Question
How do I modify the Apache LogFormat?
Answer
The Apache LogFormat can be customized inside the WHM interface "Home »Service Configuration »Apache Configuration »Global Configuration". It is advised that any changes be appended to the default configuration to ensure continued functionality for statistics and bandwidth tracking. All changes must meet the Apache format requirements or the change will be rejected.
See the following documentation for further details.
