Add Notice level

[smithwinston]

It would be nice to have an additional level between Info and Warning Notice. I tend to use logging as follows:

• Notice: System start/stop, significant-but-normal events
• Info: Detail: User connected, transaction applied etc.
• Debug: In depth debugging/tracing, e.g. packet dumps

I usually would have the default log level set to Notice and have Errors, Fatal and Panic logged to a remote server for analysis.

This is a pretty narrow use case, and not something that's come up before. It won't be added to Logrus for now. Thanks for the suggestion!

I would also like to see this Log level be introduced into logrus. I too, like to use Notice for errors that aren't as critical and not uncommon to see in a normal workflow. Warning and Error are usually too severe, and Notice is helpful.

@kellydunn it's planned for 1.x that you can add any logging levels you want, as levels will simply become fields, and formatters will support that field or they won't.

@sirupsen: is more information about 1.x available somewhere?

[sirupsen]

@jonhoo not yet, I'm still thinking about it. But it'll be much more customizable, msg, levels etc. won't be special, and center around Go contexts (see the package).

[jonhoo]

@sirupsen sounds great. Being able to have multiple debug levels, and being able to use the logging library sensibly in two different packages that are both used simultaneously, are two of my biggest concerns atm.

+1 for customizable log levels. A generic Log(Level, string) would fit in nicely IMHO.
As for "fixed" levels I have 2 suggestions:

#1:
Info
Verbose
Debug

#2:
Info
Debug
Trace

Personally, I prefer the # 2.

Did this ever happen and land in master?
