And, for those who like concrete examples, here's how to modify
local.properties to route all messages to the standard log file and, in
addition, send any warning and error messages to an email address:
logging.threadedlogger.listeners=filelogwriter,emailwriter
logging.emailwriter.class=allaire.jrun.logging.SmtpLogWriter
logging.emailwriter.from=JRun
[EMAIL PROTECTED]
logging.emailwriter.host=myMailHost
logging.emailwriter.loglevel=warning,error
The first line (logging.threadedlogger.listeners) augments the default
behavior (which is to send messages to the log file) by also sending each
log message to the 'emailwriter'.
The rest of the properties setup the 'emailwriter' logger (see Chapter 37 of
"Developing Applications with JRun"). Whenever messages with the loglevel of
'warning' or 'error' are received an email will be generated and sent to the
corresponding address. The subject will be the message and the body will
contain the same information found in the log (timestamp, message, stack
trace, etc.).
Hope this helps,

Bin,
JRun has built-in features that provide information that can be used for
isolating bottlenecks, identifying threading issues and identifying areas of
your application that cause performance or reliability failure. They
include:
� Metrics -HTTP request throughput
� The Interceptor -(JRun Instrumentation)timings for method calls
� Logging -logging available (file, email, db etc.)
JRun includes a logging utility that requires little overhead that enables
you to forward run-time information to a file, the screen or an email
message.
For more information on these features see Chapters 36(Metrics), 37(Logging)
and 39(Instrumentation) in Developing Applications with JRun.
HTH,
Robin

Subject: Tools monitoring log file
Hi List,
I am wondering if there is any tool for me to look through Jrun log files to
find some entry and send an email to me if it finds a new entry of some
Exception.
More specifically, I want it to check all Jrun logs once an hour and if it
finds exception, it send me a email. I do not know if Jrun itself has such
a tool.
Thanks,
Bin
