Hi Patrick,
If I understood correctly, you want to find out which Krakend endpoints are returning a 405. The access log informs about the endpoint path that is being called:
[GIN] 2025/01/16 - 10:05:39 | 405 | 2.427µs | ::1 | GET "/post-endpoint"
This is the default behavior, so I'm missing something here. What are you expecting to see in the logs in order to properly followup the requests?
