Component Name: Syslog

Issue

Syslog streams are not showing up on the Log Decoder.  They cannot be parsed as they are not seen in the message.

Resolution

The following must be done in order to get the syslog stream to show up on the Log Decoder:

1. Edit the /etc/netwitness/ng/table-map-custom.xml file on the Log Decoder to include the following:

   
   <mapping envisionName="pri.severity" nwName="pri.severity" format="Int32" flags="None" />
   <mapping envisionName="pri.facility" nwName="pri.facility" format="Int32" flags="None" />

2. Edit the /etc/netwitness/ng/index-concentrator-custom.xml file on the Concentrator to include the following:

   
   <key description="Syslog Facility" format="Int32" level="IndexValues" name="pri.facility" valueMax="10000" />
   <key description="Syslog Severity" format="Int32" level="IndexValues" name="pri.severity" valueMax="10000" />

3. Restart the Log Collector, Log Decoder and Concentrator services in order to reflect the changes.  The values should then begin to show up in the investigation module within Security Analytics.
