[jira] [Commented] (SLING-3069) Allow attaching an Appender to a Logger without changing its existing Log level

["Carsten Ziegeler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-3069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13768153#comment-13768153 ] 

Carsten Ziegeler commented on SLING-3069:
-----------------------------------------

I suggest to create three different service registration properties:
- logger name
- log level (optional) - defaults to empty value
- additive (optional) - defaults to true

If no log level is set, the log level of the logger is not changed at all

> Commons Log now supports attaching Appenders as OSGi services. Current implementation while trying to attach appender also modifies the Log level to INFO if none specified. It should be possible to attach an appender without modifying the existing log level
