APACHE customized Logformat : %D

[redleu]

Hi everyone,

we are currently troubleshooting our platform, trying to find out the root cause of a huge TTFB delay on some random HTTP GET operations.
For this, and also to improve our monitoring solution later on, i'd like to customize the Apache logformat and add %D to the list of info to retrieve.
This will display the " The time taken to serve the request".

I'd like to know if anyone already put that in prod and if there are any tricks to know or to take care of?

Hey there! The best way to modify Apache on a cPanel server to adjust the log files would be to edit the template using the details here:

Custom Templates | cPanel & WHM Documentation

A custom template file modifies how cPanel & WHM builds the Apache configuration's virtualhost entries.

docs.cpanel.net

I personally haven't tried using that value to look for TTFB issues, but it's certainly possible other users here have, so they may reply with their thoughts if they see this thread.
