JMeter Logs

OctoPerf lets you view JMeter logs after executing a Virtual User validation or a load test.

To view the 500 first lines of a log file, simply select it on the left table. Its content appears on the right.

You can also download the full log file by clicking on the Download button. A .log.gz is downloaded when you click on it. You need a file compression tool like 7Zip to extract it.

Log files may not be present in several cases:

  • You cancelled a virtual user validation before it ended.
  • The virtual user validation or the load test failed to start.
  • The virtual user validation was executed too long ago, the log files may be erased in such case.
