Subscribing to the 5620-SAM-topic-xml-filtered topic

To subscribe to the 5620-SAM-topic-xml-filtered topic, set the JmsTopic property to 5620-SAM-topic-xml-filtered. The probe will receive events of type EventVessel and XMLFilterChange. You can limit the messages that the SAM sever sends to the probe by specifying an XML filter using the AdvancedFilterConfigFile property.

You can dynamically modify the XML message filter when the probe is running by issuing a registerNotification command from the CLI, or you can specify an alternative XML filter by issuing a registerNotificationFile command. For details of these commands, see Command line interface.

The default AdvancedFilterConfigFile contains the following XML code:

<filter-Set>
	<filter>
   <and>
    <equal class="jmsEvent" name="MTOSI_NTType" value="NT_ALARM" />
     <not>
       <equal class="jmsEvent" name="MTOSI_NTType" 
            value="NT_ATTRIBUTE_VALUE_CHANGE" />
            </not>
    </and>
	</filter>
</filter-Set>
<extraTags>
	<tag name="ALA_category" />
	<tag name="eventName" />
	<tag name="MTOSI_osTime" />
	<tag name="MTOSI_objectType" />
	<tag name="MTOSI_perceivedSeverity" eventName="ObjectCreation" />
	<tag name="ALA_alarmType" eventName="ObjectCreation" />
	<tag name="ALA_clientId"  />
</extraTags>

When the probe subscribes to the 5620-SAM-topic-xml-filtered topic, by default, the event vessel does not contain the JMS header properties of the individual events. You must use the AdvancedFilterConfigFile property to specify the JMS header properties (for example, MTOSI_osTime, eventName, and so on).
