The .lrr file is stored within the rawresults.zip; however, you can not access the .lrr file directly as they are encrypted by the ALM smart repository. The results can only be reviewed in an HTML format in Jenkins or you can download the rawresults.zip and open in a Standalone Analysis.
In order to view the results in Jenkins after running a performance tests, please do the following:
1. From the Jenkins dashboard, click on the job.
2. Click the Console link to view the PC run information.
3. When the ''Collate and Analyze'' option is set as the post run action, the Performance Center HTML report can be viewed and downloaded directly from Jenkins via the Build Artifacts or Test Result options.
I hope this helps
