hello,
I am new to jmeter. i have downloaded and installed it properly.
i gone thorough the documentation and performed the stress testing of my website

#-Link-Snipped-#
I have done the following steps

1. added a thread group
in this a) no.of threads (users) 1
b) Ramp-up period 5
c) Loop count 2
2. added HTTP request defaults ( added in thread group)
server name or IP : #-Link-Snipped-#
port no 80
3. added logic controller -->loop controller
loop count : 8
4. In Loop controller
added 5 sampler-->http request (to different pages of my website e.g
path : /index.php
path : /course/enrol.php?id=68)
5. added 4 listerners i.e add graph full results ,view result tree, view

result in table, monitor result to thread group
6. then i run this using run menu

site is running properly
