[Openinteract-dev] what to log and when

[Chris W. <ch...@cw...>]

I've been rewriting the error module to work with the filesystem 
instead of the database. That part is (mostly) done, but my initial 
idea of hooking this to log4perl with a custom appender has hit a 
little snag.

  - If we set the threshold to 'FATAL' we don't store anything -- 
nothing is logged with a 'FATAL' level.
  - If we set the threshold to 'ERROR' we store a ton of messages, too 
many to be useful.

This is my fault for not setting guidelines in the beginning as to what 
the different logging levels should mean. I don't have a good feel for 
how other people do this, so before I go through and try and make 
everything at least roughly consistent I'd like to hear what you think:

What are appropriate messages to log at these levels?

   DEBUG
   INFO
   WARN
   ERROR
   FATAL

FWIW, related JIRA issues are at:

   http://jira.openinteract.org/browse/OIN-46
   http://jira.openinteract.org/browse/OIN-35

Thanks,

Chris

PS - Would it be useful to post here a periodic status message as to 
how OI2 is doing? In theory this should be on the wiki and I'll put it 
there if people find it useful, but I didn't get much feedback...
