Monitor processor usage at the system level
Use the Workload workspace to monitor high CPU utilization by the Control Program as well to find out which z/VM® workloads are consuming the most resources.
This table provides information about the total number of CPU seconds used by each workload, the percentage of total CPU used by the z/VM Control Program (CP) to manage the workload, and the total time each workload or each aggregation of the group was logged on. This workspace also contains a bar chart that identifies the five biggest users of CPU. Additional bar charts on this workspace show page read/write data, page rate data, and working set size data.
When you determine that a problem is not originating from z/VM, you can access the Linux Workload workspace to examine the performance of the Linux® guests. The Linux Workload workspace provides data about system usage by user ID for all Linux guest systems defined in your environment. The predefined workspace contains the Top 5 CPU Linux Guest Systems bar chart that displays the top five Linux guest users of CPU. For each Linux guest, it shows the percentage of CPU used by the system to manage the workload, and the percentage of virtual CPU utilized.
The ApplData workspace, also accessed from the Workload workspace provides extensive metrics about network utilization, CPU usage, and operating system data for each Linux guest system.
