Monitor resources and workloads across LPARs

OMEGAMON XE on z/VM and Linux provides information about the overall utilization of resources by the logical partitions (LPARs) defined for your system.

You can use the LPAR workspace to determine when to move resources from logical partitions with less important work to logical partitions with more important work when that work is missing its goals.

Use the LPAR Utilization table in the LPAR workspace to determine how well each logical partition is able to obtain CPU resources. This table provides data about overall system utilization by each of the defined logical partitions. The table shows data such as the total amount of time that all of the logical processors for a logical partition were busy during the collection interval, the percentage of elapsed time that a logical processor spent to manage LPARs, and the utilization of the system based on the number of logical processors available.

The Processor by LPAR Name workspace, which is accessed from the LPAR Utilization table of the LPAR workspace, displays data about the logical partitions for which you elected to view additional information. Use this workspace to determine the resource usage by specific logical partitions and the load for each of the defined processors.

Additionally, the Processor by LPAR Name workspace provides data about overall system utilization by each of the defined logical partitions. The table shows data such as the total amount of time that all of the logical processors for a logical partition were busy during the collection interval, the percentage of elapsed time that a logical processor spent to manage LPARs, and the utilization of the system based on the number of logical processors available. This workspace also provides data about the types of processors being used. Use this workspace to determine how well each logical partition is able to obtain CPU resources.

You can also use the CPC workspace to see the total usage of your processors across LPARs, by processor type. You can use this workspace to determine if you need to add additional processors, such as IFL (Integrated Facility for Linux) processors, or if your current processors are underutilized and therefore can handle additional capacity. The Scaled Overall LPAR Busy Percent view shows, by processor type, what percentage of your CPU is used. The Processor Busy by Count of Processors view shows, by processor type, the amount of processing capacity that is used. The amount that is shown represents the equivalent of the total number of processors that are busy.
