Sorry, I think you may have missed my point. The event log in Windows is specific to \
the installation only. To me, recording things that have taken place on an a \
different machine in a remote systems event log doesnt look like good design.
Given that you have a lot of different systems you want to log with different logging \
criteria, wouldnt logging to a data base be a more prudent move?
The ability to view remote logs isnt new with Windows 2008, its been around for a \
while now. Bear in mind that this isnt the event log, its called the event collector \
and is a seperate service. You need to decide which will be better for you - if you \
want to rely on this (i.e. you have a tool that needs the Event Log) then you are \
going to have to look into this, however if you want a flexible logging system, then \
you may want to spend more time with log4net.

Subject: RE: Using log4net to write to remote windows event log
Thanks Karim.
In my case I have a number of systems distributed on different computers in a test \
environment and I would like certain errors (that would cause my application to stop) \
to also go into a central event log in order to be able to only inspect one event \
log. Emailing in my case is not something that I would use.
The fact that Event Log is a windows technology it not an issue, this application is \
windows only, log4net supports Event Log, even if not at it's full capabilities. In \
order to make the Event Log appender be able to write to a remote Event Log you only \
need about 5 lines of code changed. But of course, I'm not sure about the performance \
penalty and I don't know why this capability was "postponed" in the appender (this \
might clarify this).
Also there is a appender that is able to write to remote sinks, RemoteSyslogAppender, \
which is mostly Linux only, so using a remote sink is not something new. Windows 2008 \
seems to have the ability to collect logs from other computers, so somehow they have \
thought about something like this.

This isnt something I have ever needed to use log4net for, but there are two \
possibilities for you: RemotingAppender and UDPAppender. Both of these appenders \
appear to be able to deliver messages to remote apps, at least this is what the \
log4net page on config examples suggest: \
http://logging.apache.org/log4net/release/config-examples.html
There is also a SMTPAppender that could also help you out.
However, I dont think there is anything ready made for you that will enter these \
events onto another systems event log. If this is a Windows environment, then it isnt \
a great idea anyway. If you think about it a bit, the event log is used for the \
system upon which the OS and other applications are running. To me, it makes very \
little sense to log events from other systems here.
Have you considered simply using the ADONetAppender to log events to a database \
somewhere? This, to me at least, would be a better way of logging events - but then \
again I dont really know what it is you are trying to do.
