Extending Message Transformation

Users can extend Message Transformation to handle additional message sources and write custom rulesets by creating additional configuration files and storing them in the plugins directory under $TRAVERSE_HOME/plugin/messages/. Additional data sources should be defined in configuration files named as nn_src_yyy.xml while additional rulesets should be named nn_rule_yyy.xml where nn is a number and yyy is any freeform text).

As an example, you can add new log files to be monitored and a trap handler listening on port 2162 by creating the following two files in the $TRAVERSE_HOME/plugin/messages/ directory:

00_src_logs.xml

<source type="file" name="mylog">

	<enabled>false</enabled>

	<input>/var/log/mylogs</input>

</source>

<source type="file" name="apacheErrLog">

	<enabled>true</enabled>

	<input>/apache/logs/httpd.error</input>

</source>

00_src_traps.xml

<source type="trap" name="traps2">

	<enabled>true</enabled>

	<port>2162</port>

	<performHostnameLookup>false</performHostnameLookup>

</source>

The format for the rule files is described in the Traverse User Guide. Remember to restart the Message Handler component after editing or creating new files.
