Gary Gregory commented on LOG4J2-1597: -------------------------------------- WIP in branch {{LOG4J2-1597}}. > Add a ScriptSelector Appender to create an Appender specified by a Script > ------------------------------------------------------------------------- > > Key: LOG4J2-1597 > URL: https://issues.apache.org/jira/browse/LOG4J2-1597 > Project: Log4j 2 > Issue Type: New Feature > Components: Appenders > Reporter: Gary Gregory > Assignee: Gary Gregory > > The use case is to create an OS-based dynamic configuration file. > The script determines which appender to use (once), and instantiates that > appender (once). There is no need for one appender to delegate to another > appender. > This feature helps you build your configuration dynamically, all from the > configuration file, to determine which appenders to configure. This is > different from using a RoutingAppender which creates a level of indirection > and decides what to do for each log event _at runtime_. > You can use multiple ScriptSelector Appenders if needed. > For example: > {code:xml} > <Configuration status="WARN" name="RoutingTest"> > <Appenders> > <ScriptSelector name="InitAppender"> > <Script language="JavaScript"><![CDATA[ > "OSNameFoo".search("Foo") > -1 ? "List2" : "List1";]]> > </Script> > <AppenderSet> > <List name="List1" /> > <List name="List2" /> > </AppenderSet> > </ScriptSelector> > </Appenders> > <Loggers> > <Root level="error"> > <AppenderRef ref="InitAppender" /> > </Root> > </Loggers> > </Configuration> > {code} > The new plugins are ScriptSelector (an Appender that builds a different > ScriptSelector) and AppenderSet, a plugin with deferChildren set to true. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: log4j-dev-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-dev-h...@logging.apache.org
