Hi Bogdan,

i don't think this is a good way to solve this. An easy way to seperate the 
log messages generated from the script to the ones from the server would be 
just to add a prefix.

Ok, i'll try to give each log levels a meaning:

DBG:
used only for debugging, don't need to be understandable from users, provide 
an insight into the inner working of the server, e.g. memory management, 
parsing, state of internal module function

INFO:
used for informational messages that are emmited during normal operation, 
should be understandable from users, to give an indicator about the performed 
operations of the server, e.g. proceeded messages, routing descisions, 
startup informations

NOTICE:
used for informational messages that are generated during abnormal, but not 
critical operation conditions

WARN:
used for warning messages that are emmited during abnormal and less critical 
operation conditions, for example a file could not found and an empty module 
configuration will be used, a required part of a message is missing and the 
code tries to continue with some degration

ERR:
used for error messages that clearly indicates a problem, but this could be 
handled in the server, e.g. memory allocation error, failure to access the 
database, network error

CRIT:
used for critical messages that clearly indicates a problem, which could not 
be easily handled in the server

ALERT:
used for conditions which could be handled from the server, and will lead to a 
shutdown or crash.


I think perhaps one or two levels are superfluos here. NOTICE is not that much 
used, and i had a hard time to seperate this from the INFO and WARN. ALERT is 
also not much used, and i also think the existing callers could just use the 
CRIT level. What do you think, perhaps this is something for 1.5?

Cheers,

Henning
