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 Address Space CPU Utilization 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 link to the
- Enclave 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.
- OMEGAMON for MVS - Job Details
workspace for information about the job
in the selected row.
- 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 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.
