Alternatives for Real-Time Analysis in Version 3.12.0+

Gatling version: 3.12.0+
Gatling flavor: java kotlin scala javascript typescript
Gatling build tool: maven gradle sbt bundle npm

Hi everyone,

I am working for a performance testing company, and we have onboarded many companies on the open source or enterprise version of Gatling.

Since version 3.12.0, there have been two changes, which we now are struggling with:

  • Graphite has been removed, therefore data cannot be stored in a database anymore for near real-time analysis.
  • The simulation.log file format seems to have changed from plain text to some binary format.

Currently we don’t know any source where we can check what is actually happening while executing a load test, therefore we are basically blind what is going on during an 8 hour test until it is finished, except for OK/KO/User counts from the console log.
Another issue is in case of a test crashing, all the data of the test is basically lost, as no HTML report is created.

I have quite some concerns regarding these changes, as it makes us kinda stuck with gatling version 3.11.
Some of our people already started to think about alternatives to gatling for new projects, as we cannot easily start a new project with it because of these changes.

Does anyone now:

  • Is there a new way how to check execution statistics while a test is still running?
  • Might there be a way to change the output format of simulation.log?
  • Is there a plugin or something that brings back the graphite feature?

Thanks and Regards
