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'm looking for a way to display pie chart/table after running 100 tests, but all available built-in reports seem to accumulate data on time spent per sample, controller and about performance metrics.
Although tests mostly check performance and some metrics are usefull, we also need statistics on actual response data.
Each http request queries service for items availability per product.
After tests finish we also would like pie chart appear with 3 sections:
Available
Low on stock
Unavailable
Now, I found "Save Responses to a file" listener but it generates separate files which isn't very good. Also with "View Results Tree" we can specify filename where responses will be dumped.
We don't need the whole response object and preferably not even write anything to disk.
And than, how to actually visualize that data in JMeter after tests complete? Would it be Aggregate Graph?
So to recap: while threads run, each value from json response object (parsed with JPath) should be remembered somewhere and after tests complete these variables should be grouped and displayed as a pie chart.
I can think only of Sample Variables property, if you add the next line to user.properties file:
sample_variables=value1,value2,etc.
next time when you run JMeter test in command-line non-GUI mode the .jtl result file will contain as many extra columns as you have Sample Variables and each cell will contain respective value of the variable for each Sampler.
You will be able to use Excel or equivalent to build your charts. Alternatively you could use Backend Listener and come up with a Grafana dashboard showing what you need.
I was wondering if there was a easier way to do this. Below is a simple load test specification:
WHen I run for high loads the Summary Report might report percentage errors. And you can also probably view those requests in that View Results Tree page. (That is if we catch the error-ed request quickly enough).
Now what do we do if we want to study all the errors to see if there is some pattern in them, or, simply to know all kinds of errors in the http load test? I am looking for some feature or hack to this effect.
You can generate HTML Reporting Dashboard which provides:
A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles, basically the same as your Summary Report listener
An error table providing a summary of all errors and their proportion in the total requests
A Top 5 Errors by Sampler table providing for every Sampler (excluding Transaction Controller by default) the top 5 Errors
Response codes per second zoomable chart
There is a separate Listener - Response Codes per Second
JMeter .jtl result files are basically .CSV files so you can open it with MS Excel or equivalent and perform grouping or plot errors messages at a timeline chart
And last but not the least, for "high loads" it's recommended to disable or even remove all the Listeners (especially View Results Tree guy) because they don't add any value and just consume the valuable resources.
In the jmeter dashboard I can see three percentile values and I know I can change them by setting the three properties below in the user.properties file.
aggregate_rpt_pct1=50
aggregate_rpt_pct2=60
aggregate_rpt_pct3=70
However, I need these too:
aggregate_rpt_pct1=80
aggregate_rpt_pct2=90
aggregate_rpt_pct3=95
aggregate_rpt_pct3=99
But when I add all of them it only shows three of them. It totally ignores the rest. Is there a way to increase the number of percentiles the dashboard shows? Thanks.
JMeter support only 3 percentiles in dashboard.

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.)
I have build a jMeter test for a mobile web application. The test works perfect and i would see how much data a request cost for the mobile data bundle of the user. Is it possible ?
For downloaded data there are 2 ways to achieve this:
Approximation of downloaded data: Summary Report has
Avg. Bytes - average size of the sample response in bytes.
You could use its value to approximate how much data is downloaded by summing up # Samples x Avg. Bytes over all requests.
If you want more precision, and estimation of both uploaded and downloaded data, you can use one of the programmable listeners (BeanShell listener, BSF Listener or JSR223 Listener) and collect this stats by yourself: they all have access to SampleResult, which allows you to collect the size of the uploaded data (sampleResult.getSamplerData().length()) and the size of the downloaded data (sampleResult.getHeadersSize() + sampleResult.getBodySize()). You can then write this data into file (this is an example for BeanShell)
Add next 2 lines to user.properties file (it is located under /bin folder of your JMeter installation)
jmeter.save.saveservice.print_field_names=false
jmeter.save.saveservice.bytes=true
It will "tell" JMeter to store response size and also adds a header to generated .jtl file when you run your test in command-line non-GUI mode so you could figure out which columns stands for which metric.
You'll need to restart JMeter to pick the properties up.
You'll get something like:
So you will be able to use Excel or equivalent to sum all the "bytes" lines up and calculate the associated cost.
See Apache JMeter Properties Customization Guide for more information on what else can be controller with JMeter properties and what needs to be done to apply the changes.
