JMeter Distributed Testing Step-by-Step

This short tutorial explains how to use multiple systems to perform stress testing. Before we start, there are a couple of things to check. 1. the firewalls on the systems are turned off. 2. all the clients are on the same subnet. 3. the server is in the same subnet, if 192.x.x.x or 10.x.x.x ip addresses are used. If the server doesn't use 192 or 10 ip address, there shouldn't be any problems. 4. Make sure jmeter can access the server. 5. Make sure you use the same version of Jmeter on all the systems. Mixing versions may not work correctly. [via]
