Analyzing the WCAT Log

WCAT records and collects statistical data from the WCAT clients and server during a WCAT test. At the conclusion of the test, WCAT summarizes the data and writes it to an output log file. Data collected during the warmup and cooldown periods of the test are excluded from the log.

WCAT uses the name of the test as the name of the log file in the format testname.log. For example, the log of the Cgi25 test is named Cgi25.log.

The WCAT log is composed of five sections:

· File header

· Results

· Performance counters

· Files

· Class statistics

The performance counters section appears only if the WCAT test was run with the -p option. For more information running WCAT with the -p option, see “Using Performance Monitor Counters in a WCAT Test.”

Tip

Look at the sample WCAT log file included with WCAT for reference while you read the following sections. The sample log file, 1ktest01.log, appears on the Supplement 1 CD-ROM. You can use any text editor or word processor to view the 1ktest01.log file.
