Within a schedule, you set the size and sampling rate of the test
log and the problem determination log, as well as the statistics that are
displayed during a run.
Setting the statistics displayed during a run You can set the type of data that you see during
a run, the sampling rate for that data, and whether data is collected from
all users or a representative sample.
Setting the data that the test log collects The test log shows the events that occurred during
a run. By setting the level of information that is collected for a schedule
run, you can control whether you receive individual response-time statistics
for Percentile reports and information about verification points. You can
set the level of detail for each type of event: errors, warnings, and other
events.
Setting the problem determination level You can
set the level of information that is saved in the problem determination
log during a run. By default, only warnings and severe errors are
logged. Typically, you change this log level only when requested to
do so by IBM® Software Support.
