Understanding Jmeter Results

Jmeter:Understanding Summary Report

The summary report shows values about the measurementJmeterhas done while calling the same page as if many users are calling the page. It gives the result in tabular format which you can save as .csv file.
These are some main headings in the summary resultlistener. Lets understand them in detail:

Summary Report

In the above image you can see in the red lined box: Label, Samples, Average, Max, Min, Std.Dev, Error%, Throughput, KB/Sec, Avg.Bytes.

Label:In the label section you will able to see all the recorded http request, during test run or after test run.


Samples:Samplesdenoteto the number of http request ran for given thread. Like we have one http request and we run it with 5 users, than the number of samples will be 5x1=5.
Same if the sample ran two times for the single user, than the number of samples for 5 users will be 5x2=10.


Average: Average is the average response time for thatparticularhttp request. This response time is inmillisecond. Like in the image you can see for first label, in which the number of sample is 4 because that sample run 2 time for single user and i ran the test with 2 user. So for 4 samples the averageresponse time is 401 ms.


Min:Min denotes to the minimum responsetimetaken by the http request. Like for the above image the minimum response time for first four samples is 266 ms. It means one http request responded in 266 ms out of four samples.


Max:Maxdenotes to the maximum responsetimetaken by the http request. Like for the above image the maximum response time for first four samples is 552 ms. It means one http request responded in 552 ms out of four samples.


Std.Deviation:This shows how many exceptional cases were found which were deviating from the average value of the receiving time. The lesser this value more consistent the time pattern is assumed.


Error %:This denotes the error percentage in samples during run. This error can be of 404(file not found), or may be exception or any kind of error during test run will be shown in Error %. In the above image the error % is zero, because all the requests ran successfully.


Throughput:Thethroughputis the number of requests per unit of time (seconds, minutes, hours) that are sent to your server during the test.
