I'm executing Jmeter from command line using following command
!JMeter -Jjmeter.save.saveservice.samplerData=true -Jjmeter.save.saveservice.response_data=true -Jjmeter.save.saveservice.output_format=xml -Jjmeter.save.saveservice.responseHeaders=true -Jjmeter.save.saveservice.requestHeaders=true -Jsummariser.out=false -n -t .jmx -l JmeterReports\TestReport.xml -j JmeterReports\jmeter.log
At the end of the run, I get a tidying up message and it takes 50 mins. Any hint on how to avoid this. it impacts my testing time.

First of all consider disabling all these Results File Configuration overrides as storing all requests and responses data into the .jtl file for one hour test causes massive disk IO, moreover writing XML is more resource intensive process than default CSV output
If the problem is still there take a thread dump and inspect what the threads are doing and which are stuck or waiting
Monitor the JVM metrics using JVisualVM or equivalent, it might be the case JVM does excessive garbage collection due to low heap space or something like this

I am new to JMeter so bear with me...
I have a setUp Thread Group where I am grabbing a token and then re-using that in the HTTP Header Manager within the main Thread Group. Within that Thread Group I have the following parameters set...
I run this command to execute the tests:
jmeter -n -t PSC_Token.jmx -l testPsc.jtl -f
When I open the testPsc.jtl file though in Summary Report, I would expect that each request would show 600 for # Samples (200 threads * 3 loop count) but it is showing 1200 for each.
I tried deleting the file entirely and re-running it, just in case it was appending or something strange. That doesn't resolve the issue though.
Any ideas?
You're writing the same data into the same file 2 times, the options are in:
Disable (or better delete) the Summary Report listener, in general Listeners don't add any value, they only consume resources
Or remove -l command line argument and run your test just like:
jmeter -n -t PSC_Token.jmx
Also be aware that according to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.5 (or whatever is the latest stable version available at JMeter Downloads page)
I need to have 2 output files, one with successes only and another one with failed status. First file must be in CSV format and another in XML (it must contain response data with response body). The solution must be in the non gui mode.
My current solution with one file:
jmeter.bat -Jjmeter.save.saveservice.output_format=xml -Jjmeter.save.saveservice.response_data=true -n -t JMeterFile.jmx -l OutputFile.jtl
I don't know how to make two output files with different content.
For the default .jtl file in CSV (for example suitable for generating HTML Reporting Dashboard) format run JMeter in command-line non-GUI mode like:
jmeter.bat -n -t JMeterFile.jmx -l OutputFile.jtl
For getting another file with detailed information on errors add a Listener, i.e. Simple Data Writer would be a good choice and configure it like:
This way you will get 2 files:
OutputFile.jtl - in CSV format with all metrics for all Samplers
Errors.xml - in XML format for failed samplers only having response data (you can tick other boxes as well if you want more details)

I am using Jmeter Version 4. For example I am running test for four hours, And during the test run, I want the result file for the test ran from 2nd to 3rd hour.Is it possible to get the result file like that?
I know that we can get the result file from starting to 3rd hour.But I want from 2nd to 3rd hour.
Can I get that.Please suggest?
The easiest option is going for Filter Results Tool which has --start-offset and --end-offset parameters specifying how to "cut" the original .jtl file (in seconds) so you could do something like:
FilterResults --output-file from2ndto3rd_hour.jtl --input-file /path/to/large/result.jtl --start-offset 7200 --end-offset 10800
Filter Results Tool can be installed using JMeter Plugins Manager:
Ideally, you should use this solution that allows you to have live results:
https://jmeter.apache.org/usermanual/realtime-results.html
But if you want to work with CSV, your best bet would be to modify the timestamp format by adding to user.properties :
jmeter.save.saveservice.timestamp_format=yyyyMMddHHmmss
And ensure JMeter flushes on every write to avoid having partial lines:
jmeter.save.saveservice.autoflush=true
And then use grep, for example to take results between 15 and 16h on 26 january 2019
grep "2019012615" results.csv > filter.csv
If you don't want to rely on grep, then you can take the whole file and generate the HTML report using :
jmeter -Jjmeter.reportgenerator.start_date=20190126150000 -Jjmeter.reportgenerator.end_date=20190126160000 -g results.csv -o reportfolder
I'm getting result in GBs under jtl files, so how I can save jtl files in parts so that I can delete older files during Jmeter run.
jmeter -n -t test.jmx -j D:\jmeter.log -l D:\jmeterJTL.jtl
Above command will save the jmeter.log and jmeterJTL.jtl file in directory (D:). But I'm getting 1 gb data in 1 hour so how I can save this in parts: jmeter1.log jmeter2.log jmeter3.log ... and jmeterJTL1.jt1 jmeterJTL2.jt1 jmeterJTL3.jt1 ...
Note: I'm also saving result in .jtl to logged in thread name so that I can debug. Is there any alternative for this?
You are writing more response data (might be whole response data). You can reduce the file size by configuring the below properties.
In your jmeter.properties or user.properties file, use the following:
jmeter.save.saveservice.output_format=csv
jmeter.save.saveservice.subresults=false
You can check this blazemeter blog to learn more about how to tune the performance of JMeter.
I have an aggregate report:
Do I have to add another listener or add anything else to the testplan?
For ex: consider the above snapshot:
I'm running 9002 samples, I just need to know the total time required for all the 9002 samples?
If your 9002 Samples are played in a sequence by only 1 user, just use a TransactionController that will contain your HTTP Request and you will have this.
If 9002 samples are played by different users then you can export the CSV file that contains the test results and use Excel to sum up the elapsed column.
To generate a CSV file, run test in NON GUI Mode using:
jmeter -n -l results.csv -t test.jmx
