Information on Jira Dater Center TRACE Logging

Nathaniel Simpson_rh9f9q

As Part of the ACP-100 Preparation Materials, it mentions that you need to know information surrounding logging . (See Below)

My question is specifically around TRACE logging, I cannot see it defined in any of the predefined logging levels. And no information about it.

What is TRACE logging? How do you activate it? What are the use cases for it i.e. would you use it for an organizational app that is not working properly?

 

(From ACP-100 Prep) Logging and profiling

• set logging for packages

• Levels include Trace, Debug, Info, Warn, Error, Fatal, Off

 

The logging information for the other levels I have been able to find below

• DEBUG - designates fine-grained informational events that are most useful to debug an application (what is going on)

• INFO - announcements about the normal operation of the system - scheduled jobs running, services starting and stopping, user-triggered processes and actions

• WARN - any condition that, while not an error in itself, may indicate that the system is running sub-optimally

• ERROR - a condition that indicates something has gone wrong with the system

• FATAL - a condition that indicates something has gone wrong so badly that the system can not recover

• TRACE - ??????????????????

 

Thank you for your help, to further improve my understanding.

Hi @Nathaniel Simpson 

Basically Atlassian not mentioning this log level in their docs:
https://confluence.atlassian.com/adminjiraserver/logging-and-profiling-938847671.html

However, they do mention that: Jira uses a powerful logging module called log4j for runtime logging.
