I've run a test in Jmeter with some listeners at the Thread Group node. While some of then show information others doesn't.
Does somebody know why the next listeners show no data, please?
Generate summary results
Simle data writer
Response time graph
Save response to a file (doesn't allow saving anything anywhere)

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.
I am new to JMeter. I have taken up HP webtour(127.0.0.1/WebTours) for practicing.
I recorded a scenario for flight booking. I correlated the session ids and found the script was working fine( i was able to see correct HTML pages in View Result Tree).
So, ideally if i run the script a flight should be booked and when i check the application manually i should see a flight but this isn't happening. I run the script,it goes fine but i dont see a flight booked. I have tried to correlate dynamic values and don't see any pending value which isn't been handled.
Any idea on this.
Make sure that you double check the post request were the flight is booked. Because JMeter will put a green if it gets a response with status 200, but it is our responsibly to make sure that we have got the appropriate page. 'Response Assertion' can help you in doing it.
In my test plan I want to make java request and check how it was done by making jdbc request, But I don't exactly know when java request will change DB. I want to make several requests with waiting after each. And if JDBC request doesn't special changes after certain time stop whole test. After that I want to see progress where test plan stopped in view results tree.
BUT
If I use any stop-thread functions, there are no data in View Results Tree.
Haw can I do what I want with jmeter?
Thanks.
you can use a similar mechanism to the one described here:

I have written a load test for a web application. The test script submits a request to the server via HTTP and then polls the server in a While loop with a small timer, to see when the request has been processed. The problem I am having is that in all the listeners (aggregate graph, table, etc.) JMeter only shows the time each request took and not the total time to process the job, i.e. time from initial request sent until response that contains the expected "complete" message.
How can I add something like "profiling points" which will get data onto the listeners graphs? Or is there another way this is typically handled?
You need a Transaction Controller. Put elements times of which you want to aggregate under it. Transaction controller will then appear in all your listeners. Its load and latency times will be sums of those parameters of its nested elements.
Note that this time by default includes all processing within the controller scope, not just the samples, this can be changed by unchecking "Include duration of timer and pre-post processors in generated sample".
