Sometimes you might have a situation where all of your agents are showing as healthy in the console but when you try and draw a performance report data is missing.
The below SQL query which has been developed by my colleague Gerrie Louw will identify any agent that has not submitted performance data in the past 4 hours. It does so by checking the following performance counters:
Processor > % Processor Time
LogicalDisk > % Free Space > C:
Memory > Available MBytes
Note: You will probably have to change the DisplayName_ and IsVirtualNode for your OperationsManager database.

You can use this query to build a report such as the one sampled below:
