Rhino 3.2 :: Rhino Administration and Deployment Guide

A Rhino management sub task for creating a log appender.

Ant Parameters
Attribute	Type	Description	Required
appendername	String	Name of the appender to create. This name must be unique.	Yes.
pluginname	String	The Log4J plugin for this appender	Yes.
properties	String	A comma separated list of configuration properties for the appender. Each property is a key=value pair. Use this or a nested propertyset.	No.
failonerror	boolean	Flag to control failure behaviour. If 'true', the sub task will throw a `BuildException` when an error is encountered. If 'false', the sub task will throw a `NonFatalBuildException` instead of a `BuildException` under specific circumstances. See below for conditions (if any) which will cause a `NonFatalBuildException`.	No. Default value is taken from the Rhino management parent task.

Nested elements
Element	Description	Required
propertyset	Configuration properties for this appender. Alternative to the properties attribute.	No.
filter	A filter to select events that will be reported by this appender.	No.
layout	The layout to use to format log events. If no layout is supplied the default pattern layout of "%m%n" will be used.	No.
component	Additional components such as loggerFields for SyslogAppender, KeyValuePairs, etc. Multiple components may be specified. See `CreateGenericComponentTask`.	No

NonFatalBuildException throw conditions

This task will throw a NonFatalBuildException if the appender cannot be created, eg. an appender with the same name already exists.

To use this task provide the configuration of the appender as attributes and subelements. For example, to replicate the Log4J Cassandra appender example, first configure Cassandra with a keyspace test containing a table logs, add the Cassandra client jar and log4j-nosql-2.8.2.jar to rhino/lib/logging-plugins before starting Rhino, then create an Ant target containing the below slee-management block.

  <Appenders>
    <Cassandra name="Cassandra" clusterName="Test Cluster" keyspace="test" table="logs" bufferSize="10" batched="true">
      <SocketAddress host="localhost" port="9042"/>

      <ColumnMapping name="timeid" literal="now()"/>

    <Root level="ERROR"/>
  </Loggers>
