Address Space CPU Utilization workspace
This workspace provides information about CPU utilization by address space
for all address spaces in this LPAR. The workspace contains a table view and
bar chart that illustrate the CPU utilization for each address space on the
selected system.
The name of the system being reported on is found directly below the table
view within the workspace. For each address space, the table view displays
basic identifying information such as job name and address space ID, basic
Workload Manager information such as service class and service class period,
and various CPU statistics. It also provides enclave data, such as the total
number of dependent and independent enclaves owned by the address space that
are currently active or inactive.
The CPU Usage bar chart shows the CPU percentage, TCB percentage, and SRB
percentage for each job listed in the workspace's table view. (The bar chart
does not reflect enclave CPU utilization. For enclave CPU utilization, see
the Enclave Information workspace.)
From the Address Space CPU Utilization table, you can navigate to the
- Enclaves Information workspace, to view
just those enclaves owned by a particular address space
- WLM Service Class Resources workspace, to
view service class period information for the service class and period in
which the selected address space is executing
- Address Space CPU Usage Details workspace
- Address Space CPU Usage Enclaves workspace
- Inspect Address Space CPU Use workspace,
to see data drilled down to the CSECT level of data for the most active TCBs,
for a selected address space.
The help for the Inspect Address Space CPU
Use workspace contains information on the Inspect function, the default links,
and customizing the Inspect parameters used to collect the data in the workspace.
There are two links to the Inspect Address Space CPU Use workspace:
- The Inspect Address Space CPU Use link uses the default parameters of
1000 samples at 5 millisecond intervals to collect the data presented in the
workspace.
- The Inspect with 5000 samples at 2ms interval link uses the specified
parameters, but it can also be modified to use the sample count and sampling
interval you specify to collect the data to be presented in the workspace.
- The IBM Tivoli OMEGAMON XE for CICS on z/OS Region Overview workspace
for the selected address space.
Note:
The OMEGAMON XE for CICS
monitoring agent must be installed and running on the target system for the
link to be functional.
You can link to the Address Space CPU Utilization workspace from the following
locations:
- The Address Space Count view of the Address Space
Overview workspace
- A row of the Enclave Information table view in the Enclave Information workspace to see information related to the address
space owning the navigated-from enclave.
- A row of the WLM Service Class Resources table view in the WLM Service Class Resources workspace to see information related to those
address spaces executing in the service class and period of the navigated-from
row of the WLM Service Class table view.
