How can I get the Ip address of server from which response is coming?

Question

I'm a newbie to JMeter currently, I'm testing a Rest API, I need to record the server IP from which the response is coming.

I'm able to test the API but not able to record the IP address. How can I achieve the same?

Assuming you send to server name in variable serverName, so add JSR223 PostProcessor (or other JSR223 element) and get the IP using InetAddress:

This class represents an Internet Protocol (IP) address.

InetAddress address = InetAddress.getByName(vars.get("serverName")); 
log.info address.getHostAddress();
vars.put("serverIP", address.getHostAddress());

You can then use ${serverIP} variable

Add JSR223 PostProcessor as a child of the HTTP Request sampler

Put the following code into "Script" area:

log.info('Source IP address: ' + InetAddress.getByName(sampler.getDomain()).getHostAddress())

It will print the IP address to jmeter.log file

If you want to save this IP for later re-use you can amend the code like:
```
vars.put('ip', InetAddress.getByName(sampler.getDomain()).getHostAddress())
```
and add the next line to user.properties file:
```
sample_variables=ip
```
As a result you will have an extra column in .jtl file containing IP address of the server.
