Inspect Address Space CPU Use workspace

The information in the Inspect Address Space CPU Use workspace allows you to observe where in the executable code a z/OS address space is spending its time. This workspace contains three views:

Accessing the workspace
About the Inspect links
Using custom inspect parameters

Accessing the workspace

You can link to the Inspect Address Space CPU Use workspace using one of two predefined links from the Address Space CPU Utilization table in the Address Space CPU Utilization workspace. When you select the link for a particular address space, the Inspect workspace is populated with data gathered using the parameters specified in the link definition.

The workspace is not populated by data until the Inspect agent completes on the host system. The time it takes to complete is a function of the number of samples and the sampling interval. For example, if 1000 samples are take at a 5-millisecond interval (the default settings), it will take 5 seconds for the data collection process to complete.

There are two Inspect links:

Using custom inspect parameters

Note:
The changes you make to the Inspect link cannot be saved unless you save and rename the workspace using Save As. They are deleted when you close the Inspect workspace.

When you are selecting the values for number of samples and the sampling intervals, bear in mind that if the total time taken to execute the agent exceeds the client timeout value in the Tivoli Enterprise Monitoring Server, the Tivoli Enterprise PortalTivoli Enterprise Portal will return no data, even if the agent subsequently completes normally.

To modify the Inspect with custom parameters link:

  1. Navigate to the Address Space CPU Utilization workspace by linking from the Address Space Counts table of the Address Space Overview workspace for the target system.
  2. Right-click the Artwork for kg0084alink icon beside a row in the Address Space CPU Utilization table and select Link Wizard from the pop-up menu. The Link Wizard editor appears.
  3. In the Selection area, select Inspect with 5000 samples at 2ms interval, then click Next >.
  4. In the Link Identity field, type a new name for the link and a description, if desired, then click Next >.
    Note that changing the name of the link will change its name in the link pop-up menu.
  5. In the Properties tree, select the Artwork for kg0109INTERVAL symbol under Query - Inspect Address Space CPU Use. The Expression editor appears instead of the help in the right frame.
  6. In the Expression field, type the interval, in milliseconds, at which you want Inspect to collect samples.
  7. In the Properties tree, select the Artwork for kg0109SAMPLES symbol under Query - Inspect Address Space CPU Use.
  8. In the Expression field, type the number of samples you want Inspect to use in deriving the data.
  9. Click Finish to save your changes and close the editor.

The new name is displayed in the pop-up menu when you right-click a link icon in the Address Space CPU Utilization table.
