I'd like to emit access logs in JSON format so as to be able to improve their visibility in our OpenSearch index. In addition to this I made a number of changes:
controller-genExample pod logs showing admin logs and cluster access logs (admin logs left as default - but we can move these to JSON to if we want):
JSON access log (prettified):
{ "response_code": 0, "upstream_cluster": "example-www_TCP_443", "bytes_received": 1294, "bytes_sent": 5999, "downstream_local_address": "10.129.191.27:443", "duration": 445, "upstream_host": "93.184.215.14:443", "downstream_remote_address": "10.129.187.50:48990", "response_flags": "-", "start_time": "2025-01-08T14:12:19.041Z", "upstream_local_address": "10.129.191.27:37028" }
