Re: Logging complete exception trace.

[Remko Popma]

Hmm, your source code looks correct. In your config, you could probably remove 
the named logger entry. 
>>> 
>>>   
>>>   


The  alone is sufficient I think. 
But this won't solve the issue...

Do you see this behavior everywhere or only in some places?
If you replace %ex in your pattern with %tEx, location info will be added to 
the output. This may help pinpoint the code that generates the log entry so you 
can double check it...

Sorry I don't have a better answer.

Re: Logging complete exception trace.

[Remko Popma]

Sorry, I made a mistake: %t prints out the Thread. Please replace %tEx with 
%xEx. Can you show the output of that?

Also, what version of log4j are you using? 2.3?

Re: Why is log4net not more similar to log4j(2)?

[Ralph Goers]

Nick,

You ask and discuss on the dev list.  The number of developers isn’t that large 
so it should be readily apparent if there is interest.  That said, Log4j 1.x 
was pretty dormant when I started working on Log4j 2. I worked for almost 18 
months before I committed anything just because I wasn’t really sure about 
anything. After I had something to talk about I committed it to an experimental 
branch where others could start contributing their ideas.  I think that has 
worked out pretty well.

Since you don’t currently have commit rights you might either start something 
on github or it may be possible to create a new git repo for log4net 2 and give 
you access to that. That would be a bit unusual but not unheard of.

Ralph

This is certainly part of the reason.  log4net was started as a port of
1.x a long time ago.  The developers (long before I joined) added some
deviations that look closer to what log4j 2 is doing (XML
configuration).

Incidently Dominik started a discussion about log4net 2.0 on the dev
list[1] and some people expressed interest.  Any hand that can offer
some help is more than welcome, so please come over and join.

Re: Logging complete exception trace.

[Kiran Badi]

Thanks Remko for reply, I think that's how I do it.

 Please see below the way I use it. I am on log4j2 and I have log4j-api,
log4j-core and log4j-web jars in the lib directory of my web app.

I import these 2 packages
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;


Create a static instance

 static final Logger log = LogManager.getLogger(myclass.class.getName());

then do use it in class file

  catch (Exception ex) {
 log.error("Got the exception", ex);
}

I was under impression that this should log the complete trace, but its not.

Any ideas as what I am missing ?

Re: Why is log4net not more similar to log4j(2)?

[Ralph Goers]

To answer your last question, at the ASF the project committers decide what 
they are going to do. They make decisions by discussing their ideas on the 
mailing list.  In some ways, the ASF is a “do-ocracy”. You can make all the 
recommendations you want, but ultimately it is up to whoever implements it.

Take a look at http://www.apache.org/foundation/how-it-works.html 
.

Re: Logging complete exception trace.

[Remko Popma]

In your application, 
do not use logger.error(exception);
but use logger.error("some message", exception); instead. 

The first form will take the exception object as an object and calls toString() 
on it, which is not what you want.

That's what I meant with log4net2 should take as much knowledge as possible
from log4j2.

Apologies, it's quite late in my timezone and I seem to be unable to wrap
my head around this sentence. :-) If it means what I interpreted the answer
is:

It has been and will always be something between "what it should be" and
"what gets done". With more time (in the meaning of working time and thus
hours of spare time) there is more room for "what gets done" and thus help
is always welcome. :-) Getting involved further puts you in the position to
decide "what gets done" with even a few more options (the cool one "how it
is done" is among them).

But if the meaning is something else, would you be so kind and rephrase
your point, please?

This is not entirely true and not at all that dramatic. The scale is
different, yes, but not inversed. Here comes a comparison of a few almost
random samples:

level, log4j, log4net
ALL; -2147483648, -2147483648
DEBUG, 1, 3
INFO, 2, 4
WARN, 3, 6
ERROR, 4, 7
FATAL, 5, 11
OFF, 2147483648, 2147483648

I did not know this, but the log level constants should be the same across
all members of the ASF logging family and therefore I've queued this as
issue LOG4NET-476.

Re: Logging complete exception trace.

[Kiran Badi]

Ok here is the pattern changed  I tried

%d{dd/MMM/ HH:mm:ss,SSS}- %c{1}: %m%tEx%n

After doing this, I got this in logs,

18/Sep/2015 17:23:05,421- myclass: Got the DAO ExceptionError inserting
into database. Parameter index out of range (24 > number of parameters,
which is 23).http-bio-8084-exec-35Ex


All my classes are giving single line exception message,

How do I debug this issue now ?

RE: Why is log4net not more similar to log4j(2)?

[Nicholas Duane]

I looked over the thread you included below.  I can't tell from that whether 
the suggestion was to port log4j2.  Not sure if the comment about starting 
log4net 2.0 "from scratch" is an indication of having it be a port of log4j2.

In my mind the biggest benefit would be to have the same architecture/feature 
set running on both linux and windows.  Of course it would also be great if the 
releases were synchronized.  I know a big gripe of log4net is that it's not 
getting rev'd.

I would be interested in helping if the goal is to bring log4net in sync with 
log4j2.  And by this I guess I mean port as that would seem the easiest and 
safest path to the goal.

I haven't worked on any open source project in the past.  I'm curious, how does 
this work?  Who's coordinating and making the decisions?

Thanks,
Nick

Re: Why is log4net not more similar to log4j(2)?

[Douglas Wegscheid]

is something like jni4net an interim solution? Use log4j2 as is, just
expose the logging methods to .Net? All the guts would still be log4j2.

Yes, a little icky and clunky (and possibly not even viable), but just
throwing it out there

RE: Why is log4net not more similar to log4j(2)?

[Nicholas Duane]

I'll take a look at the link.  So if I'm interested in helping, if in fact the 
goal is to port log4j2 to .net, then how do I know whether anyone who would 
make that decision is even thinking about that, if they are thinking about it 
how do I know if they've decided to move forward, and when that decision takes 
place?  Do I just put my name on a "waiting list"?

Thanks,
Nick

To answer your last question, at the ASF the project committers decide what 
they are going to do. They make decisions by discussing their ideas on the 
mailing list.  In some ways, the ASF is a “do-ocracy”. You can make all the 
recommendations you want, but ultimately it is up to whoever implements it.

I think I read somewhere that log4net was a port of log4j 1.

This is certainly part of the reason.  log4net was started as a port of
1.x a long time ago.  The developers (long before I joined) added some
deviations that look closer to what log4j 2 is doing (XML
configuration).

Incidently Dominik started a discussion about log4net 2.0 on the dev

RE: Why is log4net not more similar to log4j(2)?

[Dominik Psenner]

Given that both c# and java are very similar in both syntax and interpreter
that runs the bytecode, users of log4j can expect a very steep learning
curve when starting with log4net. Despite that log4net is based on log4j
and thus may lack some things found in log4j2. These missing things and the
support for ancient versions of the .net framework caused my desire to
start off log4net2.

So, yes, log4net2 should be based on log4j2 and reuse all the knowledge
that has been generated within log4j2. It would be stupid to do otherwise.

All this can be achieved only with a rewrite. Im no fan of code generators,
therefore, translating java to c# will be no option to me. In the end we
would probably have to invest more time in analyzing and bugfixing
generated code.

The downside of a rewrite is that it is a lot of work and thus it takes
time. I can invest about an hour a week. Currently this hour goes into
responding questions on both user and dev mailingist. To make this real a
lot of helping hands will be required. Volunteers are welcome!
