11.1 Observation session request definition
We need to monitor all steps of the TRADERB batch job with the following characteristics:
A sampling rate of 1000 samples per second for all its duration.
TRADERB has a single step.
The measurement file has to be retained for 30 days.
CHABERT has to be notify at the end of the measurement.
By entering the NEW command line on the Observation List (R02) panel, Application
Performance Analyzer will display the Schedule New Measurement (R03) panel. The settings
required to monitor the TRADERB job are shown in Figure 11-1.

When pressing Enter to submit the previous definition, Application Performance Analyzer
displays the Observation List (R02) panel with our measurement definition at the top of the
list, as shown in Figure 11-2.

We now start the TRADERB batch job and check which status has the measurement request
number 4790.
Figure 11-3 shows that the request’s status is active when the job runs.

Figure 11-4 shows that the request’s status is Ended when the job is ended.

Tip: We have 71 562 samples. Because our sampling rate has been defined as 1000
samples per second, we can easily deduce that TRADERB ran 71 562 milliseconds.

The have details on the measurement request and on the sample file created just before, we
can use the “++” line command on request number 4790. Application Performance Analyzer
displays the pop-up shown in Figure 11-5 and Figure 11-6.

When pressing PF8 to scroll down, Application Performance Analyzer displays the last
details, as shown in Figure 11-6.

Details include, but not only:
Session start time and end time
Session duration
Session delete date and time
Sample interval
Samples requested and samples done
Data extractors status.
We use the R line command on request number 4790 to launch the associated Performance
Reports, as shown in Figure 11-7.
