Configure log4j Appender Properties
I'm using log4j1.2.8, is there anyway to check for a particular appender, say RollingFileAppender, whether it has a property, say datePattern programmatically? And then my check is passed, then i need to configure any values... Will this be possible with log4j API's? Your help appreciated.

Urgent Please--How to create different log files with different property files in same webapplication
Hi, I have a requirement to create different log files in same application.Our application will be used in a different web application.Even the other application is using log4j.We have our own log4j configuration property(WEB-INF/config.properties) file and separate log file in a particular directory(WEB-INF/logs/xxx.log). At present the problem is we are getting logs from other application to our log file. Our application(Giving as jar files) is under other application. For example our application is abc and others is xyz. The directory structure is webapps/xyz/WEB-INF where it contains xyz's log4j property file as well abc's log4j property file.abc's logs are supposed to go webappas/xyz/WEB-INF/logs/abc.log and xyz's logs are supposed to go different file(Which we dont know , exactly where it goes). But at present xyz's logs are coming into abc's logs means , they are coming into webapps/xyz/WEB-INF/logs/abc.log Can you please tell me how can get logs only from my applicaiton(may not be from my application..only from my classes). Its little urgent. Thanks in advacne.

Re: Urgent Please--How to create different log files with different property files in same webapplication
If xyz and abc are different web apps then moving log4j.jar and log4j.xml from common to WEB-INF/lib should keep the logs separate. If they are in the same web app then they probably have different logger name roots so you can configure each to use a different appender. (i.e com.abc uses one appender and com.xyz uses another appender).

Re: JUnit testing of output logged with log4j?
One option would be to using a test log4j.xml file that has appender
filters that filter out expected error messages. Maintaining that
might not be easy.
On 6/23/07, Bob Jacobsen [EMAIL PROTECTED] wrote:
I've got a bunch of code that uses log4j for logging, and a large
number of unit tests done with JUnit.
As is the nature of these tests, they test a lot of error conditions,
which results in lots of error and warning messages logged when
running the tests. Up until now, we just ignored those: If the
tests passed, nobody looked at the test output. If the tests failed,
then we started looking at the output for abnormal errors, which is
really a mess.
My co-developers and I would like to clean this whole situation up,
so that the tests run with no error or warning messages appearing in
the output log. But we still want to _test_ the conditions that are
errors, and in the code as it exists will throw those messages.
And we still want to see if _other_ error and warning messages start
appearing when the tests are run.
Anybody know how to Do This Right?
So far, we've got a couple suggestions:
1) Go through and find all the places where the error messages are
logged, and make then log through a service routine which can be
over-ridden. E.g.
class Mine {
void doSomething() {
...
if (bad) log.error(Oops);
}
}
becomes
class Mine {
void doSomething() {
...
if (bad) report(Oops);
}
void report(String msg) {
log.error(msg);
}
}
Then we can test it with
new Mine(){
void report(String msg) {
if (!msg.equals(Oops))
// assert error
}
}
The subclassing lets us intercept the error _before_ it gets to
log4j, and test it manually. But there's a _huge_ amount of this. It
seems a complete pain to do all this, and since we'd be putting in a
cover layer in front of log4j in each class, it seems far from a
best practice.
2) Instead of suppressing the good messages, learn to ignore them.
To do this, we'd just take a log from normal tests, and built into
our testing that we diff the current output with the normal log.
New or missing lines would be visible to the author; the same old
stuff would pass through the diff.
Of course, this is a maintenance nightmare. As code changes, we'd
have to keep the master error log synchronized, but it would be
easy for somebody to pass a Really Bad Thing as a new normal error.
This is currently the most popular choice, mostly because it doesn't
need to rework the existing code, but I really don't like it.
3) Do something via log4j itself.
I'm not even sure what I'm asking here, but can we somehow
programmatically access a stream of log4j log entries, and manipulate
it?
What I'm imagining is a test like this:
a) Push all existing stuff in log to whatever outputs are configured.
b) Temporarily stop output of log entries
c) run test
d) Check through log entries accumulated since (b), which come from
the test, and remove the ones that are expected (optionally, tell
JUnit to fail if something is missing)
e) Allow all other log entries to continue to their configured outputs
If there was some way to do this, we could have unexpected messages
still go to the usual places, as configured, but remove expected
messages from the log stream.
Is there a way to do this?
Or is there a better solution to the whole need?
Thanks in advance.
Bob

Can you better explain the relationship between abc and xyz? It
sounds like xyz uses abc as a library and that abc also runs by
itself.
Repository selectors might help.

