JMeter - Iterate the Remote Commands over a csv file - jmeter

Question

I need to simulate the below via JMeter:
1. Launch Putty.
2. Enter the IP Address.
3. Login
4. Execute a command. This command needs to be iterated over a csv file.
Unsure of point number 4. especially the iterating part.
Please help.
Regards,
Ajith

Answer 1

Execute a command - take a look at OS Process Sampler
This command needs to be iterated over a csv file - take a look at CSV Data Set Config
If you CSV file looks like:
command1
command2
command3
The following CSV Data Set Config setup:
will read the command from the file and save it to ${command} JMeter Variable, the variable will be updated for next iteration of next thread (virtual user)

Answer 2

You can use beanshell sampler to run commands from your native terminal. Beanshell is just java. You can write all your java code to open a terminal to run your commands. To read data from csv you can use jemetr CSV Data set config.
Sample test.csv file:
a,b,c
x,y,z
p,q,r
Sample beanshell commands to show how you can read data from csv to parametrize your commands: ${a} and vars.get("b") both will work.
log.info("${a} - - - - "+vars.get("b"));

You can also use selenium autoit to run your commands as manual simulation with selenium web driver plugin.
