Adding Categories Granularly

Last updated 4 months ago

You can also add categories with very granular information using the category() method. This method will allow you to add a category definition with a range of severity levels and even a list of which appenders to respond to.

public void category(
string name,
[numeric levelMin='0',]
[numeric levelMax='4',]
[string appenders='*']
)

Parameters:

Name

Description

name

A unique name for the appender to register. Only unique names can be registered per instance.

levelMin

The default min log level for this category. (OPTIONAL. Defaults to 0 [FATAL].)

levelMax

The max default log level for this category. (OPTIONAL. Defaults to 4 [DEBUG].)

appenders

A list of appender names to configure this category with else it will use all the appenders in the root logger. You can also use * to add all registered apenders. (OPTIONAL)

Example

//log all email service messages to the MyLogFileAppender and the Console.
config.category( name="org.model.EmailService", appenders="MyLogFileAppender,Console" );
