8.5. Defining the Alarm Filter Clues


Alarm Filter Clues describe specific criteria that NetLink 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. NetLink 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 8.6).

•          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 NetLink will react when the counter for this clue reaches the defined threshold. NetLink can send an SNMP Trap, call a modem or pager, contact the user via the Console Port, or open or close the optional Output Contacts. For more information on Alarm Actions, please refer to Section 12.

Figure 8.3: Alarm Filter Format Definition Screen

1                     The format definition menu will show three sample records, followed by the previous format definition. Although the structure will differ for each PBX, records will look something like those shown in Figure 8.4.

2                     Define the Alarm Filter Format: The prompt at the bottom of the menu is used to define the Alarm Filter.


a) Press the dash key to indicate a field position you do not need to monitor. In Figure 8.4, dashes have been entered in the first four fields of the record.

b) When you reach a field that you need to monitor, key in the variable (any uppercase letter) that will be assigned to that position. For example, to assign "A" to the first seven digits of the number dialed, enter seven A's as shown in Figure 8.4. The same variable is repeated for each position in the field.

c) When you reach the last position you need to monitor, press [Enter]. NetLink will save the Alarm Filter Format and return to the Alarm Filter Configuration menu.


In order to assist the user during format definition, several data records and the previous format are displayed in the following order:
