| = Simple Logger |
| |
| Even though Log4j Core is the reference implementation of xref:manual/api.adoc[Log4j API], Log4j API itself also provides a very minimalist implementation: link:../javadoc/log4j-api/org/apache/logging/log4j/simple/SimpleLogger.html[`SimpleLogger`]. |
| This is a convenience for environments where either a fully-fledged logging implementation is missing, or cannot be included for other reasons. |
| `SimpleLogger` is the default Log4j API implementation if no other is available in the classpath. |
| |
| [#config] |
| == Configuration |
| |
| `SimpleLogger` can be configured using the following system properties: |
| |
| include::partial$manual/systemproperties/properties-simple-logger.adoc[leveloffset=+1] |
| |
| === Thread context |
| |
| Simple Logger supports the same properties as Log4j Core for the configuration of the thread context. |
| See xref:manual/systemproperties.adoc#properties-thread-context[] for details. |
