Describe what are you trying to do:
Hi. I am trying to export logs, metrics and traces to external services following the example in the playground.
I've tested the audit tool using the configuration sample present in the playground and it returns:

0.602 4.1.3     [HIGH]          Avoid duplicating telemetry options to prevent system overload.

What is the right approach to export logs, metrics and traces to avoid this misconfiguration?

Your configuration file:

krakend.json
