A severity mapping file is an ASCII file that is used to determine the actual severity of an alarm instance to generate when the alarm configuration specifies an alarm severity of Conditional.


The Conditional alarm severity allows you to assign the alarm severity based on the value of a variable binding sent with the trap that triggered the event. Moreover, it also allows you to select the set of mappings between values and alarm severity levels to use when determining the actual alarm severity.


It is the severity mapping file that defines the mappings between possible variable binding values and SPECTRUM alarm severity levels.


You can create severity mapping files and customize those that are provided by default with SPECTRUM.


An example is the $SPECROOT/SS/CsVendor/OmniPCX/SeverityMaps/severity file. The following is the contents of this file:


2 3
3 2
4 1
5 1
6 C


In the above example, if the value of the varbind is 2, then the Alarm Severity will be 3 (Critical). If the value of the varbind is 3, then the Alarm Severity will be 2 (Major). If the value of the varbind is 4 or 5, then the Alarm Severity will be 1 (Minor). If the value of the varbind is 6, then an existing alarm will be cleared (C).


An example of how the Severity Map is used in the EventDisp file is located in the $SPECROOT/SS/CsVendor/OmniPCX directory:


0x04ca0182 E 20 A { v 3 OmniPCX.severity },0x04ca0182


In the above example, the value of varbind 3 is checked against the OmniPCX.severity Severity Map file to deteremine the Alarm Severity.
