Performance testing using Blaze Meter RTE Plug in for Mico focus Reflection Application.

[Rnandiraju]

Hello,

I have been trying to use the RTE plugin in Jmeter to test the Microfocus Reflection application.

When I try to connect using the recorder it gives the below error.

2022-04-20 08:54:03,292 ERROR o.a.j.JMeter: Uncaught exception in thread Thread[Thread-9,5,main]

Hello @Rnandiraju,

Thanks for taking the time to report this behaviour, we really appreciate it.

Some users have experienced issues with unsupported telnet commands while using our plugin. We found that this particular workaround worked for some of them (but none provided flows for us to try to fix it more accordingly).

In order to help you, could you:

1. Share with me a TestPlan/JTL so we can reproduce your scenario and fix it?
2. Try that proposed workaround and let us know if that works in your case?

The 1st option would also help the community, thus, we could mention you as scenario collaborators The 2nd option would also prove another case where this is the correct approach (and such, we could implement it on our end).

Regardless of the option you pick, please let me know either here or in my email (ricardo.poleo@blazemeter.com) and, as always:

Happy Hacking!

Hello Ricardo Poleo,

The work around suggested did not work.

Any other options?
