Use the WLM Service Class Resources table view to determine how well your defined service classes are performing against the goals you have set for their performance. Use the Performance Index to see how well services are meeting their goals.
In addition to the table view, the workspace contains three bar charts that illustrate the information provided in various columns of the WLM Service Class Resources table view:
The CPU Percentage bar chart permits you to determine those jobs that are consuming the largest percentage of processing time and to compare the processing time consumed by given jobs.
The I/Os per Second bar chart illustrates the contents of the I/O Rate column in the workspace's table view. This bar chart permits you to determine which jobs are performing the largest amount of I/O and to determine those jobs that are responsible for excessive I/Os.
The Average Storage Use in Bytes chart illustrates the contents of the Average Storage column in the table view and permits you to see at a glance the amount of storage consumed by a given job.
You can link to this workspace from a row in the Enclave Information table view in the Enclave Information workspace. In this case, information is displayed for the service class period in which the navigated-from enclave is executing.
From a row in the WLM Service Class Resources table view, you can navigate to
a workspace to view summary information about the bottlenecks that are occurring for the selected service class period
a workspace that contains information about those enclaves executing in the selected service class and period
a workspace to view the CPU utilization of those address spaces executing in the selected service class and period
This workspace can record history.
