I created an application with different levels of logging. Now I got into a situation to log errors to dev team and fatal to dev and admin. here is the code I had given a try..
log4j.rootlogger=DEBUG, email, email2
#email
log4j.appender.email=org.apache.log4j.net.SMTPAppender
log4j.appender.email.SMTPHost=smtp.company.com
log4J.appender.email.Threshold=error
log4j.appender.email.From=emailNotification
log4j.appender.email.To=dev#company.com
log4j.appender.email.SMTPUsername=user#company.com
log4j.appender.email.Subject=email Notification from Tomcat Server
log4j.appender.email.layout=org.apache.log4j.PatternLayout
log4j.appender.email.layout.ConversionPattern=%d%d{dd MMM HH:mm:ss}%p %t %c - %m%n
log4j.appender.email.BufferSize=1
#email2
log4j.appender.email2=org.apache.log4j.net.SMTPAppender
log4j.appender.email2.SMTPHost=smtp.company.com
log4J.appender.email2.Threshold=FATAL
log4j.appender.email2.From=emailNotification
log4j.appender.email2.To=admin#company.com, manager#company.com
log4j.appender.email2.SMTPUsername=user#company.com
log4j.appender.email2.Subject=email Notification from Tomcat Server
log4j.appender.email2.layout=org.apache.log4j.PatternLayout
log4j.appender.email2.layout.ConversionPattern=%d%d{dd MMM HH:mm:ss}%p %t %c - %m%n
log4j.appender.email2.BufferSize=1
when I run my application with
logger.error("error:"+e);
it was triggering email to admin and manager also. so even it is error/fatal it is triggering to all.
any trick? can someone help me.
There is a typo in "log4J.appender.email2.Threshold" (letter J is in CAPS). ERROR is the default value, so it doesn't matter in the email1.
In case someone is copy-pasting this code snippet...

Can anyone please let me know filter properties for a package where
I want to separate the logs in two different logs files. Below is the configuration which I am trying use but its not working. I want deny logs
based string like 'UserMgmt-' and allow rest logs in log1 appender and allow only log2 appender allow 'UserMgmt-' and deny rest allow logs.

Summary
We're struggling with enabling log4j's TRACE level in a custom Documentum DFS application. The application runs on Tomcat 7.0 and uses Log4j 1.2.13, and is packaged as a WAR archive.
We have an appender called CustomServiceAppender that works just fine with all the other levels, i.e. DEBUG and upwards. During development we have this appender configured for the DEBUG level, and for production we change it to INFO or WARN. The logging then behaves like we expect (it limits the logging).
However we have written some code that logs at the TRACE level that we want to see in our logs. We've tried restarting, redeploying, deleting cache, checking log4j and commons-logging versions (they are 1.2.13 and 1.1.1, respectively). Also, there is no XML configuration file, and we know that our properties file is being picked up.
We use the default logger from DFS, namely the DfLogger class.
Changing the configuration - why doesn't it work?
In log4j.properties we change the following line from
log4j.logger.com.mycompany.services=DEBUG,CustomerServiceAppender
to
log4j.logger.com.mycompany.services=TRACE,CustomerServiceAppender
... which does not work! However, the following does work:
log4j.logger.com.mycompany.services=INFO,CustomerServiceAppender
What's happening here? Why can't we enable TRACE?
log4j.properties

****************************************************************************************
How to know in log4j , that ERROR level is triggered. In my code I have written like If an exception occurs i.e if an ERROR level is triggered then I will show log file path in console and wont show any message for other levels.
In Log4j you can configure different levels in the log4j.properties or xml file which ever you choose to use.
There is some predefined pattern with the error levels and runs from lower to upper.
Lowest id Debug its in this sequence.
1.Debug
2. Warn
3. Error etc
So if you want only Error messages then configure the Error level to Error. you wot get Debug and Warn
If you configure Debug you get everything
Ex.
<logger name="org.springframework...">
<level value="error" />
</logger>
This is the point of separating the code from the configuration.
E.g., your code could look like this:
try {
someMethod();
} catch (SomeException e) {
log.error("Error!!! " + e.getMessage());
}
And in your log4j configuration, your configure your log to output only ERROR level messages:
log4j.rootLogger=error, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# Just an example of a pattern layout
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
I have a debug,info,warn,error logs in my code. But i want to print only info,error logs in my console. I want to store all the logs in a file. Can anyone suggest a way.
I trie with
log4j.rootLogger=debug,R1,R2
log4j.appender.R1=org.apache.log4j.ConsoleAppender
log4j.appender.R1.layout=org.apache.log4j.PatternLayout
log4j.appender.R1.layout.ConversionPattern=%d{dd/MM/yy kk:mm:ss.SSS} %-5p [%t] %x (%F:%L) - %m%n
#OAPIFacade front logs
log4j.appender.R2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R2.File=app/log4j/prop/log4j.log
log4j.appender.R1.DatePattern='.'dd-MM-yy
log4j.appender.R2.layout=org.apache.log4j.PatternLayout
log4j.appender.R2.layout.ConversionPattern=%d{dd/MM/yy kk:mm:ss.SSS} %-5p [%t] %x (%F:%L) - %m%n
In this case, all the logs are printing in the console, but i want only info and error logs in the console.
As far as I know, you can't see INFO, hide WARN, and see ERROR at the same time; this violates the design of the log levels. The levels are defined in this order:
TRACE
DEBUG
INFO
WARN
ERROR
FATAL
However, if you wanted to see only WARN and ERROR in the console, you can do this using the Threshold setting of the appender. Specifically, you just need to add:
log4j.appender.R1.Threshold=WARN
I need to poll the JVM memory stats of my running application on a regular basis. I'm running a service that does this and writes the stats to the root Logger (I don't have much control over Root Logger usage or not).
What I want to do is route just these logging messages to a single appender. This appender should only process logging messages from this one class, and not from any other class. The other appenders shouldn't receive the messages from this one class.
So far I have the log messages only going to this 'memoryStats' appender. However, all the other logging message are also going to that appender, and I need to get rid of them, but I'm not sure how short of listing out every single class which would be a nightmare.
log4j.rootCategory=info, A1, R, MEM
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=[%p] %d{dd MMM yyyy HH;mm:ss,SSS} %t %c{2} (line:%L) - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=logs/ui.log
log4j.appender.R.MaxFileSize=100MB
# Keep backup files
log4j.appender.R.MaxBackupIndex=9
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=[%p] %d{dd MMM yyyy HH;mm:ss,SSS} %t %c{2} (line:%L) - %m%n
log4j.category.foo.bar.services.App.MemoryStats=debug, MEM
log4j.additivity.foo.bar.services.App.MemoryStats=false
log4j.appender.MEM=org.apache.log4j.RollingFileAppender
log4j.appender.MEM.File=logs/memStats.log
log4j.appender.MEM.MaxFileSize=100MB
# Keep backup files
log4j.appender.MEM.MaxBackupIndex=9
log4j.appender.MEM.layout=org.apache.log4j.PatternLayout
log4j.appender.MEM.layout.ConversionPattern=[%p] %d{dd MMM yyyy HH;mm:ss,SSS} %t %c{2} (line:%L) - %m%n
You should remove MEM from log4j.rootCategory.
Change:
log4j.rootCategory=info, A1, R, MEM
to:
log4j.rootCategory=info, A1, R
