Types of messages per logging level

[jawesterholm]

Is there a description of the types of messages included in each of the logging levels (0-7)?

Specifically, I'd like to know the difference between 4,5,6 (info, notifications, warnings)

Thanks.

here is the good document,

https://www.cisco.com/c/en/us/td/docs/routers/access/wireless/software/guide/SysMsgLogging.html

From  my notes as below :

 Logging Messages

Parameter	Level	Syslog Description	Description
emergencies	0	LOG_EMERG	The system is unusable.
alerts	1	LOG_ALERT	Immediate action is required on your part.
critical	2	LOG_CRIT	A critical condition exists on the router.
errors	3	LOG_ERR	An error condition exists on the router.
warnings	4	LOG_WARNING	A warning condition exists on the router.
notifications	5	LOG_NOTICE	A normal but significant event occurred on the router.
informational	6	LOG_INFO	An informational event occurred on the router.
debugging	7	LOG_DEBUG	This is output from debug commands.

Thank you.  

I was hoping for more specific information.

What types of messages are 'Informational'

What types of messages are 'Notifications'

What types of messages are 'Warnings'.

Is there a list or RFC which identifies what messages qualify as information v notification v warning, etc?
