A WCAT log file begins with a file header that identifies the attributes of the test run, including the test date and time and the input and output files used. The following example shows the file header of the sample log file, 1ktest01.log:
| WCAT Version | = 3.1 |
| ConfigFile | = scripts\1ktest01.cfg |
| ScriptFile | = scripts\1ktest01.scr |
| DistribFile | = scripts\1ktest01.dst |
| PerfCounterFile | = scripts\server.pfc |
| LogFile | = scripts\1ktest01.log |
| Author | = |
| Creation Date | = |
| Test Run Date | = Mon Dec 02 14:11:00 1996 |
| Comment | = Configuration For File Size Mix |
| Server [IpAddr:Port] | = webserver [webserver:80] |
| Clients | = 1 |
| Threads | = 5 |
| Buffer Size | = 131072 bytes |
| Duration | = 300 seconds (Warmup 30 seconds, Cooldown 30 seconds) |
The following table lists and describes the fields in the log file header.
Table 3 Log File Header Fields
| Field | Description |
| WCAT Version | The version number of the WCAT application used in the test. |
| ConfigFile | The path and filename of the configuration input file used in the test. |
| ScriptFile | The path and filename of the script input file used in the test. |
| DistribFile | The path and filename of the distribution input file used in the test. |
| PerfCounterFile | The path and filename of the performance counters input file used in the test, if any. If the -p option was not used in the test, no filename appears. |
| LogFile | The path and filename of this log file. |
| Author | The author of the test. This field is optional. |
| Creation Date | The creation date of the test. This field is optional. |
| Test Run Date | The date and time the test began. The test reads the date and time from the controller computer. |
| Comment | The text entered in the Comment field in the configuration file for the test. |
| Server [IpAddr:Port] | Server is the name of the server computer used in the test. IpAddr is the computer name or IP address of the server used in the test. The value of this field reflects the value used with the config command on the controller when WCAT was installed. Port is the TCP port on the server computer that is used by Internet Information Server for the HTTP (WWW) Service. The default TCP port is 80. To view or change the TCP port, edit the TcpPort value entry in the Registry. For more information about TcpPort, see Regentry.hlp, a Help file about the Registry on the Supplement 1 CD-ROM. |
| Clients | The number of client computers used in the test. The Clients value reflects the entry in the NumClientMachines field of the configuration file, unless the value was overridden by using the -m option with the run command. |
| Threads | The number of virtual clients run on each client in the test. Each thread in the WCAT process represents one virtual client. The Threads value reflects the entry in the NumClientThreads field of the configuration input file, unless the value was overridden by using the -t option with the run command. |
Table 3 Log File Header Fields (Continued)
| Field | Description |
| Buffer Size | The size of the receive buffer of the memory cache used in the test, in bytes. You can enter a suggested maximum size for the receive buffer in the MaxRecvBuffer field of the configuration input file. |
| Duration | The total elapsed time of the test, in seconds, including the length of the warmup and cooldown periods of the test. The Duration value reflects the entries in the Duration, WarmupTime, and CooldownTime fields of the configuration input file. You can override the value of Duration by using the -u option with the run command. |
