This article intends to show you how to enable or disable piped logging in Apache. Piped logging is beneficial for servers with many domains, as it reduces the number of open files Apache requires.
Log in to WHM as the root user and navigate to the following menu:
Home »Service Configuration »Apache Configuration »Piped Log Configuration
Tick the option "Enable Piped Apache Logs" to enable the service, untick it to disable, and click the "Save" button.
Documentation for this feature is available here.
