Running a Jetstress Test with JetstressCmd.exe

 

Topic Last Modified: 2007-02-09

Both JetstressWin.exe and JetstressCmd.exe use the common Jetstress core library files so you will have comparable test results with the same XML configuration file. We recommend that you use JetstressWin.exe to create new test scenarios, and JetstressCmd.exe to open and run the test scenarios by using the /config command-line option. You can also see all the other available options by using the /? (help) command-line option.

If you type /? At the command line, you will see the following.

C:\Program Files\Exchange Jetstress>JetstressCmd.exe /?