But when XYZ starts using abc the problem occurs(XYZ is using Weblogic

Is there way to get separate the logs in a same application with

Re: Urgent Please--How to create different log files with different property files in same webapplication
Hi, Thank you for immediate reply.
The problem is little different here.XYZ and abc are in same application.XYZ
is using abc's jar files and jsps.
Our application(abc) have our own log4j configuration property file at
WEB-INF folder of XYZ(WEB-INF is common for both of XYZ and abc).
We are configuring log4j from java class file.We can not add/modify/delete
XYZ's log4j configuration property file.At present we are getting even the
XYZ's logs in our log files.
Please find our log4j configuration(abc's)

It(abc) works fine as a single application in tomcat6.
But when XYZ starts using abc the problem occurs(XYZ is using Weblogic
Application server).
Is there way to get separate the logs in a same application with different
log4j configuration property files.
Thanks Regards,

If they are in the same web app then they probably have different
logger name roots so you can configure each to use a different
appender. (i.e com.abc uses one appender and com.xyz uses another
appender).

Can you please tell me how can get logs only from my applicaiton(may not

Its little urgent.

We dont know exactly how log4j is handled at XYZ(They are our customers).But
in abc , we are referring a config file through our code.
Please find our java code.
==
package com.CK;
import java.io.File;
import org.apache.log4j.Logger;
import org.apache.log4j.Level;
import org.apache.log4j.PropertyConfigurator;
public class Log4jSetup

rPath = realPath;
}
public Log4jSetup()
{
String filePath =
rPath+File.separator+WEB-INF+File.separator+config.properties;
String logfilePath =
rPath+File.separator+WEB-INF+File.separator+logs+File.separator;
if( !(new File(filePath)).isFile())
{
System.err.println([CK]ERROR:Log4jSetUp::Cannot read

Re: Urgent Please--How to create different log files with different property files in same webapplication
So does only your customer have the problem of mixed logs? It sounds like they just need to change their config if they don't want mixed logs. But knowing how customers can be repository selectors might keep the logs separate without the customer changing their config.

Log4j Configuration
Hi Hopefully someone can help me. I want to configure log4j from a properties file. I am writing a little java application. I have several log4j appenders and everything works well. However I want the option to exit application if ANY of log4j configuration fails. By default I am seeing a warning message from Log4j but application continues to run... Do you know of a property to set for log4j that application exits if log4j properties are not correct? OR should I attempt this programmicatally.

