Re: Custom Syslog Format: Appending Exceptions?
Hi, In my case I created a SyslogWrapperLayout which can wrap any other layout, so I put PatternLayout inside SyslogWrapperLayout. As far as I see that's the only way to get cusomizeable Layout for syslog. Ah, and one more thing, I don't use SyslogAppender, but a simple SocketAppender with SyslogWrapperLayout, it works great, Obviously that's not a standard way, but that's how log4j2 should work ;-) Tomek On Mon, May 13, 2013 at 8:38 PM, Jason B makotothedra...@gmail.com wrote: Looking around at the Syslog support, and I noticed that exceptions aren't being sent across the wire.

Re: Need help: Steps in your INSTALL doc failing
No, Mary is just running an example from the install documentation. And since
the code is calling BasicConfigurator.configure(), there is no need for a
config file in the classpath (though it is generally recommended to use a
config file rather than configure via code).
Mary, please provide an example of your java command line when you run this.
It should look something like...
java -cp log4j-1.2-17.jar Hello

You seem to be using log4j-1.2.
Then you should only need the one jar.
You also need a log4j.properties or log4j.xml file in a directory that is in
the classpath. The site should have some sample config files.
In your code, I don't think you need to call BasicConfigurator.configure();
I think you can safely remove that line; log4j will pick up your config file

You can now test your installation by first compiling the following
simple program.
import org.apache.log4j.Logger;

public class Hello {

I understand how CLASSPATH works, etc. I can get it to compile but
even if I again (with option -cp) specify exactly where the .class file
is
that it just created from the compile, it still can't find what it
needs.
Depending on where I've put things and what I tell it, I get one of
these
failing results when I try to run the executable:
(1)
java.lang.**NoClassDefFoundError: org/apache/log4j/Logger

Notice I added the current directory to the classpath. Change the
classpath separator character to a colon if needed.

No, Mary is just running an example from the install documentation. And
since the code is calling BasicConfigurator.configure(), there is no need
for a config file in the classpath (though it is generally recommended to
use a config file rather than configure via code).
Mary, please provide an example of your java command line when you run
this. It should look something like...
java -cp log4j-1.2-17.jar Hello

Mary,
Gary was referring to log4j-2.0. While generally more awesome (ahem), it
does need those 2 jars to run.
You seem to be using log4j-1.2. Then you should only need the one jar.
You also need a log4j.properties or log4j.xml file in a directory that
is
in the classpath. The site should have some sample config files.
In your code, I don't think you need to call
BasicConfigurator.configure();
I think you can safely remove that line; log4j will pick up your config
file from the classpath.

Hey - thanks for the quick reply! Ya know, I read that bit
but the jar file I have is named log4j-1.2-17.jar, and I thought
it comprised everything. When I downloaded the code, that's
the only jar file there was. Clearly, I was delusional! I'll go
look for the corresponding API and core jar files...
Thanks again!

Hello -
I can write, compile, and successfully run a Java program
to look at a .jar file and list the classes defined therein, but
I can't for the life of me get your Using log4j java code shown

Perhaps there's some other magic that needs to happen to get

Burst Filter - Use to limit messages sent over a specific period?
I'm attempting to leverage a burst filter in my application. I wish to log errors and send e-mails any time we log an error. The main thing is, I don't want to send more than a few e-mails in a given time period (say, one per event per fifteen minutes), to avoid overwhelming my inbox with these error events. Burst Filter seems appropriate for this role, but the documentation is lacking. For instance: - If I want a filter to accept only those events that happen after the threshold, but rest for that fifteen minute period of time, how would I accomplish this? The configuration is less than intuitive here. - What is the role of TimeBasedTriggeringPolicy /? It's not mentioned anywhere on the site, and only by digging in the source could I actually determine what it's supposed to be doing. It's also listed in every example for filters on the site. Thanks for clearing up any confusion. - Jason Black
Re: Custom Syslog Format: Appending Exceptions?
I find this interesting...you had to go back a few levels to implement this sort of custom behavior. I'd love to see your patches, since I'm curious if this can be incorporated into the SyslogAppender as opposed to going one or two levels above it. - Jason Black On Tue, May 14, 2013 at 2:10 AM, Tomek Kaczynski tomek.kaczyn...@gmail.comwrote: Hi, In my case I created a SyslogWrapperLayout which can wrap any other layout, so I put PatternLayout inside SyslogWrapperLayout. As far as I see that's the only way to get cusomizeable Layout for syslog. Ah, and one more thing, I don't use SyslogAppender, but a simple SocketAppender with SyslogWrapperLayout, it works great, Obviously that's not a standard way, but that's how log4j2 should work ;-) Tomek On Mon, May 13, 2013 at 8:38 PM, Jason B makotothedra...@gmail.com wrote: Looking around at the Syslog support, and I noticed that exceptions aren't being sent across the wire. I understand that there may be some limit to how much data we're sending across with Syslog via TCP, but I was curious if there was any custom support for formatters with exceptions. I came across this old JIRA for that support: https://issues.apache.org/jira/browse/LOG4J2-136 ... and looking into RFC5424Layout, I see that it could be added, but I'm not sure if our setup is configured properly to make use of it. - Jason Black
Re: Adding appenders programatically
What is the recommended way of adding appenders in log4j 2. In older version we were able to do Logger.getLogger(theCategory).addAppender(appender). Thanks!
