I have updated user.properties to display following percentile values. However the html report generated is not taking 99.9th percentile instead showing up two 99th percentile columns. It can take any int number like 98th or 92nd percentile but not taking a float number.
Is this a bug? or Am I missing something? Appreciate any help on this.
aggregate_rpt_pct1=95
aggregate_rpt_pct2=99
aggregate_rpt_pct3=99.9
I cannot reproduce your issue using latest JMeter 5.4.1
I don't know where did you put these properties overrides, just in case they should go to user.properties file and JMeter restart will be required to apply them.
Another option is passing the custom percentiles via -J command-line argument like:
jmeter -Jaggregate_rpt_pct1=95 -Jaggregate_rpt_pct2=99 -Jaggregate_rpt_pct3=99.9 -n -t test.jmx -f -l result.jtl -e -o dashboard
And last but not the least, it might be the case you're looking into "old" dashboard, try providing -f argument so JMeter would delete existing dashboard folder and generate a brand new one.

i have a jtl report of my 4 hours load test. I would like to take the results of only 2 hours and save it again as a jtl(not csv, as we can achieve in synthesis report) i Tried using sythesis report ,we get the results of particular time frame but not able to save it as jtl.
Please can anyone help me . I would like to take the results of first 2 hours and save it again as a jtl file.
Update:
I have used filterresult jar and used cmd with the mentioned command but as u can see in the screenshot after loading file result is not getting generated in the result folder.
Check out Filter Results Tool plugin, it has --start-offset and --end-offset parameters so you will be able to "cut" your .jtl results file for given timeframe and save it as .jtl without any transformations.
You can install Filter Results Tool using JMeter Plugins Manager
#Shey..Please check the below plugin, It has the GUI and you can filter the results. I hope this is easier than cmd line.
I have a JMeter test that is invoking an API (send API) in an asynchronous manner. The result of the invocation is then available via the other API call (results API). When I consume results, I do have a metrics about several phases of processing in the JSON response, which I would like to push into the resulting JMeter report.
I would like to get averages for that data, not just average times on the overall end-to-end test.
Is it something that can be implemented in JMeter?
Injecting custom fields into .jtl results file can be done using sample_variables property
Given you have 2 JMeter Variables, i.e. foo and bar you can "tell" JMeter to add them to the results file by either adding next line to user.properties file
sample_variables=foo,bar
or passing the values via -J command-line argument like:
jmeter -Jsample_variables=foo,bar -n -t test.jmx -l result.jtl
Once your test finishes you will see 2 extra columns in the .jtl results file holding the values for foo and bar JMeter Variables, hopefully getting average for this data will not be a problem.

This is a job for the Summary Report:
The summary report creates a table row for each differently named request in your test. This is similar to the Aggregate Report , except that it uses less memory
See example:
Average: It is the average time taken by all the samples to execute specific label. In our case, average time for Label 1 is 942 milliseconds & total average time is 584 milliseconds.
I have a jmeter test plan that is composed of a single threadgroup a number of custom java request samplers as children of the thread group and an aggregation listener.
The aggregation listener is writing to a file which includes a row for each invocation of each one of the java samplers. However it is not performing or writing any aggregations.
The default summary however is being produced and written to the log and that contains the aggregated requests/per second etc that I would expect from the aggregation listener.
Can anyone tell me how to either :a) Get the aggregation listener to produce aggregations rather than just a csv file containing rows with the results of each java sampler request? b) Redirect the output of the default test summary to another file?
Don't use listeners as they don't add any value, they just create memory and disk IO overhead. You should be running your JMeter test in command-line non-GUI mode telling JMeter to store the results in a file using -l command-line argument like:
jmeter -n -t test.jmx -l results.jtl
Once your test is done you should be able to open results.jtl file with the listener of your choice and see the results and export them into a file if needed. See Greedy Listeners - Memory Leeches of Performance Testing guide for detailed explanation regarding why you should not be using JMeter Listeners for anything but tests development and/or debugging
If you need to generate the Aggregate Report in unattended manner without interim manual step you will need JMeterPluginsCMD Command Line Tool, using it you will be able to generate different tables and charts from the .jtl results files
For the moment you have only 2 options of storing summariser output: [stdout] (console)5 and jmeter.log file. You can play with JMeter log4j configuration to choose what you want to store there.
To get summarized results add to your test plan Generate Summary Results:
Generates a summary of the test run so far to the log file and/or standard output
Update interval in jmeter.properties to your needs
# interval between summaries (in seconds) default 3 minutes
#summariser.interval=30
I have extracted the data from the response using jmeter's Regular expression extractor.Now i need to print those extracted values in excel.How to do that please help me out.I will be using multiple thread and all those output should be printed in excel as well.
The easiest way it to add the value to JMeter's .jtl results file, just take the next steps:
Add the following line to user.properties file (located in JMeter's "bin" folder)
sample_variables=your_variable_reference_name
or
pass the parameter via -J command-line argument like:
jmeter -Jsample_variables=your_variable_reference_name -n -t test.jmx -l result.jtl
Restart JMeter to pick the change up
Next time you run your JMeter test you will see an extra column in the .jtl results file containing the variable from regular expression extractor value for each sampler

Another approach (for example if CSV format is not suitable for some readon) would be adding Apache POI libraries to JMeter Classpath and using JSR223 Test Elements to create and/or update Excel file, but this approach is harder as you will need to avoid concurrent writes or do in in i.e. tearDown phase to avoid race conditions and data loss.
See Busy Developers' Guide to HSSF and XSSF Features for example code for working with Excel documents using Java/Groovy.
I'm using Jmeter for various performance and load tests and would like to save summary of Summary report and aggregate report automatically when test is done.
Usually summary table when you running form GUI looks like this :
Label | Samples | Average | Min |Max |Error |Throughput |etc.
When I use Write results to file/ Read form file filed , generated report will contain all http requests I generate, it can be millions. File would be huge and even then, no summary on the end . **No average time **
Same situation for aggregate report, I can not auto generate Summary of aggregate reports same as when you use GUI mode. Saved file contain all requests which is not useful at all.
Can I force Jmeter to save those two summaries when test is over ?
thanks in advance
First of all, don't run your test using GUI. Run your JMeter test using command-line non-GUI mode as
jmeter -n -t /path/to/testplan.jmx -l /path/to/results/jtl
Second, disable all the listeners during test run. Once test execution is finished you will be able to open JMeter's GUI, add Listener of your choice to Test Plan or Workbench and use "Browse" button to locate your results.jtl file.
JMeter cannot display only summary as all the "Total" fields are being calculated.
№ Samples - is count of all executed requests
Average - is arithmetical mean of all requests time (sum of all samples elapsed time divided by count)
etc. See JMeter Glossary for metrics explanation
So you got the idea right, it is better to store the necessary minimum, but you need to store something in order to be able to perform results analysis.
You can control what to store by amending properties which names start with jmeter.save.saveservice.. See jmeter.properties file in bin folder of your JMeter installation for the details.
