Hi Guys, As per earlier discussion & suggestions on Distributed Load testing to achieve Max concurrency, I've configured my jmeter set up on aws server per this link https://www.blazemeter.com/blog/how-to-perform-distributed-testing-in-jmeter
But still my master is unable to connect to slave machines . getting *connection time out error *always whenever Master tries to connect to Slave. Configuring remote engine: 10.30.x.x (slave ip) ERROR org.apache.jmeter.engine.DistributedRunner - Failed to create engine at 10.30.x.x ( Slave ip) java.rmi.ConnectException: Connection refused to host: 10.30.x. x ; nested exception is: java.net.ConnectException: Connection timed out (Connection timed out) Configuring remote engine: 10.30.x.x Connection refused to host: 10.30.4.210; nested exception is: java.net.ConnectException: Connection timed out (Connection timed out) Failed to configure 10.30.x.x *Let me give a brief of what I have done* 1. Got 5 more aws slave instances & *all instances are replicas of Master instance *having same Jmeter & Java & Jenkins version of Master instance . 2. All slave & master instances are on same subnet. 3. In jmeter.properties file of Master Server , added IPs of all the slave systems against remote_hosts property. 4. Started jmeter.server file on all slave instances by running cmd *./jmeter-server *& used another alternate cmd too *./jmeter-server -Djava.rmi.server.hostname=10.30.x.x. ( Slave IP)* *Output on running both cmds -> *Created remote object: UnicastServerRef [liveRef: [endpoint:[10.30.x.x:37279](local),objID:[ae7eac4:169775d4503:-7fff, 7214156034065384624]] 5. Passed param in non gui mode in script as -R slave 1, slavve 2 from Master Server ./jmeter -n -t /var/lib/jenkins/workspace/apache-jmeter-4.0/extras/deployjmeter/throughput.jmx -R 10.30.x.x 6 Although I'm starting Jmeter in non gui mode as shell script inside Jenkins but on directly running via cmd line too -- I'm getting connection Timeout error. *Can you guys let me know the mistake or steps I'm missing i.e.* -- Do I have to start jmeter-server on Master Server too ? -- Any port or network connecting issue among Master & Slave ? -- further changes to be done in any file of Master or Server ? -- Is it because Slaves are replicas of Master Instance having same jmeter & jenkins version ( but differ in terms of IP ) -- ::DISCLAIMER:: ---------------------------------------------------------------------------------------------------------------------------------------------------- This message is intended only for the use of the addressee and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
