I am currently using Jmeter v5.2 for Remote Testing and trying to connect to the slave. Followed all steps from Jmeter user manual. At the end i could not see the results in my master machine and i am getting below error.

System property 'java.rmi.server.hostname' is not defined, using localHost address

I believe i have crossed check if any mistake from my side, like

  1. Both Running on same version of Jmeter and Windows
  2. Ensuring nothing is listening on the Port

but yet no luck. Is there anything i am missing on? Also at the server side(slave) i get message as follows. enter image description here

Which looks like the connection is successful. But i do not see any results.
Below are the jmeter logs

First of all check jmeter-server.log file on JMeter slave machine, in case of failure it should contain enough troubleshooting information so you will be able to get to the bottom of the issue.

Second, looking into jmeter-server file there is a stanza which looks like:

# If the client fails with:
# ERROR - jmeter.engine.ClientJMeterEngine: java.rmi.ConnectException: Connection refused to host: 127.0.0.1
# then it may be due to the server host returning 127.0.0.1 as its address 

# One way to fix this is to define RMI_HOST_DEF below
#RMI_HOST_DEF=-Djava.rmi.server.hostname=xxx.xxx.xxx.xxx

So you can try explicitly setting the RMI server hostname on JMeter slave(s) side like:

jmeter-server.bat -Djava.rmi.server.hostname=10.20.30.40

once done you can launch JMeter master like:

jmeter -R10.20.30.40

Replace 10.20.30.40 with the actual IP address of your JMeter slave machine.

  • Thanks for the Reply. I tried with explicitly defining the Rmi server hostname as shown, but no luck. I again see same error in the logs (updated my question with logs). Am i still missing on anything? Kindly help. – Vishal Chepuri Nov 18 '19 at 14:42

I have solved it by increasing the retry count, which was by default 1. When distributed test is starting, there may be several attempts to initialize remote engines
You can find and edit "client.tries" in jmeter.properties file and Uncomment as

client.tries= 3

Also i have used below command to start the jmeter server in slave machine.

jmeter-server.bat -Djava.rmi.server.hostname=local ipaddress

Which helped me explicitly define rmi server hostname to local address.
