9.5. Defining the Alarm Filter Clues
Alarm Filter Clues describe specific criteria that the VIP will use to
determine if each record should be counted as a match. Up to sixteen clues
can be defined for each Alarm Filter.
When the Alarm Filter is assigned to an input port, all data received by that
port will be monitored. The VIP will scan each record to determine if it
matches any of the defined Alarm Clues. Records that match Alarm Clues
are flagged and counted. When data is released to the polling device, alarm
records can be sorted according to the name of the clue that was matched.
When defining Clues, the following factors should be considered:
Clue Name: Names should describe the type of call the clue
will monitor.
Threshold Count: The number of times this type of call must occur
in order to generate an alarm.
Match Parameters: The qualities that identify a suspect call. For
example, long distance calls are easily recognized because they begin
with the number one. Call characteristics are expressed in the form of
an equation, which includes the following elements:
Variable(s): One or more variables from the Alarm Filter Format
or one or more Real-Time variables. Variables determine which
field(s) will be monitored. For example, the variable may represent
the field for the number dialed.
Operator(s): One or more logical/relational operators, such as >, <,
and = (see Section 9.6).
Parameter(s): A description of the characteristics that determine
whether each record is counted as a match. For example, calls to a
specific phone number, or calls made after a specific time.
Action Parameters: A Series of parameters that determine how
the VIP will react when the counter for this clue reaches the defined
threshold. The VIP can send an SNMP Trap, call a modem or pager,
contact the user via the Console Port, open or close the optional Output
Contacts or send an Email or Text Message. For more information on
Alarm Actions, please refer to Section 13.
Note: The Output Contact option is not available on
NLJ-VIP units.
