What is a Severity-based trap?

Applies to

ONTAP 9

Answer

Severity-based trap is a trap type that is issued in response to the severity of an EMS event that has raised. 

Note:

• EMS has a trap type configured for each event. 
• ONTAP has three trap types: Standard, Severity-based, and Built-in. 
  • Standard: Defined in the RFCs
  • Built-in:  NetApp Enterprise traps specific to events
  • Severity-based: Other than above
• Severity-based traps are fired when an event matching the event filter setting occurs. 
• The ONTAP system-defined filter default-trap-events has the following filter

Filter Name Rule     Rule      Message Name           SNMP Trap Type  Severity
            Position Type
----------- -------- --------- ---------------------- --------------- --------
default-trap-events
            1        include   *                      *               EMERGENCY, ALERT
            2        include   callhome.*             *               ERROR
            3        include   *                      Standard, Built-in
                                                                      *
            4        exclude   *                      *               *

• This filter means:

1. Exclude all events
2. Include all EMERGENCY, ALERT events
3. Include all ERROR events which start with callhome.
4. include all  Standard, Built-in events

• When a callhome.* event of ERROR severity, or an EMERGENCY or ALERT event is raised and the trap type is neither Standard nor Built-in,  EMS will notify by Severity-based trap according to the severity of each event raised.
