Measures reported by OVMControlDomTest

When Oracle VM Server for SPARC software is installed, a domain called the control domain is created. From this control domain, you can create virtual machines called logical domains that each run an independent OS. The control domain manages the logical domains and in the process consumes the physical CPU and memory resources of the Oracle VM server. In the event of a resource contention, administrators must figure out what is draining resources from the server – is it the control domain? Or is it one/more of the logical domains on the server? Using this test, administrators can accurately tell whether/not the control domain is contributing to the resource crunch experienced by the Oracle VM server.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Cpu_count Indicates the number of processors assigned to the control domain. Number  
Cpu_utilization Indicates the percentage of physical CPU resources utilized by the control domain. Percent If the value of this measure consistently grows closer to 100%, it is indicative of excessive CPU usage by the control domain.
Memory Indicates the amount of memory used by the control domain. MB Ideally, the value of t his measure should be low.
