Sometimes it is necessary for the load test to send a Linux command to verify the content/file exists in the remote Linux server. Every time it is not a fair idea to connect remote server by file server browsers like WinSCP, putty etc… as it is a load test. In such situations, JMETER offers a sampler called ‘SSH sampler’. This sampler is introduced to communicate with the Linux server over the ssh shell. It will be definitely useful for both Functional and Performance Testers.

A sampler which will connect to a Linux server and execute Linux commands