RE: JUnit testing of output logged with log4j?
Bob --
Have you considered using an appender that doesn't write to any files
but simply collects all messages for later analysis?
Here's how:
1) Create an appender that simply stores all logging messages in a
static array. This appender should also provide static methods to (a)
retrieve all messages that were logged and (b) clear out the static
message array. Something like this:
package com.fwl;
import java.util.ArrayList;
import java.util.List;
import org.apache.log4j.AppenderSkeleton;
import org.apache.log4j.spi.LoggingEvent;
public class AppenderForTesting extends AppenderSkeleton {
private static List messages = new ArrayList();
protected void append(LoggingEvent event) {
messages.add(event.getRenderedMessage());
}
public void close() {}
public boolean requiresLayout() {return false;}
public static String[] getMessages() {
return (String[]) messages.toArray(new String[messages.size()]);
}
public static void clear() {
messages.clear();
}
}
BTW, fwl is my TLA for fun with logging.
2) Configure log4j so that this appender is attached to all loggers are
used by the target of your test. I'm taking a very simplistic approach
here and just attaching this appender to the root logger:
log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'
appender name=PrimaryAppender class=com.fwl.AppenderForTesting
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern value=%m%n /
/layout
/appender
root
level value=debug /
appender-ref ref=PrimaryAppender /
/root
/log4j:configuration
3) In the setUp method in your test harness, clear out the message list
that's used by the appender:
protected void setUp() throws Exception {
super.setUp();
AppenderForTesting.clear();
}
You also may want to include this logic in the tearDown method as well,
just to ensure that the message list is kept to a minimum.
4) In your test, after you invoke the method that should generate
logging messages, validate the actual output. Here is the code for a
simple class I wrote that just divides two numbers and a test harness
for that class.
package com.fwl;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
public class MyMath {
private static final Logger LOG =
LogManager.getLogger(MyMath.class);
public static double divide(int numerator, int denominator) {
LOG.debug(dividing + numerator + by + denominator);
try {
return (numerator / denominator);
} catch (Exception e) {
LOG.error(Unable to divide + numerator + by
+ denominator, e);
if (denominator==0){
LOG.error(You should never attempt to divide by 0);
}
return 0;
}
}
}
package com.fwl;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import junit.framework.TestCase;
public class MyMathTest extends TestCase {
public void testDivideDenominatorIsZero() {
MyMath.divide(2, 0);
String[] expectedMessage = new String[]{dividing 2 by 0};
validateMessages(expectedMessage);
}
private void validateMessages(String expectedMessages[]) {
// Build a list of expected messages.
List expected = new ArrayList();
for (int i = 0; i expectedMessages.length; i++) {
if (expectedMessages[i] != null) {
expected.add(expectedMessages[i]);
}
}
// Evaluate the actual messages that were recorded.
List unexpected = new ArrayList();
String actual[] = AppenderForTesting.getMessages();
for (int i = 0; i actual.length; i++) {
if (actual[i] != null) {
if (expected.contains(actual[i])) {
expected.remove(actual[i]);
} else {
unexpected.add(actual[i]);
}
}
}
// Fail if any expected messages were not found.
if (!expected.isEmpty()) {
StringBuffer sb = new StringBuffer();
for (Iterator iter = expected.iterator(); iter.hasNext();) {
sb.append(\n).append((String) iter.next());
}
fail(did not receive the following message(s): + sb);
}
// Fail if any unexpected messages were found.
if (!unexpected.isEmpty()) {
StringBuffer sb = new StringBuffer();
for (Iterator iter = unexpected.iterator(); iter.hasNext();)
{
sb.append(\n).append((String) iter.next());
}
fail(received the following unexpected message(s): + sb);
}
}
}
In the testDivideDenominatorIsZero method, we are only expecting the
message dividing 2 by 0. However, the actual test writes out two
extra messages when the denominator is 0:
* Unable to divide 2 by 0
* You
Use of NDC in chainsaw config
Hi there, I have several Tomcats running and generating logs. Within each Tomcat I have several Web-apps that generates logs. All these logs are going into chainsaw, However I want to differentiate the source of all logs. That is It should display in the log message it self that this log comes from ABC Web-app of Tomcat 1.. or this log is coming from XYZ web-app from Tomcat 2. (for example) I can use NDC for this but I dont know how to use it. Please help me in solving this problem. If possible please explain me by some relevant example.

logweb?

Not to discourage your work, but are you sure you aren't reinventing the wheel? http://www.codeczar.com/products/logweb/ There's certainly a few things that could be improved in LogWeb, such as support for multiple logger repositories instead of just displaying info about the default logger repository. But the core is there and works well. I wonder if you could build on it instead of creating something from scratch? Then again, maybe you have something much better and need to do it from scratch, in which case I eagerly await the fruits of your labor :-) Hi Jake, thanks for the hint - I wouldn't claim that I am not reinventing the wheel...that's one of my favourite hobbies ;-) I haven't worked with LogWeb yet, but according to their website, LogWeb is a web interface for configuring Log4J at runtime within a servlet container. The Live Demo on the LogWeb page isn't working and so far I have been too lazy to download and install it, but from what I've read on their page it is more about configuring the loggers of an application at runtime than about analyzing the logs themselves. As of now, I'm more interested in having the log files or our 60+ servers in a central database in a format which I can run queries against. That's why I responded to Ricardo's posting - to me it looks as if l4n is working in a similar direction, though in a different language and on a different level of granularity. Anyway: Thanks for letting me know, I'll take a look at LogWeb these days.
