Obviously, I know that I have response time in .jtl file and in listener called Aggregate report, but I'm looking for way to get reponse time of request to variable.
You can do it as follows:
Add Beanshell PostProcessor as a child of the request
Put the following code into PostProcessor's "Script" area:
vars.put("responseTime", String.valueOf(prev.getTime()));
It will get elapsed time for the sampler (in milliseconds) and store it into ${responseTime} variable. You can add sampler label as prefix or postfix to distinguish response times for different samplers.
prev is a shorthand for parent SampleResult instance.
See How to Use BeanShell: JMeter's Favorite Built-in Component for comprehensive information on Beanshell scripting in JMeter tests.

I'm new to Jmeter and vigorously learning.
I wanted to know how JSR223 Sampler and JSR223 PreProcessor are different, can a sampler be used the same way as the preprocessor?
General difference is that PreProcessor won't be executed unless it has a sampler in its scope which it will be triggered (per sampler)
Pre-Processor element is defined to alter the settings of Samplers in their scope. It will always execute before the actual sampler request.
Specific difference is that JSR223 PreProcessor doesn't have SampleResult available, so for example you can't execute the following example:
SampleResult.setStopTest(true);
The SampleResult ResponseData is set from the return value of the script. If the script returns null, it can set the response directly, by using the method SampleResult.setResponseData(data), where data is either a String or a byte array. The data type defaults to "text", but can be set to binary by using the method SampleResult.setDataType(SampleResult.BINARY).
The SampleResult variable gives the script full access to all the fields and methods in the SampleResult. For example, the script has access to the methods setStopThread(boolean) and setStopTest(boolean).
JSR223 Sampler is a Sampler, so it will generate a SampleResult which will appear in the Test Results (unless you call SampleResult.setIgnore() method)
JSR223 PreProcessor cannot be executed per se, you need to connect it to one (or many) Samplers according to JMeter Scoping Rules so it will be executed before one (or many) samplers. PreProcessors execution time is not reflected in the test results (unless you use a Transaction Controller configured to include it)
Both can run an arbitrary code (it's recommended to stick to Groovy) so which one is to use mostly depends on your use case, if you need to conduct the load and measure the time - go for the Sampler, if you need to set up some data - go for the PreProcessor, etc.
I am trying to remove response time and samplers from my Jmeter results in summary report. I know we can do it with help of Filter Result options, but it just removes the label or samplers and it still shows the and adds up its response time. But suppose I have bunch of samplers in a transaction controller and I want to remove or ignore the response time of some of samplers (I can not disable them, I have send them I just don't want to consider their response time) then how should I do it? is there a way?
I don't believe there is an easy way of excluding Transaction Controller's children from the .jtl file.
You can visualize the results using i.e. BM.Sense analysis solution, in Composite Timeline Analysis panel you have the possibility to choose which sampler(s) to display so you can filter out the results you're not interested in
If your goal is to execute the request but not to display it in the results you can add a JSR223 PostProcessor as a child of the request you would like to omit and put the following code into "Script" area:
prev.setIgnore()
This way the sampler(s) in the JSR223 PostProcessor's scope will be excluded from any form of reports:
I cannot seem to save the load/response/sample time into a variable using RegEx.
Sampler Results page
Is there a way to access the results from the Sampler Results page?
You cannot extract Response time using regular expressions because regular expression extractor is limited to the following options and response time is calculated by JMeter
However you can use JMeter's SampleResult api to get load time.
The api has methods for endtime and starttime of a sample, using this methods you can calculate load time and then store it in JMeter variable.
Loadtime= endtime-starttime
Add a Beanshell post processor to your sampler and add the following code to the post processor
long starttime=prev.getStartTime();
long endtime=prev.getEndTime();
int loadtime=endtime-starttime;
vars.put("Load time",Integer.toString(loadtime));
You can use ${Load time} to get load time of that particular sample

Beanshell
My test configuration :
Loop Controller
--> Beanshell Sampler
vars.put("test", "${__CSVRead(*test,0)}");
Add it to an existing array retrieved from vars.getObject
In the above scenario, I am constructing my request payload dynamically in a loop controller. I had to put the CSVRead function in a separate Beanshell sampler under the loop controller since "${__CSVRead(*test,0)}" was reading the sample line if I use it within a for loop inside the beanshell sampler (interpreted mode).
While the above configuration meets my requirement, my *.jtl files are growing in size even for a 30 minute load test since the BeanShell sampler is getting measured all the time. While I am able to filter the required data by using the FilterResults tool, I want to know how to avoid this during the execution itself like the TestActionSampler
Use one of the following Test Elements instead:
BeanShell PreProcessor
BeanShell PostProcessor
Beanshell Timer
By default Timers and Pre/Post Processors execution time is not included into parent sampler elapsed time (unless you use Transaction Controller explicitly configured to do so), using this approach you will be able to exclude the time, required for constructing payload from test results.
I resolved it by using the following configuration.
Loop Controller
--> Test Action Sampler
--> Beanshell timer returning 0 at the end
vars.put("test", "${__CSVRead(*test,0)}");
Add it to an existing array retrieved from vars.getObject
return 0;
My script structure looks like that:
Transaction Controller SEARCHING OFFERS Transaction
http request offers
http request offers details
Beanshell PostProcessor
Which BeanShell command let me to get name, response code, response time, test result and test time for whole transaction?
Where I should attach BeanShell PostProcessor?
Which code I should use, but in my opinion
String name = sampler.getName();
doesn't work correctly for me.
IMO you should be using BeanShell Listener instead of Beanshell PostProcessor. Listener can be at the same place where your current Beanshell PostProcessor is. That object has access to sampleResult, which would contain response code / response time / etc, for example:
sampleResult.getSampleLabel(); // the name, e.g. 'SEARCHING OFFERS Transaction'
Full list of SampleResult functions is here
If you only want to process transactions in this listener, you could filter them (e.g. by name).
