Question

In my existing application “org.apache.log4j” API’s have been used in java code.

Requirement :

I have to log some statement(say xyz) in log file in any case and should not dependent of log levels.For example : if my log level is error then also xyz should print, if my log level is debug then also xyz should print.

I cannot make log statement of xyz is debug because if i do this, other log statements apart from xyz will also start printing.

For this, I believe, I have to add some custom log level.Please help how to do it and how to set its level ordering so that in any case it should print.

Thanks in advance.
Best Regards

What you could do is create a different Logger for those statements (you are not restricted to use classes names when defining a logger)

// Standard logger
private static Logger log = Logger.getLogger(MyClass.class)

// XYZ logger
private static Logger logXYZ = Logger.getLogger("logs.xyz");

You can access the same logger from several class, you just have to pass the same label.

Then, in the configuration file, you can define a different log level for that category, and even output these logs in a different appender (different file, processing, etc.)
