Creates log messages using the Simple language

The Log pattern uses a simple language expression to write messages to the log. Messages are logged at INFO level.

The Log pattern can be placed anywhere in the body of a route.

Table 32, “Log Properties” describes the properties you can specify using the properties editor.

Table 32. Log Properties

Name	Description
`Message`	Specifies a Simple language expression that defines the log message.
`Description`	Specifies a text description for the node. This description is included in the generated XML file, but it is informational only. It is not used by Apache Camel.
`Id`	Specifies a unique identifier for the endpoint. The tooling automatically generates an id for a node when it is created, but you can remove that id or replace it with your own. The Camel debugger requires all nodes with a breakpoint set to have a unique id. You can use the id to refer to endpoints in your Camel XML file.
`Log Name`	Specifies the name of the log into which messages are written.
`Logger Ref`	[Camel 2.13.1/2.14.4] Specifies the reference to the particular logger instance to use inside OSGi (JBoss Fuse/Karaf). [QUESTION: Is the reference the name of the logger instance or does it require ? logger=#myLogger URI syntax?] This option requires that a single instance of `slf4j.Logger` be installed in the Registry. For details, see http://camel.apache.org/log.html.
`Logging Level`	Specifies the logging level at which the message is recorded. DEBUG ERROR INFO TRACE WARN OFF
`Marker`	Specifies the name of an optional marker used to enrich logging messages. Conforming SLF4J logging implementations determine how the information conveyed by markers is used.
