After running a JMeter load test from command line(nonGUI mode), I would like to have a summary report with each transaction, Avg response times, #of transactions and so on. I tried to achieve it by importing summary_report.jtl file by following the steps.
Open JMeter-UI
Add Summary Report Listener
Browse the summary_report.jtl file that is created during the test.
Now I am seeing all the transactions, #samples, Error% and so on. But average, min, max and std deviation values are ZERO.
What could be the issue here?
Can you see the raw file and check if the latency has been captured properly? If your JTL didn't capture latency you may see all the metrics as 0.
Also check if there is any exception in jmeter.log file when you try to open the jtl. Might help with debugging.
(Also, you mentioned summary_report.jtl, check if your JTL has all the samples or it's a summary report itself.)

after running my performance script , the statistic report generated is quite confusing.
Response Time :6s minimum
90th pct:4.53s
95th pct:4.9s
How come minimum response time is greater then 90th and 95th percentile , am I doing something wrong here ?
It should not be the case, the relevant code lives under StatCalculator.java class
If you do believe that this is a JMeter bug - you should raise an issue in JMeter Bugzilla
The first thing they will ask you is your .jtl results file so if it doesn't contain top-secret information you can update your question with the .jtl file contents so we would be able to look into the issue as well.
P.S. Any chance you're using a Transaction Controller with non-default naming policy? If yes, it might have an impact on results
P.P.S. Any change you're using JMeter Plugins or amending sample results on the fly via Groovy scripting? If yes, it also may influence the test metrics
I have done the below set up in user.properties. I have Jtl files which is of format the csv.
jmeter.save.saveservice.output_format=csv
I am loading the JTL files and getting graph report. which has Average, Median, 95% and 90% Line, Min and Max.
X- Axis --> calls that is made and
Y-Axis --> milliseconds..
I want more info that how many users active and how many error %.
No. of Active Users, Response time, Error %, Transaction per second can we get the details in the graph
Thanks
You can use HTML dashboard generator in your scenario. Have a look at the link and check if it suffice your requirement. Then, follow the procedure to generate it.
You can use it in 2 ways:-
Generation from an existing sample CSV log file
Generation after load test
Both are mention in the jmeter dashboard link provided.
I just want to get the aggregate report include a column for latency.
I have already tried uncommenting jmeter.save.saveservice.latency=true in bin/jmeter.properties.
I am currently using JMeter 3.3
Any help would be greatly appreciated. Thanks!
UPDATE:
A little hack I tried that kind of worked was adding a JSR223 PostProcessor with the following 3 lines of code:
long startTime = prev.getStartTime();
long latency = prev.getLatency();
prev.setEndTime(startTime + latency);
I say kind of worked because it is a hack and even though it was able to correctly reset the average column from load time to latency, it started throwing off the throughput values.
The end goal in my case is just to get the latency along with the other values by running the CMDRunner.jar on the JTL file to output the summary results CSV file.
You can't .
Alternatively why not use the Web Report that exists since 3.0 and that provides a lot of rich information much better than all existing listeners.
See:
https://jmeter.apache.org/usermanual/generating-dashboard.html
When I run the test in GUI, i see the Average, Min, Max in GUI. But when I run in console, is there a way to add these to the csv file?
These values are being calculated so you will be able to see the values only when you open .jtl results file after test finishes in the listener of your choice, i.e. Aggregate Report or Summary Report.
If you want to see the interim statistics while your test is being executed you have the following choices:
JMeter Summarizer output. JMeter reports some numbers into stdout while your test is being running
You can get some extended information if you run your JMeter test using Taurus tool as a wrapper
Both console and web interface options are available, in order to see current test execution stats in browser start your test like:
bzt yourtest.jmx -report
And finally you can use Backend Listener to send your results into database, message queue or web service and use custom plotting application to print out either raw or parsed statistics, here you are limited only by your fantasy:
More information:
JMeter: Real Time Results
How to Use Grafana to Monitor JMeter Non-GUI Results
JMeter produces some basic fields/result_field. JMeter doesn't create everything you see in different types of Listeners.
You can give this a try.
Create a plan
Generate atleast 100 samples (As large amount of data is required for some listeners), using a single sampler (request)
Use as many Listeners as you want of different types (say 15 types of listeners)
Run the plan....
Now in the filename field of all the listeners give series of names of files like a1.jtl a2.jtl
and so on....
see the screen shot
enter image description here
Now again run the plan. Go to the files and open them in some good editors like notepad++.
For your surprise you will find the same data in all the files irrespective of the type of listener generating the file.
Crux of the matter is : JMeter gathers only handful of information from the run, the rest information which is shown in different Listeners is COMPUTED by the JMeter.
So you can read the *.jtl file into any of the listener.
In JMeter, the new way since 3.0 to have results is to use the Web report generated at end of test:
http://jmeter.apache.org/usermanual/generating-dashboard.html
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.
