Jmeter Listeners : View result Tree and Aggregate Graph

A listener is a component that shows the results of the samples. The results can be shown in a tree, tables, graphs or simply written to a log file. To view the contents of a response from any given sampler, add either of the Listeners "View Results Tree" or "View Results in table" to a test plan. To view the response time graphically, add graph results, spline results or distribution graph.

Listeners provide access to the information JMeter gathers about the test cases while JMeter runs. The results or information gathered by listeners can be shown in the form of:

  a)  tree

  b)  tables

   c) graphs

  d)  log file

All listeners write the same raw data to the output file when one is specified.

Aggregated graph

Gives all the statistics concerning the tests
May be recorded in a specified file for further treatment (data mining)



Result tree

Gives in a tree form, all the samplers results, the requests, and the sampler  data.
May  also be recorded in a specified file for further treatment
