In the context of Java's logging framework, decorations are metadata about the log message. Here is an alphabetic list of decorations that are available:

• level: The level associated with the logged message
• pid: PID = Processor Identifier
• tags: The tag set associated with the logged message
• tid: TID = Thread Identifier
• time: Refers to the current date and time, using the ISO-8601 format
• timemillis: Current time in milliseconds
• timenanos: Current time in nanoseconds
• uptime: Time, in seconds and milliseconds, since the JVM started
• uptimemillis: Time, in milliseconds, since the JVM started
• uptimenanos: Time, in nanoseconds, since the JVM started

Decorations can be surpassed or included in unified logging output. Regardless of which decorations are used, they will appear in the output in the following order:

1. time
2. uptime
3. timemillis
4. uptimemillis
5. timenanos
6. uptimenanos
7. pid
8. tid
9. level
10. tags
