This plugin allows you to track a Gatling simulation in your Jenkins job :
The Gatling simulation's results are stored in the ${GATLING_HOME}/results/ directory. For each simulation's run a folder is created according to the following pattern : mysimulation-20120911161003, the first part is usually the name of the simulation and the second part a timestamp. Therefore fill the field "Output directory prefix" with the first part of this directory name.
