RE: SMTP Logger

[George Sexton]

Here is a shell script to examine the logs for exceptions. I run mine every
five minutes.

        if [ ! -f $LOGFILE ]; then
                return
        fi
        if [ ! -e $MARKER ]; then
                touch $MARKER
        fi

        grep -ie exception $LOGFILE > $TMPFILE

Hi everyone,

Back to this again.. Any help would be very appreciated.

I'd created a custom logger that will email errors rather than log them
to a file system.

Unfortunately, if I add another <Logger className="..."> declaration to
server.xml, it will not use the existing Logger (FileLogger).  How can I
make it use both?

Optionally, I thought of extends the FileLogger, but it is declared
final, so this won't work.

How should I approach this?  Or maybe there is some class already part
of Tomcat that can do what I'm looking for?

I'm using Tomcat 4.03 under Redhat 8.

Thanks in advance.
Chris
