226 IBM Tivoli OMEGAMON XE V3.1 – Deep Dive on z/OS
6.6 IBM Tivoli OMEGAMON XE on z/OS new features
This section illustrates some of the new features that are available with IBM Tivoli
OMEGAMON XE on z/OS V3.1.0. The discussion includes use of the INSPECT
function, followed by 6.6.2, “Reviewing work running on a zAAP processor” on
page 229.
6.6.1 Using the INSPECT function with Tivoli Enterprise Portal
The INSPECT function from the OMEGAMON for MVS classic and CUA 3270
implementations has been migrated to the OMEGAMON environment. This
function samples the location of the instruction address register in the target
address space on a rapid basis for a relatively short period of time. This enables
it to build up a profile of which instructions, which programs, and which tasks are
consuming CPU resources in the address space. This information can help you
identify inefficient code, or where in an address space code may be looping.
In our scenario we investigate the Tivoli Enterprise Monitoring Server address
space running on SC67 LPAR.
The INSPECT function is available from the Address Space CPU Utilization
workspace. To get to the Address Space CPU Utilization workspace, use the
Address Space Overview workspace, which is located in the Navigator tree
shown in Figure 6-28.

Chapter 6. Working with Tivoli Enterprise Portal 227
The Address Space CPU Utilization Summary is linked from the Address Space
Counts portlet as shown in Figure 6-2 on page 195. Right-click the Address
Space Count link and select Address Space CPU Utilization.

The Address Space CPU Utilization workspace shows a list of running address
spaces. Right-click an address space to inspect it (in our case CANSDSST), as
shown in Figure 6-30. Select Inspect Address Space Cpu Use.
