In support cases, we very often have to request customers to expound on the access log pattern, adding important fields like %T %P and %{tid} Pfor helpful information in reviewing any performance concern or just enough details to accurately correlate specific requests to other specific log messages or correlating dumps.

This means we regularly have to request it and customers have to do restarts and wait for recurrences, causing a lot of repeated support updates and delays in case resolutions. Could we improve our default access log pattern to include additional fields like below that customers most often have to enable for support diagnostics:

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" PID: %P %{tid}P %T" combined
LogFormat "%h %l %u %t \"%r\" %>s %b PID: %P %{tid}P %T" common
