What is the use of debug post-processor in JMeter?
JMeter Debug PostProcessor is used to find the bug in the parent sampler. The output of debug post-processor can be viewed in the ‘View Result Tree’. Basically, Debug PostProcessor displayed 4 properties which are described below in the post.
What is post-processor in JMeter?
Processors are of two types Pre-processor and Post-processor. Pre Processor executes before the sampler execution. Post Processors are used to execute the response data from the server and to save the specific extracted values for later use.
How do I debug JMeter?
JMeter comes with a very useful Debug Sampler which can be used to troubleshoot your script variables. The sampler spits out all variable names and values including arrays; from a regular expression extractor for example. You can add the Debug Sampler by right clicking the thread group, Add, Sampler, Debug Sampler.

- Click “Run” -> “Debug configurations”.
- Select “Remote Java Application”
- Click right mouse button and select “New”
- Insert host ip address and remote port number.
- Click “Apply”
- Click “Debug”
What is the PreProcessor and post-processor in JMeter?
PreProcessor and PostProcessor in JMeter A processor is used to modify the Samplers in its scope. There are two types of processors : Pre-processor : Pre-processor executes some action before making a Sampler Request. Post-processor: Post-processor executes some action after making a Sampler Request.

How do I debug a JMX file?
you can get the step-by-step debugger with just 4 easy steps:
- Open JMeter and go to the Options->Plugin Manager.
- Switch to “Available Plugins” tab.
- Select the “BlazeMeter Step-by-Step Debugger”
- Click “Apply Changes and Restart JMeter”
What is the use of debug sampler?
The Debug sampler is used to debug the script, especially to ensure all the JMeter variables has got the right data in them. This is added during the debug phase of the script and should be deleted / disabled while executing the performance test.
What is result tree in JMeter?
View Result Tree is the one that should be used to debug any request. It allows you to debug Jsonpath, XML or a Regular expression by its user interface. It can be added to your JMeter script through right-click menu: Add > Listener > View Results Tree.
What is pre-processor and post-processor in JMeter?
What is the difference between PreProcessor processor and post-processor?
Both pre-processing and post-processing scripts run before an item or entry is saved. The difference between them is that pre-processing scripts runs before the value and validation rules checking is complete, and post-processing scripts run after these processes.
What is the difference between PreProcessor processor and post processor?
What is JSR223 sampler in JMeter?
JSR223 scripting languages allow you to quickly hack up a process, control flow or other things you would want to do as part of your scripting process. JMeter exposes control flow into your script through Controllers and actual task is carried out by Samplers.
What is the difference between PreProcessor and PostProcessor in JMeter?
PreProcessor and PostProcessor in JMeter Pre-processor : Pre-processor executes some action before making a Sampler Request. Post-processor: Post-processor executes some action after making a Sampler Request.
What is PreProcessor in JMeter?
PreProcessors are actions that are performed before your actual sampler runs in JMeter. It could be something like storing values of a variable, defining timeouts, etc. The preprocessor can be added at the thread group level or sampler level. SampleTimeOut PreProcessor can define the sample time out for a request.
