by an alarm, the system will assume that all servers are connected to that rack PDU are impacted by the alarm.
- If there are two rack PDUs in a rack, the system will assume that all servers with redundancy are connected to these two rack PDUs are impacted by the alarm.
Virtual Machine Manager does not migrate virtual machines to a host. What could be the cause of this?
If a host outside a cluster was previously impacted, Data Center Operation: PRO Pack changed the status of this host from available for placement to unavailable. Once you have resolved the issue and the host is healthy, you must make it available again: In Virtual Machine Manager, right-click the host in Virtual Machines> Host Groups, select Properties> Status, and select This host is available for placement.
If you are integrating with Virtual Machine Manager 2012, your setup may look a little different from the instructions and images in this user assistance since these have been created for integration with Virtual Machine Manager 2008 R2.
