Which part of a syslog log contains a descriptive text about the event in a free text format?

In a syslog log, the part that contains a descriptive text about the event in a free text format is the “message” part. The message part of a syslog entry typically includes detailed information about the event, written in a human-readable format. It can contain various types of data depending on what is being logged and the source of the log. This is the section where the actual content of the log is presented, describing what happened in a format that can be directly interpreted by a person reviewing the log.
