How do we turn on the Snmp4j logging for trap data in SOI connector for SNMP 2.0 which is built on the IFW framework?



Component: SOIMGR


1. Navigate to the SOI\resources folder on SNMP connector machine.

2. Open the log4j.xml file and add the following sections to the file (logger definitions section). 

<logger name="org.snmp4j">
  <level value="DEBUG" />
  <appender-ref ref="SNMP4J" />

<appender name="SNMP4J" class="org.apache.log4j.RollingFileAppender"> 
<param name="File" value="&logDir;/snmp4j.log"/> 
<param name="Append" value="true"/> 
<param name="MaxFileSize" value="20MB"/> 
<param name="MaxBackupIndex" value="10"/> 
<layout class="org.apache.log4j.PatternLayout"> 
<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss,SSS} %p [%t] %c{2} - %m. %n"/> 

3) Restart CA SAM Integration Services on this SNMP Connector.

4) Then you will see a snmp4j.log file created under SOI\log directory.

Additional Information

Note that there are steps in subsequent 4.2 patches that will create a log4j_IFW.xml as well as log4j.xml

In the circumstance where you find both log4j.xml and log4j_IFW.xml on the machine, the updates should be made in the log4j_IFW.xml file


It is possible to set extra debug of the logging by changing the debug flag to true in the XML file

<log4j:configuration debug="true" xmlns:log4j="http://jakarta.apache.org/log4j/">

This will write information about the configured log appenders in the jsw/logs/SAM-IntegrationServices_wrapper.log. Here it is possible to check if the SNMP appender is listed.
