I have a webapp to be tested. The current configuration is with 4 API servers with hash method as load balancer.

    upstream example{
      hash $remote_addr consistent;
      server abc;
      server def;
       ---
       ---
}

While performing the load testing, im observing its hitting only 1 server and not all 4 servers. I also tried using load balancer methods as "ip_hash","round robin" and "sticky cookie srv_id;" as i have server with nginx-plus but the application is not working as it needs persistent server for completing 1 user session (uses sticky session).

Is there any way to distribute the load to all servers? Or Am I missing out something Kindly help me.

Try adding a DNS Cache Manager to your Test Plan, it might be the case JMeter is caching the IP address of the one server and doesn't resolve it on subsequent iterations.

  • thankyou. I have added DNS cache manager, but still the load is going to only one server. I tried with distributed load generators aswell but still the same. Kindly suggest if there is any other solution – prasanna Jun 10 '22 at 08:43
