For each appender defined on the event source side, you need a matching 'receiver' (defined as a 'plugin' in the configuration file) for Chainsaw to receive events from the matching appender.
See the src/config/log4j-appender-sample.xml and src/config/log4j-receiver-sample.xml
files for example source and sink configurations, respectively.
Configure your app to use the appenders defined in the sample appender config with:
-Dlog4j.configuration=log4j-appender-sample.xml.
Do the same for Chainsaw but with the receiver sample:
-Dlog4j.configuration=log4j-receiver-sample.xml.
ChainsawV2 is also an appender itself and the appender-sample.xml demonstrates how it
can be started automatically (see the LogUI appender section in the
log4j-appender-sample.xml).
Two other receivers are new but sample configurations aren't provided:
JDBCReceiver - works with the existing JDBCAppender
XMLSocketReceiver - works with JDK1.4 socket/XML-formatted events.
The jdbcreceiver example is based on mysql. See the javadoc for more information.
The XMLSocketReceiver requires a 'decoder' to do the work of converting from XML
conforming to a DTD to a loggingevent. Two decoders exist - one for Log4J's dtd and
one for JDK1.4's dtd.
Here are sample configurations for using the JDBCReceiver or XMLSocketReceiver:
<plugin name="JDBCReceiver" class="org.apache.log4j.jdbc.JDBCReceiver">
<param name="refreshMillis" value="5000"/>
<param name="password" value=""/>
<param name="user" value="root"/>
<param name="driver" value="org.gjt.mm.mysql.Driver"/>
<param name="sql" value='select logger as LOGGER, timestamp as TIMESTAMP, level as
LEVEL, thread as THREAD, message as MESSAGE, ndc as NDC, mdc as MDC, class as CLASS,
method as METHOD, file as FILE, line as LINE,
concat("{{log4japp,databaselogs,log4jmachinename,mymachine,log4jid,", COUNTER, "}}")
as PROPERTIES, "" as EXCEPTION from logtable'/>
<param name="URL" value="jdbc:mysql://127.0.0.1/test"/>
</plugin>
<plugin name="XMLSocketReceiver" class="org.apache.log4j.net.XMLSocketReceiver">
<param name="decoder" value="org.apache.log4j.xml.UtilLoggingXMLDecoder"/>
<param name="Port" value="2222"/>
</plugin>
We'll be documenting things more completely in the near future.
Hope this helps,
Scott

Subject: Testing Chainsaw v2
I'd love to help test chainsaw v2 -
Could someone outline a quick howto on getting v2 set
up? I have built it and can run it via the ant build
script in the sandbox, but I can't seem to figure out
how to configure it. I'd like to test it using
receivers, but so far I've only been able to load log
files with it.
How do I set it up to receive events? I'm decently
familiar with v1... but "chainsaw.port" isn't used in
v2.
Thanks a bunch - I look forward to testing v2. My dev
group loves chainsaw v1 and above all else are eager
to get v2 to release stage so we can view/filter on
MDC!!!
Thanks a bunch,
-Scott Heaberlin
