Now let us know the concepts of Jmeter inorder to go further.
JMeter is a open source tool we can download from the site Apache Jmeter.
Jmeter is a performance tool used for finding the avg. response time, devaition etc parameters like the other tools load runner. The only use of the Jmeter is a open source and also it is a less memory eater when compared to the other tools.
NOW create a test plan according to the manual given in the Apache Jakarata site site itself, After creating a test plan save the file with desired name. LETs go to STAF now.
IF for suppose this file is in the remote system. we can execute this file and and the results can be obtained in our systems. INORDER to do this we have to give the trust levels to the remote systems. There are 5 trust levels, according to each trust level the access is differnet for the remote systems. After giving the trust level. Now we can execute the test plan by making a batch file.
In this Batch file we need the controller where the system we handle load generators where the test case is present, Well, i will make batch file very simple to understand and an idea how to execute the test plan by using the batch file.
REM set the controllers
REM set the load generators
REM set the plan
SET controller= webserver1
SET load = webserver2
REM checking the STAF connecting to the remote systems
FOR %%H IN (%controller% %load%) DO STAF %%H PING PING
REM executing the test plan using jmeter
for %%H IN (%load%) Do staf %%H PROCESS START SHELL COMMAND C:\jmeter\bin\jmeter-n.cmd C:\jmeter\bin\myplan.jmx
REM copying the results from the remote system to our system
for %%H IN (%load%) Do staf %%H fs copy directory c:\jmeter\bin todirectory c:\logs\ tomachine %controller% EXT log CASEINSENSITIVE
This is a small batch file where we can use staf and make wonders.
