RE: Problem changing log level at runtime

This does not happen for me. I use 1.2.6 and make extensive use of changes
at runtime. I use it to enable debugging on parts of the system without
having to take the system off line.

Switching from and to Debug does not present a problem.  I just use the
setLevel() methods.

Do you have any more specifics?

Hi all,

At runtime , when I change the log level from  high (say info) to low (say
debug) , log4j functions properly.
But when i try to change from  low (say debug) to high (say info) it has not
affect i.e. log4j continues to be at the  low (say debug) log level. Does
any one know why this happens? Is this a bug ?

Thanx in advance !!

SNMPTrapAppender v. 1.2.3

Greetings,

I’m starting the New Year off with a release of the SNMPTrapAppender.  New
in this release is an additional implementation of the SnmpTrapSender
interface which uses the open source NetSNMP command line tools to send
traps.  I wrote this primarily as a proof-of-concept – several people have
written me asking how this task might be accomplished, usually because they
were interested in sending traps using OpenView/NetView’s “sendtrap” command
line tool.  The new “NetSnmpCommandLineTrapSender” should serve as an
example of one way that this could be accomplished.  There are doubtless
other, better ways!  One thing I noticed in my testing is that the
performance is not good, compared to using one of the Java libraries like
JoeSNMP, but given the context switching, JNI thunking and whatnot that goes
on behind the scenes, I didn’t find this surprising.

You can get the latest version, as always, at:

http://www.m2technologies.net/asp/snmpTrapAppender.asp

Cheers,
Mark

RE: Problem changing log level at runtime

I donr use setLevel() function rather i use Propertyconfigurator.configure()
method to change the properties at runtime. Does that make any diference??

custom properties in log4j

hi everyone,

we've extended log4j with some custom pattern layouts that print the name of
the (web)application ( in addition to the logger ) logging the event.

is there a way in log4j to set the application name as a property and have
it visible to in our extended log4j classes?

we're planning on setting this property (app name) in a context listener and
later retrieving it in our custom pattern layout classes.

thanks!

david

MDC & ObjectRenderer problem


Hello,

It seems to me as if Objects which you put in an MDC are not correctly 
rendered. That is, they get rendered simply by calling the toString method 
instead of using the renderers registered.

I suppose the problem resides in helpers/PatternParser.java:

  private static class MDCPatternConverter extends PatternConverter {
    private String key;

    MDCPatternConverter(FormattingInfo formattingInfo, String key) {
      super(formattingInfo);
      this.key = key;
    }

    public
    String convert(LoggingEvent event) {
      Object val = event.getMDC(key);
      if(val == null) {
        return null;
      } else {
        return val.toString();
		^^^^^^^^^^^^^^
      }
    }
  }

But don't ask me how to fix it :-)

RE: MDC & ObjectRenderer problem


Hello, I got the following from log4j

log4j:WARN No appenders could be found for logge
(com.spectel.cvapi.modapi.ModAPIConference).
log4j:WARN Please initialize the log4j system properly.

Here is the property file I used. Is anything missing here caused above
warn or something else ?

I appreciate any advice.

RE: Warning from log4j initialization

I was having the same trouble, and it turned out to be a class loader issue.
I had two separate web apps, each with its own log4j.properties file. Both
apps had log4j.jar in their respective lib directories. But the problem was
that i also had a log4j.jar in the jdk_home/jre/lib/ext directory, as well.
Removing the log4j.jar from the ext directory (but keeping the jar in each
web app's lib directory) solved my problems.
