Telnet using JMeter 3.3

I am using Jmeter 3.2 and I need to do a telnet connection and parse the response.

Is it possible using Jmeter 3.2 or adding any plugin?

What I need to achieve is what I would do using this command line

telnet

open [IP] [PORT]

and understand if the connection is established or not.

Also I wonder what is the effective difference if I simply use a TCP Sampler.

Thanks

Solution

  • Given you have groovy tag here's how you can test the connectivity using Socket class, the example code would be something like:

    def sock = new Socket()
sock.setSoTimeout(1000)
sock.connect(new InetSocketAddress("example.com",80))

if (sock.isConnected()) {
    log.info('Connection established')
}
else {
    log.info('Server is not listening')
}

    JMeter Groovy Telnet

    Also be aware that you can invoke telnet command directly using String.execute() method like:

    "telnet example.com 80".execute().text

    And last but not the least, you can run an arbitrary command or program using JMeter's OS Process Sampler.
