 As a result, you will get `jmeter.log` and `jmeter-results.jtl`. The`jmeter.log` contains information about the test run and can be helpful in determining the cause of an error.  The JTL file is a text file containing the results of a test run. It can be opened in the GUI mode to perform analysis of the results (see the *Output* section below).
