Test Initialization Logs

OctoPerf lets you review the process of initializing the load injector via a Test Initialization Logs panel:

Docker Logs modal

The test status goes through a number of steps. You can find more details on the test status page.

This log also shows the IPs of the load generators, this can be useful if you want to filter these calls from your statistics or logs.

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.

  • The virtual user validation or the load test failed to start,
