I am using JMeter in Non-GUI environment.
I am increasing load now, e.g. 1...5000, but I want to decrease load gradually, e.g. 5000...1
Is it possible?
I can't use GUI env.
The easiest way is going for Custom Thread Groups plugins, for example:
Ultimate Thread Group
Stepping Thread Group
You can install these Thread Groups as a part of Custom Thread Groups bundle using JMeter Plugins Manager
Alternatively you can also use Timers to introduce ramp-down logic, however it will be mostly dependent on your application response time

The requirement is to start with 500 users initially and then increase slowly till 10 thousand.
I am new to performance testing, it would be great if anyone could guide me with the steps.
The easiest option is to go for Stepping Thread Group where you can specify how many threads to start initially and how to increase the load gradually.
Example setup
Stepping Thread Group can be installed using Custom Thread Groups bundle using JMeter Plugins Manager
We're getting negative thread count in JMeter for active threads.
The test plan contains various Http Web Test Plan related components and samplers using Parallel Controller. This is creating problems for us in getting correct metrics as JMeter is emitting the same -ve values to the listeners for active threads. Any insights what might be wrong and how to fix this?
Here's the screenshot from the test plan while executing -
First of all don't run JMeter in GUI mode, it's only for tests development and/or debugging, when it comes to test execution you should run JMeter in command-line non-GUI mode
I don't think you should have Parallel Controller as the first parent sampler, the most obvious use case is simulating AJAX requests, concurrency should be set on Thread Group level
I am trying to perform load testing for my Web Application. Have created a Test plan with 16 scenarios using a single thread group. I have added multiple sampler requests under each scenario and used throughput controllers for each of these.
But when the test is run, I noticed that the scenarios are running sequentially whereas i Want the scenarios to run in parallel.
Can someone help me with this please.
This is how JMeter works. Each thread (virtual user) starts executing Samplers upside down (or according to Logic Controllers)
When you add more threads (virtual users) there will be some concurrency, as it evidenced by __threadNum() and __time() functions output:
So just provide enough threads (virtual users) and loops (iterations) on Thread Group level and you will get the concurrency you're looking for
I want to repeatedly simulate load that gradually increases, reaches a peak and then gradually decreases. For example, I want to start with 10 HTTP requests for 1 minute, then 20....until 100 (assume this is the peak). Then when it reaches 100, I want the load gradually to fall, to 90,80,70 until it reaches 10. What is the recommended way to achieve this?
I believe the fastest and the easiest way of achieving this is using custom Thread Groups provided via JMeter Plugins project, i.e. Ultimate Thread Group
The fastest and the easiest way of installing these Thread Groups and keeping them up-to-date is using JMeter Plugins Manager, after installing the Plugins Manager
Go to Options -> Plugins Manager from JMeter's main menu
Switch to Available Plugins tab
Locate Custom Thread Groups and tick the relevant box
Click Apply Changes and Restart JMeter button
I am new to Jmeter and trying to understand what all can be achieved using Jmeter. I want to perform endurance or soak testing of a application using Jmeter, i.e. I want to run a particular script for a particluar number of users for a period of 3 hours.
What all options are available to me and what is the best availablelistener to monitor the result?
Please help. Kindly add if I am missing anything that I should know before starting with soak testing?
For setting up the numbers of users and runtime of the test you use a Thread Group. Setting the runtime is done by checking the Scheduler check-box and specifying Duration.
Of the original listeners in JMeter I have found myself most oftenly just using the plain Summary Report. But JMeter Plugins gives additional listeners which may be better, it depends on what you want to measure. The JMeter Plugins also gives additional thread groups, where you can specify e.g. an increasing load over time.
Use a Thread Group to set up your number of users and the duration of your test (using the scheduler of the Thread Group).
Then add all the samplers and logic controllers you need to perform your testing.
Next, add a Summary Report listener to get an overview of your results (min/max/average and such), and add a View Result Tree listener to get an overview of EACH step your testplan is taking. This Tree listener is great to actually see what jmeter is doing, and to debug your tesplan.
BTW: if you add a HTTP Request Defaults object, you can set your URL and options in there, and don't need to add it to each and every sampler again. Especially works like a charm if you start using regexp extractors and such.
