Run the command traffic_line -x to apply the configuration changes. Using XML-based custom formats Traffic Server supports a broad range of logging formats, including both standard and traditional custom formats. However, associating these formats to specific servers, collation hosts, and log files is rather coarsegrained. For example, when you enable collation, it is generally enabled for all formats and only to a single collation server. Traffic Server's XML-based custom log specification is more flexible, enabling you to institute much more control over the type of information recorded in your log files. The heart of the XML-based custom logging feature is an XML-based logging configuration file (logs_xml. config) that enables you to create very modular descriptions of logging objects. The logs_xml. config file uses three types of objects to create custom log files: · · · The LogFormat object defines the content of the log file using printf-style format strings. The LogFilter object defines a filter so that you include or exclude certain information from the log file. The LogObject object specifies all the information needed to produce a log file. For example: o The name of the log file (required). [. . . ] A protocol that enables encrypted, authenticated communications across the Internet.
