Specifying filtering operations for resychronization
During resynchronization, the probe can perform various filtering operations, the details of which are defined in the filter file specified by the ResyncFilterFile property.
Simple filters
Simple filters use the following syntax:
<v11:filter>
<v11:attributeNameList>
<v13:attributeName>POSSIBLE_VALUE</v13:attributeName>
</v11:attributeNameList>
</v11:filter>
Where attributeName
is
one of the event attributes listed in the table below, and POSSIBLE_VALUE
is
one of the values listed for that attribute.
The following
example code shows how to use the filter file to select for resynchronization
all those events that have a perceivedSeverity
of MINOR
:
<v11:filter>
<v11:perceivedSeverityList>
<v13:perceivedSeverity>MINOR</v13:perceivedSeverity>
</v11:perceivedSeverityList>
</v11:filter>
More complex filters
Complex filters use the following syntax:
<v11:filter>
<v11:source>AlarmSourceType</v11:source>
<v11:scope>
<v12:name>
<v12:rdn>
<v12:type></v12:type>
<v12:value></v12:value>
</v12:rdn>
</v12:name>
</v11:scope>
<v11:attributeNameList>
<v13:attributeName>POSSIBLE_VALUE</v13:attributeName>
<v13:attributeName>POSSIBLE_VALUE</v13:attributeName>
</v11:attributeNameList>
<v11:probableCauseList>
<v14:prc extension="?" qualifier="?">
<v14:ru>false</v14:ru>
<v14:contra>false</v14:contra>
<v14:probableCause>PROBABLE_CAUSE</v14:probableCause>
</v14:prc>
</v11:probableCauseList>
<v11:acknowledgeIndication>ACKNOWLEDGEMENT_STATUS</v11:acknowledgeIndication>
</v11:filter>
The following example code shows how to use the filter file to select for resynchronization only
those alarms generated by MTOSI server, that have a perceivedSeverity
of either
WARNING
, or MINOR
, and whose probable cause is transmission
failure.
<v11:filter>
<v11:source>INTERNAL</v11:source>
<v11:scope>
<v12:name>
<v12:rdn>
<v12:type>MD</v12:type>
<v12:value><Object Name of Network Element></v12:value>
</v12:rdn>
</v12:name>
</v11:scope>
<v11:perceivedSeverityList>
<v13:perceivedSeverity>WARNING</v13:perceivedSeverity>
<v13:perceivedSeverity>MINOR</v13:perceivedSeverity>
</v11:perceivedSeverityList>
<v11:probableCauseList>
<v14:prc extension="?" qualifier="?">
<v14:ru>false</v14:ru>
<v14:contra>false</v14:contra>
<v14:probableCause>TX_FAIL</v14:probableCause>
</v14:prc>
</v11:probableCauseList>
<v11:acknowledgeIndication>?</v11:AI_EVENT_UNACKNOWLEDGED>
</v11:filter>

The following table shows a list of attributes that you can use within complex filter files, and their corresponding possible values.
Name | Type | Description | Example |
---|---|---|---|
source |
AlarmSourceType |
Use this attribute to filter alarms based on alarm source type. The attribute can be set to one of the following values:
Note: When query internal alarm from a specific target system, source parameter should set to
INTERNAL . |
|
scope |
NamingAttribute ListType |
Use this attribute to filter the alarms based
on specific managed elements. If no managed element is specified,
alarms from all managed elements are selected.
Note: The specified
value must be the MTOSI object name of a network element.
When an network element name is specified, it indicates the equipment from which alarms are queried. |
|
perceived SeverityList |
PerceivedSeverity ListType |
Use this attribute to filter the alarms based on a specified level of severity. This can be set to one of the following values:
|
|
probableCause List |
ProbableCause List Type |
Use this attribute to filter the alarms based on a list of probable causes. If no probable causes are specified, all alarms will be selected for resynchronization. Note: You
can specify any of the standard MTOSI probable cause descriptions.
For details, see the TM Forum MTOSI web site.

ru |
ProbableCause List Type |
The following sub-attribute is defined for each probable cause:
false: The alarm is associated with a local network resource. true: The alarm is associated with a remote network resource. |
|
contra |
ProbableCause List Type |
The following sub-attribute is defined for each probable cause:
false: The alarm is detected on the signal related to the sink atomic function. true: The alarm is detected on the signal related to the source atomic function. |
|
acknowledge Indication |
Acknowledge IndicationType |
Use this attribute to filter the alarms based on the acknowledgement status. The attribute can be set to one of the following values:
