I have set up the Load Profile for 5000 Users using ultimate thread group
[Ultimate Thread Group Load ][1][1]: https://i.stack.imgur.com/99C8O.png
If I execute in non-GUI mode, only a single .jtl or CSV file gets generated after the end of the execution. is it possible to generate the .jtl file based on the Thread count mentioned in the ultimate Thread group like 1-30, 31-90, 91-240...? Splitting the .jtl and generate the HTML Report based on the Thread Count?
The easiest would be using Filter Results Tool which can extract parts of the single .jtl basing on start and end time offsets, for example:
FilterResults.bat --output-file 0-30.csv --input-file your-results-file.jtl --start-offset 0 --end-offset 190
will give you first 30 users
FilterResults.bat --output-file 31-90.csv --input-file your-results-file.jtl --start-offset 190 --end-offset 505
Filter Results Tool can be installed using JMeter Plugins Manager

My Requirement is to execute 10 request per second for 5 minutes. The configuration I have used is
Thread Group Properties:
number of threads : 600
ramp up period : 60
Loop count : 5,
Add Sampler -> Flow Control Action
Select Logical Action on thread as Pause
Duration(milliseconds) :60000
I used the below command to run jmx from command line to generate xls and generate html report.
/jmeter.sh -n -t demo.jmx -l demo.xls -e -o ./report
Need to know if the configuration I have mapped is correct or not?
I have also looked at constant throughput timer and Runtime controller to stop the execution after 5 mins?
I am not able to validate the end result?
You can see what actual throughput your test generated using Transactions Per Second listener or the relevant chart in the HTML Reporting Dashboard
With regards to configuring JMeter for sending 10 requests per second for 5 minutes I would rather recommend going for Concurrency Thread Group and Throughput Shaping Timer combination.
Configurations:
Look at the results in Non-GUI Console
Look at the results in GUI Listener
It's very strange, I see different results for the same test.
The Average Response Time on Non-GUI Console displays as: 368 ms, whereas it displays 578 ms on Listener
Likewise, the Maximum Response Time on Non-GUI Console displays as: 4524 ms, whereas it displays 9999 ms on Listener
It appears to be happening on Jmeter 5.1.1 version, can someone help me out.
In the Summariser:
summary = 9377
In the Summary Report:
TOTAL = 11941
My expectation is that the inconsistency is being caused by extra ~2500 sample results in the .jtl results file, to wit you're appending the results of the current test run to the results of the previous test run. JMeter's summariser considers only current session and when you load the .jtl file in the Listener - it calculates the average from all entries in the file.
Consider passing -f command-line argument to your JMeter startup command line like:
jmeter -f -n -t test.jms -l result.jtl
this way you should get "clean" results and Summariser output will be in line with the Listener output
Thanks #Dmitri for pointing out the deviation of Sample size in Summariser and Listener which was causing the other Performance Metrics.
It all worked when I edited the below configuration in the Jmeter.properties file
Thanks
My Test plan has a csv dataset config element, a thread group with a http sampler.
I would like to read first element from csv, run it using 20 threads for 50 iterations, then repeat this sequential process for all the 30 rows of my csv.
I have set the toggle for stop on eof to true.
Most solutions,I have gone through on Stack Overflow, andother blogs, for a suitable solution, suggest adding a loop controller or a while loop, reading the rows using a preprocessor and looping, however, in these cases, I am not able to achieve my objective.
TestPlan
-- User Defined Variables
-- HTTP Request Defaults
-- HTTP Header Manager
-- JSR223 PreProcessor (To get the CSV line count)
-- CSV Data Set Config (Recycle on EOF - False, Stop on EOF - True)
-- Thread Group
-- HTTP Sampler (GET,pass each of the csv dataset element as part of path)
-- View Result Tree
With the above setup, I see that the whole csv is iterated, I inlcuded a loop controller, with loop count, moved the HTTP sampler, under it.
However, when I do this, I was unable to get the usage of Iterations in thread-group.

How to loop each thread with unique data from CSV Data Config file
JMeter - multiple user taking unique row from CSV file
Your requirement is too "exotic", I would recommend creating a new CSV file out of your existing one with:
1st line repeated 100 times (20 threads x 50 iterations)
2nd line repeated 100 times
3rd line repeated 100 times
...
30th line repeated 100 times
If you have problems generating the file you can do this in the runtime, like:
Add setUp Thread Group with 1 thread and 1 loop to your test plan
Add JSR223 Sampler to the Thread Group
Put the following code into "Script" area:
SampleResult.setIgnore()
def generated = new File('/path/to/new/csv/file')
generated.delete()
new File('/path/to/old/csv/file').readLines().each { line ->
1.upto(100, {
generated << line << System.getProperty('line.separator')
})
}
In main Thread Group use CSV Data Set Config "normally", just point it to use the /path/to/new/csv/file

Am running recorded jmeter performance script (by adding summary and aggrgate listners), in non-gui mode using Maven. After running am getting .jtl file, but am not seeing the values for summary and aggregate values.
how can i see the summary or aggregate report in .jtl file, without opening Jmeter GUI.
We are planneing to run through jenkins on daily basis. Once jtl file is generated the other script has to look the values for summary / aggregate values and show it on the dashboard.
Can anybody please help me regarding this.
Typically I set the results file int the Summary Report Listener and select the fields I want to get back. When you run the test via non-gui (ie through Jenkins) you will get the summary results file and it should be in your workspace.
Here is my JMX file, testing some mobile APIs. JMeter Test Plan and Results
Also to note is the Generate Summary Results Listener. Per the docs
In Non-GUI mode by default a Generate Summary Results listener named "summariser" is configured,
This will not show up in the JTL but will show up in your log file and will generate lines such as
2015/08/28 15:14:33.305 INFO - jmeter.reporters.Summariser: summary = 2200 in 169s = 13.0/s Avg: 17 Min: 2 Max: 5129 Err: 0 (0.00%)
The values you're used to see in Aggregate Report / Summary Report listeners are being calculated from the following metrics:
timestamp
elapsed
success
bytes
latency
For instance:
Average metric is sub of "elapsed" times for all the samplers divided by samplers count.
Median metric is a common statistical measurement basically 50% percentile
90%, 95%, 99% - are also percentiles like median
etc.
Depending on your skills set you can check i.e. Calculator.java class code to see how JMeter calculates averages, percentiles, throughput, etc. and implement some form of postprocessor, use MS Excel, LibreOffice Calc or equivalent on .jtl CSV results file.
If you need to get these results after JMeter run the easiest option are:
Vanilla Jmeter:
if you launch JMeter via Ant Task or Maven Plugin - you'll get HTML results file like:
For more information on configuring Ant and/or Maven integration refer above links or Five Ways To Launch a JMeter Test without Using the JMeter GUI guide.
Using JMeter plugins:

1 Threads: 2350/5000 Samples: 142 Latency: 19 Resp.Time: 19 Errors: 0%
2 Threads: 4500/5000 Samples: 130 Latency: 51 Resp.Time: 51 Errors: 0%
3 Threads: 5000/5000 Samples: 153 Latency: 81 Resp.Time: 81 Errors: 0%

How to generte csv file and load csv using response time graph listener?
Can any one help me in detail that how we find response time in jmeter ?
If you run JMeter in command-line non-GUI mode as follows:
jmeter -n -t /path/to/your/test_plan.jmx -l /path/to/results_file.jtl
your results_file.jtl content will look like:
1409124780902,182,Logon,200,OK,Thread Group 1-1,text,true,214,0
1409124781219,153,Logout,200,OK,Thread Group 1-1,text,true,110,0
where second column is page response time in milliseconds.
Other values are:
"1409124780902" - current time stamp in ms
"182" - page response time
"Logon" - sampler name
"200" - Response Code
"OK" - Response Message
"Thread Group 1-1" - Parent Thread Group name, thread number and iteration.
"text" - response data type
"214" - response data size in bytes
"0" - latency
Once your test run is done you can open JMeter GUI and load this results_file.jtl into the listener of your choice.
You might also be interested in JMeter Plugins Extras Set which is capable of generating nice looking and easy understandable response-time related graphs to wit:
Response Times vs Threads
Response Times Distribution
Response Times Percentiles
You can get it by adding Reporters.
Please keep in mind Reporters is cpu and memory intensive components and thus should not be used while actual load test.
But for sample testing you can use it and for load test run you can get response time, average,throughput etc by saving output to jtl file in JMeter.
For normal/sample run
Aggregate report gives Average response time, min, max, median etc.
Summary report also gives the same with less details,
While performing actual run you can save output of these reporters in a jtl file. After the test results can be analyzed from jtl files.
