Good evening,
You can modify the audit.log.service.headerFormat cluster wide property and set the value to: log_type="gateway" api="{3}" request_id="${requestId}"
This will change the default from "2016-10-17T15:46:26.417-0700 INFO 32705 com.l7tech.server.message : Processing request for service: log [/log]"
to
"2016-10-17T15:54:26.419-0700 INFO 32768 com.l7tech.server.message : log_type="gateway" api="log [/log]" request_id="00000157c3fce83c-400""
Sincerely,
Stephen Hughes
Director, CA Support
