Log Field Details

Field Description Level

Field	Description	Level
log.level	Original log level of the log event. Some examples are `warn`, `error`, `i`. type: keyword example: `err`	core
log.logger	The name of the logger inside an application. This is usually the name of the class which initialized the logger, or can be a custom name. type: keyword example: `org.elasticsearch.bootstrap.Bootstrap`	core
log.original	This is the original log message and contains the full log message before splitting it up in multiple parts. In contrast to the `message` field which can contain an extracted part of the log message, this field contains the original, full log message. It can have already some modifications applied like encoding or new lines removed to clean up the log message. This field is not indexed and doc_values are disabled so it can’t be queried but the value can be retrieved from `_source`. type: keyword example: `Sep 19 08:26:10 localhost My log`	core
