I am using https:///path to send the queries from Jmeter to the application. The FQDN is configured with 2 IPs. I need to know, to which IP my FQDN is resolved for each sample. Can we get the IP to which FQDN is resolved in JMeter listner?

If your server doesn't return its IP address in the response headers or body - you won't be able to get it from the "lisnter" (whatever it is)

However you can get this information from jmeter.log file if you:

  1. Add DNS Cache Manager to your test plan

  2. Enable debug logging for it by adding the next line to log4j2.xml file:

    <Logger name="org.apache.jmeter.protocol.http.control.DNSCacheManager" level="debug" />

This way you will be able to see what are underlying IP addresses behind the system under test domain name

Anyway you will need to add the DNS Cache Manager (or at least disable DNS caching) otherwise you will always be hitting only one IP address which will be cached on JVM level.
