Stepping Thread Group is not working properly in Taurus

[surendra matta]

Hi Andrey ,

When i am running my test with Stepping Thread group in distributed mode  , i am unable to collect the metric from my slave machines.

I have 6 slaves and i scheduled the test with 10 user per slave  but in the blazemeter report i seeing only single slave metrics but in the web-server i am able to see all the 60 users sessions

FYI.. if run this test in Jmeter its working properly without any issues.

When i run the same test in thread group i am able see the all the users metrics in blazemeter .Please find the below snapshot

Let me know if i need to modify any settings.

Regards,

Venkat

 Please find my webserver snapshot at the time of Stepping Thread group test.

Hi,

Please add machineName function to the names of your thread groups as suggested here: http://jmeter-plugins.org/wiki/ActiveThreadsOverTime/

Then try running your test again.

HI Andrey,

Is there any way to declare ramp down in taurus 

FYI.. i am using ramp-down in the execution but it not workins

execution: 

 concurrency: 10

 ramp-up: 120s

 step: 12

 hold-for: 5m

 think-time: 1s

 ramp-down: 20

Please let me know if we have any options .

Regards,

venkat

There's no ramp-down in Taurus. And I'm curious why would anybody need it...

Why do you need the ramp-down?

The main reason is after the test execution in jmeter, it will stop all the threads irrespective of the thread task, it will kill the threads because we completed the duration. For this reason I am seeing sessions alive on my web server because jmeter is not doing proper session logout.

For that reason i am looking rampdown option.

FYI.. In Loadrunner we have the option called --> Ramp-down - Simultaneously .Like that if we have any option please let me know

This is how Stepping Thread Group works in JMeter, it's not Taurus-related behavior.

I'd like to write load test in YAML. But I have found out that it haven't support stepping load profile. Will this feature be implemented in the future versions of Taurus?

Hi,

How did you find that? There is "steps" option which intends to provide stepping patterns.

I'm writting load tests to jmeter, but it is necessary not to use GUI interface to write tests.

I have decided that it is possible to understand writing of scenarios in yaml by their comparison with scenarios of jmeter. I apply jmx2yaml to the scenario for this purpose.

Two thread groups which I usually use are:

1) kg.apc.jmeter.threads.SteppingThreadGroup

2) com.blazemeter.jmeter.threads.arrivals.ArrivalsThreadGroup

When I'm trying to make their converting in yaml, the script always write to console such logs:

10:50:42 INFO: Loading jmx file scripts/test.jmx

10:50:42 INFO: Removing disabled element DebugPostProcessor (Debug PostProcessor)

10:50:42 INFO: Removing disabled element kg.apc.jmeter.samplers.DummySampler (Fake Sampler For Logging)

10:50:42 INFO: Removing disabled element ResultCollector (View Results Tree)

10:50:42 ERROR: Error while processing jmx file: /home/vp.kirnos/test_project/scripts/test.jmx

10:50:42 ERROR: Exception: No thread groups found!

And there is no stepping thread group.

Can you write some Tutorial for Dummy's, how to use Taurus with such thread groups?

Arrivals Thread Group is not supported at the moment, sorry.

Stepping Thread Group is enabled easily, by adding "steps" option into your execution block. Like this:

---

execution:

- scenario: abc
  concurrency: 50
  ramp-up: 1m
  steps: 5

It will be the best solution not only for me, if you add this to 

https://github.com/Blazemeter/taurus/tree/master/examples/jmeter

Thank you very much!
