Newbie questions
Hi,
I am a newbie of log4j.
1. I would like to log the messages to NT event log. I know that the
log4j package come with a dll file. I tried to use it. But I find
that the Source is always "log4j", Type is "Error", Category
is "4096". How can I change these values(Type, Source, Category,
Event and User)?
2. When should I use NDC/MDC?
3. When should I use filter?
4. I am gonna to buy the complete manual of log4j. Would like to get
some feedbacks on it.
5. I have an application, I would like to log the fatal errors to nt
event log and the all the warning messages and fatal messages store
in a file. Should I define as follow?
log4j.rootLogger = FATAL, A1
log4j.rootLogger = WARN, A2
where A1 is nt event appender
where A2 is daily rolling appender
6. I have a few web applications running in a JVM. Can each
application has their own log4j properties files?
Thanks in advance.
Fanny

Re: Newbie questions - NT Event log
Posted by toffeemak <to...@hotmail.com>.
HI,
Thanks for your reply. Actually, I am able to log the message to NT
event log. But the values in Type, Source, Category, Event and User
columns on Event Log viewer are always the same. Seems that the log4j
api only able to change the message. Since my applications need to
have different values for those columns. Any idea how to do it?
Regards,
Fanny

'Fraid I can't answer all your questions, but I'll do the ones I can. I
tried out NT event logging a while ago, so I've gotten it working, but my
memory is a little fuzzy on the subject.

That sounds like an error in configuring the appender. Check that the
directory with the .dll file is on your Windows path, and see the config
remarks below.

I think that should be:
log4j.rootLogger = WARN, A1, A2
log4j.appender.A1.threshold=FATAL
Hope that helps!
