how to remove these logs. Very hard to see our real logs in among that noise.

I believe it's already fixed here:

I installed Traccar a few weeks ago on a GCP virtual machine using Docker. The version of Traccar we're currently using is 5.12. Could you please let me know which version the issue we're experiencing was fixed in?

Anton Tananaeva year ago

It will be fixed in the next version.
