Issue tracker

JMeter uses Bugzilla for issue tracking, i.e. for reporting bugs and requesting enhancements.

Before creating a new issue, please check whether the issue has already been reported by searching Bugzilla. It's also worth checking first on the JMeter user mailing list; others may already have a solution.

Support Questions

Please do not use Bugzilla for asking questions. It is not a support forum. Instead, please subscribe to the JMeter user mailing list and ask there. The user mailing list has a bigger audience and you are more likely to get an answer quickly.

Known Bugs and enhancements

Requesting an enhancement

In most cases it is worth starting a discussion on the mailing list first. Bugzilla is good for tracking progress and supplying patches, but is unwieldy for longer discussions.

If you have not already done so, you need to register an account first, using the "New Account" link at the top of the main Bugzilla page: https://bz.apache.org/bugzilla/.

Make sure you read and understand the information on the account creation page before signing up.

Once logged in, click "File a bug" and select JMeter from the list Please set the severity to "enhancement".

Please make sure that you describe the enhancement in sufficient detail. If necessary provide an example use-case.

If you are providing a code patch, also provide a test case, and documentation on how to use the new feature (ideally as a documentation patch).
