[PEAK] peak.running.logging

Hey everyone,

I'm still playing around with PEAK - it's giving me flashbacks to 
learning how to use vim or emacs - the learning curve is pretty steep, 
but every hurdle I get over seems to bring a little 'Aha!' moment.  :)

I've think I've got a basic understanding of the peak.model.elements 
and peak.model.features - at least the bits that are covered by the 
bulletins tutorial.  I can now get domain objects to pop out of my data 
managers - so that's good.

I'm having a bit of a tough time figuring out what's going on with the 
peak.running.logs though.  How do I go about customizing the log 

In particular when I do something like this:

log        = binding.Obtain('logging.logger:storage.AddContact')

Where does the "storage.AddContact" go?  In fact, what is it used for?  
I was under the impression that it's a logical name for a logger and it 
should show up in the log messages.

I was expecting something like this:

Nov 27 14:20:51 dhcp139 storage.AddContact [3926]: Creating 
sqlite:///tmp/sextant.db using DDL from 

instead of :

Nov 27 14:20:51 dhcp139 PEAK [3926]: Creating sqlite:///tmp/sextant.db 
using DDL from /Users/victorng/dev/sextant/src/sextant/sqlite-ddl.sql

I've also tried subclassing the peak.running.logs.LogFile class and 
changing the publish method, but I"m not sure how to get peak.logs to 
use my custom logfile logger.  Here's what I've put in my initial 
configuration (based on the bulletins example).

* = sextant.logs.SextantLogFile(filename='/usr/local/log/sextant.log', 

The above throws an error saying "sextant" is undefined - how do I 
declare an import using the config files?  Or am I running in 
completely the wrong direction here?  It feels like I'm doing something 
horribly wrong.

My ultimate goal would be to have a logger that takes in a couple 
arguments so that I can get event records with event ID numbers in the 
log.  Something like this:

2003-11-27 14:20:51,dhcp139,storage.AddContact,555,777,"Creating 
sqlite:///tmp/sextant.db using DDL from 

where 555 and 777 are status code passed in when call the logging
