Log.INFO vs. Log.DEBUG [closed]

I am developing a large commercial program and keep confusing myself between what kind of information i want to log with Log.INFO and Log.DEBUG.

Are there any standards or canonical Python Enhancement Proposal / Java standard conventions / rules defined for other languages on what each type of log message contains?

I usually try to use it like this:

• DEBUG: Information interesting for Developers, when trying to debug a problem.
• INFO: Information interesting for Support staff trying to figure out the context of a given error
• WARN to FATAL: Problems and Errors depending on level of damage.

• Debug: fine-grained statements concerning program state, typically used for debugging;

• Info: informational statements concerning program state, representing program events or behavior tracking;

• Warn: statements that describe potentially harmful events or states in the program;

• Error: statements that describe non-fatal errors in the application; this level is used quite often for logging handled exceptions;

• Fatal: statements representing the most severe of error conditions, assumedly resulting in program termination.
