(shortdesc] (topicmeta] (topicref][/map/topicref/topicref/topicref {"- map/topicref "}) [/map/topicref/topicref/topicref/topicmeta {"- map/topicmeta "}) [/map/topicref/topicref/topicref/topicmeta/navtitle {"- topic/navtitle "}) Customizing the HTTP access log (navtitle][/map/topicref/topicref/topicref/topicmeta/linktext {"- map/linktext "}) Customizing the HTTP access log (linktext][/map/topicref/topicref/topicref/topicmeta/shortdesc {"- map/shortdesc "}) You can customize the format of the default HTTP access log.

This lets you obtain detailed information about Dgraph processing, to help diagnose unexpected application behavior or performance problems, without stopping and restarting the Dgraph or requiring a configuration update.
