Howdy,
You can use sockets (appender / receiver / or hub) the whole way.  You
can also use the JMSAppender/JMSSink.  You're right this is doable using
log4j.  Check out how chainsaw works.

Log4j 1.3 will have even more support for this, via pluggable Receivers
for logging events.

Subject: is there anything in log4j that can enable me to do this.?

Hello people!

I been wondering about a requirement i have.  I am sure it can probably
be
done using log4j using Socket/JMS Appender???
But thought i check if its possible to do this in log4j (i am no expert
in
the advanced topics of log4j):

-  Receive alert messages over TCP/IP from another application.

- Format the information as required and send it to the appropriate 3rd
party tool.


Am i right We can do this using the Appenders i mentioned
above??//


Thanks for any help you can give.

 Thanks for ur advice Yoav,
 
  pluggable Receivers for logging events... whats this???
 

Hi Michael, 

Receivers are the sibling of Appenders.  Appenders take an event from Log4j
and take them outside the log4j environment (to a file, socket, JMS topic,
SMTP etc).  Receivers take an external event (say, from a Socket) and push
or 'post' them into their local Log4j environment.  Receivers are great for
getting hold of Log4j events from a remote location.  Chainsaw uses them
extensively.

If Chainsaw wasn't enough to help you monitor events from a remote location,
you could always mimic something by writing it yourself.  Write a program
that configures Log4j to use a Receiver to suck external events into the
programs local log4j environment, then configure appenders in that same
local log4j environment configured to catch the events you're interested in
and react accordingly.  (this is all Chainsaw does! :) )
