[mrxaxen]

Required for all PRs

• Updated associated README.md.
• Wrote appropriate unit tests.
• Pull request title or commits are in conventional commit format

Just came across the same problem, hoping it'll save a couple of minutes for others in the future.
resolves #10965

Looks good to me. Thanks for fixing this @mrxaxen! Much appreciated!

One more thing to fix...

Hey @mrxaxen thanks for fixing this issue. Can you please change the erroneous sections also in the sample*.conf and then run make docs!?

The background is that the sample*.conf files are embedded into the README.md which would override your changes...

Hey @srebhan! Changed the configuration files (found 2, hoping that's all). Not sure about the CI runs, since's one's reporting on the first commit's message which was accepted last time, and one's reporting on statsd which i have not laid my hands on. Anyways, this is my very first PR here, i'm not really familiar with conventional commits either so pointers are appriciated.

Looks good to me. Thanks @mrxaxen for the fix!
