Hey James,
Your log use case remains me to mine... I wanted to use different log files
fore different cores... for the moment there's no way to separate logs in
different files (as far as I know). I sorted it using log4j. What I do is
send the log data to the linux syslog (using syslog appender). Once the data
is there I just coded some scripts to send it wherever I want. You could
send your data to syslog and parse that file... and depending on if you find
the message TRACE, ERROR, DEBUG... just send that lines to the files you
choose.
This worked for me (not 100% coz there are log messages without the name of
the core) to separate logs depending on the core name without doing any
hack. In your case would work even better coz you always have the log level
in the message.
If someone knows any better way to do that please let me know...
