Analyzing Monitor Data › Interactive Analysis Option 9 - USSView

Interactive Analysis Option 9 - USSView

The USSView option displays information about USS activity on a process basis (which is very similar to having a TaskView for USS display).

The USSView panel provides information about delay information by process, code details by process, and process level information. The DelayView and Delay Locations displays include information for all processes. Process level delays would look similar.

If no USS data is in the monitor data set, the USSView option is not available.

The available commands for USSView are described next.

ADDHelp

Invokes the content-sensitive Help application to update or create a help entry for the selected content.

C

(CodeView Detail line command) displays the CodeView Detail panel showing activity detected by CA MAT.

D

(DelayView Detail line command) displays the DelayView Detail panel showing the types of delays encountered by CA MAT.

T

Displays the Thread IDs associated with the selected Process ID.

S

Displays statistics and information about the selected Process ID.

F

Displays the USS Functions associated with the selected Process ID.

Each field in USSView is described next.

Process ID

Numerical Process ID value.

Initial Command

Program (or CSECT) that invoked USS.

If CA MAT cannot determine the program name, This field can be blank.

Activ%

Percentage of the monitored period when a CPU was in use.

CA MAT calculates this value as the ratio of samples in which it detected CPU activity to the total number of samples.

Wait%

Percentage of the monitored period where CA MAT detected USS waiting for resources.

Total%

Sum of the Activ% and Wait% fields.

Visual

Graphical representation of the Total% field.
