Chapter 52. Log
Log Component
The log: component logs message exchanges to the underlying logging mechanism.
URI format
log:loggingCategory[?options]
Where loggingCategory is the name of the logging category to use. You can append query options to the
URI in the following format, ?option=value&option=value&...
For example, a log endpoint typically specifies the logging level using the level option, as follows:
log:org.apache.camel.example?level=DEBUG
The default logger logs every exchange (regular logging). But Fuse Mediation Router also ships with the
Throughput logger, which is used whenever the groupSize option is specified.
Also a log in the DSL
In Camel 2.2 onwards there is a log directly in the DSL, but it has a different purpose. Its meant for lightweight
and human logs. See more details at LogEIP.
