Sorry, I think I got misunderstood.  I have no problem with
levels/thresholds when logging from the app.

What I want to do is generate an additional log message from INSIDE the
appender code, WHILE it is about to process an application message.=20

I'm not an expert on Log4j, but recently had a similar requirement.  I
didn't want debug messages appearing on the console.  So on my console
appender, I set a threshold like this:

log4j.appender.CA.Threshold=3DINFO

I got that from somebody else on this list.  This way I only see INFO
messages and above on the console and I see everything in my log file
from debug up.  If you did the same but set the threshold above WARN,
the console will only show messages above WARN, however you won't see
anything less than or equal to WARN on the console.  Don't know if that
helps.  I think the log4j configuration in XML allows for a min and max
threshold.

What is the best way to send a message to the log from inside the
Appender itself?  (separate from the message that the appender is
currently processing)

Why do I even ask this?  My appender checks disk utilization every hour.
I'd like to record the % of disk utilized in the log.

I tried using LogLog.warn(), but it puts the message on the console, not
in the log file generated by the appender.  I could probably add it
manually to the code that writes to the file, but that feels messy...
and I suspect that there's built-in log4j functionality for what I want
to do.
