This article intends to show you how to enable 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 to "Enable Piped Apache Logs" and click the "Save" button.
Documentation for this feature is available here.
