Hello,
I'm a new user to the mailing list, so my apologies if
my questions are
frequently addressed. Please direct me to the
appopriate forum or
resource if possible.
1. I'm working with a J2EE application using log4j. We
have multiple
instances of an application server running. Originally
we were using
the
same application output file (with
DailyRollingFileAppender) but we saw
resource contention issues with the single copy of the
file, especially
at midnight when each app server attempted to roll it
over. Our current
fix is to extend DailyRollingFileAppender and override
the setFile()
method from FileAppender so that the log file name
incorporates the
server name. Is there a better way to do this?
2. There is at present only one appender logging
information, and it is
quite verbose. I'd like to add another appender
temporarily (for
alerting purposes) that will register only error
messages. However, I'd
like to be able to configure which error messages are
logged using the
run-time configuration file, instead of adding Filters
programmatically.
Is it possible to filter error messages by
text-matching based on
configuration files? (we're currently using flat text
key-value pair config files)
3. I have come across the following line in a
configuration file:
log4j.category.log4j.Sort=INFO
I'm not sure what this .Sort property is doing, and I
cannot find it
used in any example configurations in technical docs
on the web. Any
idea what this is? My assumption is that it is being
ignored by log4j
(as it is unrecognized).
Thank you kindly for your time and help.
Sincerely,
Elliott Yates.
