Adding an SNMP Appender to the log4j.xml File

Add an SNMP appender to the

Data Integration Hub

server or Operation Console copies of the log4j.xml file to customize the output destination for log messages.

Back up the log4j.xml file that you want to edit from one of the following locations:

Data Integration Hub

server:

DIH

InstallationDir>/conf

Operation Console:

DIH

InstallationDir>/

DataIntegrationHub

/tomcat/shared/classes

Open the file in a text editor and search for the following text:

SNMP_TRAP is a sample appender

To edit the sample appender with the actual values of your appender, remove the comment indicators from the SNMP_TRAP appender and edit the appender parameters and values based on your requirements.

You can also add an appender below the sample appender instead of editing the sample appender.

To set the formatting of the log messages, edit the layout element.

The following example shows the layout element of the sample appender:

<layout class="org.apache.log4j.PatternLayout">
   <param name="ConversionPattern" value="%d{ISO8601} %-5p [%c] {%t} %m%n"/>
</layout>

For information about the layout pattern options, see the description on the Apache Website: http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html

To activate the appender, search for the following text:

<root>

Add the appender name to the appender list.

The following example shows the appender list after you add the appender name:

<root>
   <priority value="INFO"/>
   <appender-ref ref="BROKER-LOG"/>
   <appender-ref ref="CONSOLE"/>
   <appender-ref ref="SNMP_TRAP"/>
</root>

Save the log4j.xml file.

After you add the SNMP appender, configure your SNMP manager to listen for the log messages.
