Email log4j errors to different groups

Am using log4j for my error reporting. Ive set my log 4j to also append errors to emails. However i need it to send emails to separate groups depending on the level of the message. For example

      info messages go to management- john@management.com, peter@management.com, simon@management.com                   
       debug messages go to programmers - paul@programmer.com, matt@programmer.com
       warn messages go to administrator - admin@admin.com

In such a fashion, is it possible? And has anyone implemented said procedure (a sample properties file would be app开发者_运维百科reciated)

Is should be easy to configure something like this using the SMTPAppender from log4j. But be aware, that emailing logs takes quite a bit of load, especially if you consider mailing DEBUG reports to developers.

You can use a log4j Filter to do this (http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/spi/Filter.html)

The example below writes messages to different files according to the log level. This can be easily adapted to an SMTPAppender instead of a FileAppender.
