Measurement
Unit |
Interpretation |
| Cpu_util |
Indicates the percentage of physical CPU resources utilized by the control domain or the Solaris host.
|
Percent |
This measure clearly indicates where resource-intensive processes are executing - on the Solaris host or on the control domain?
If the processes executing on the control domain or on the Solaris host erode the physical CPU resource-base, it is bound to affect the resource allocations to the other guest domains, and ultimately impact the performance of applications executing on those guest domains.
Use the detailed diagnosis of this measure to determine the top CPU-consuming processes on the control domain or on the Solaris host, and kill rogue processes to ensure optimal CPU usage.
|
| Virtual_cpu_util |
Indicates the percentage of allocated CPU resources that the control domain has utilized.
|
Percent |
A very high value for this measure indicates excessive CPU utilization by that processor supported by the control domain. The CPU utilization may be high because a few processes are consuming a lot of CPU, or because there are too many processes contending for a limited resource. If adequate CPU resources are not available to the control domain, then the applications executing on the domain will experience slowdowns.
To check whether resource-intensive processes are executing on the primary domain, use the detailed diagnosis capability of this measure; this will list the top 10 CPU consumers on the control domain.
Note that this measure is available only for the Primary descriptor of this test.
|
| VCpus_allocated |
For the Primary descriptor, this indicates the percentage of CPU resources allocated to the control domain. For the Total descriptor, this measure indicates the percentage of CPU resources allocated to other guest domains on the Solaris host.
|
Percent |
The values of these measures is a clear indicator to whether the hypervisor has over-allocated or under-allocated CPU resources to the domains.
|
| Number_of_vcpus |
For the Primary descriptor, this indicates the number of CPUs allocated to the control domain. For the Total descriptor, this measure indicates the number of CPUs allocated to other guest domains on the Solaris host.
|
Number |
| Memory_allocated |
For the Primary descriptor, this indicates the physical memory size allocated to the primary domain. For the Total descriptor, this measure indicates the total physical memory that is allocated to other guest domains on the Solaris host.
|
GB |
The value of these measures indicates how efficiently the hypervisor has allocated memory resources to the control domain and other guest domains. These values also enable administrators to figure out if the Solaris LDoms server is adequately sized in terms of memory resources to handle the load imposed by the logical domains.
|
| Memory_alloc_percentage |
For the Primary descriptor, this indicates the percentage of physical memory allocated to the primary domain. For the Total descriptor, this measure indicates the percentage of physical memory that is allocated to other guest domains on the Solaris host.
|
Percent |
|
| Total_memory |
Indicates the total memory on the Solaris host.
