Performance Testing using WCAT with example.

WCAT Stress Test Tool

I have tried to run WCAT stress test tool, but its not that easy and straight forward to get the results. Finally I have succeeded to run WCAT tool. Here is the procedure.

1. Download WCAT 6.3  (http://www.iis.net/downloads/default.aspx?tabid=34&g=6&i=1466)

2. Install WCAT tool

3. Create Two files called ‘scenario.ubr‘ and ‘settings.ubr’ in WCAT Tool installed folder ( like C:\Program Files\wcat)

4. Scenario.ubr file content (sample)

scenario

{

warmup   = 30;

duration  = 120;

cooldown  = 100;

transaction

{

id = “test”;

weight = 1000;

request

{

url = “/AAA_ST/Web/Index.aspx”;

}

}

}

5. Settings.ubr file content ( sample)

settings

{

clientfile = “scenario.ubr”;

server = “192.168.102.128″;

clients = 1;

virtualclients = 100;

counters

{

interval = 10;

counter = “Processor(_Total)\\% Processor Time”;

counter = “Processor(_Total)\\% Privileged Time”;

counter = “Processor(_Total)\\% User Time”;

counter = “Processor(_Total)\\Interrupts/sec”;

counter = “Memory\\Available KBytes”;

counter = “Process(w3wp)\\Working Set”;

counter = “System\\Context Switches/sec”;

counter = “System\\System Calls/sec”;

counter = “Web Service(_Total)\\Bytes Received/sec” ;

counter = “Web Service(_Total)\\Bytes Sent/sec” ;

counter = “Web Service(_Total)\\Connection Attempts/sec” ;

counter = “Web Service(_Total)\\Get Requests/sec” ;

}

}

6. Open TWO command windows

7. In FIRST command window type following command:   “wcclient.exe 192.168.128 -b ” where (192.168.102.128 is  your machine ip address)

8. In SECOND command window type following command:  ”"wcctl.exe -t scenario.ubr -f settings.ubr -s 192.168.102.128 -singleip -extended” where (192.168.102.128 is  your machine ip address)

9. WCAT Test will  start and LOG File will created inn WCAT directory
