|
|
|prod| supports :abbr:`SNMP (Simple Network Management Protocol)` traps. Traps
|
|
send unsolicited information to monitoring software when significant events
|
|
occur.
|
|
|
|
The following traps are defined.
|
|
|
|
.. _traps-ul-p1j-tvn-c5:
|
|
|
|
- wrsAlarmCritical
|
|
|
|
- wrsAlarmMajor
|
|
|
|
- wrsAlarmMinor
|
|
|
|
- wrsAlarmWarning
|
|
|
|
- wrsAlarmMessage
|
|
|
|
- wrsAlarmClear
|
|
|
|
- wrsAlarmHierarchicalClear
|
|
|
|
|prod| alarms are mapped into one of the above traps based on severity, and
|
|
customer logs are mapped into the 'Message' trap.
|
|
|
|
.. note::
|
|
|prod| uses Wind River Systems (**wrs**) Enterprise Registration and Alarm
|
|
MIBs. See :ref:`SNMP Overview <snmp-overview>` for details.
|
|
|
|
For Critical, Major, Minor, Warning, and Message traps, all variables in the
|
|
active alarm table are included as varbinds \(variable bindings\), where each
|
|
varbind is a pair of fields consisting of an object identifier and a value
|
|
for the object.
|
|
|
|
For the Clear trap, **varbinds** include only the following variables:
|
|
|
|
.. _traps-ul-uks-byn-nkb:
|
|
|
|
- wrsAlarmActiveAlarmID
|
|
|
|
- wrsAlarmActiveEntityInstanceID
|
|
|
|
- wrsAlarmActiveDateAndTime
|
|
|
|
- wrsAlarmActiveReasonText
|
|
|
|
For the HierarchicalClear trap, **varbinds** include only the following
|
|
variables:
|
|
|
|
.. _traps-ul-isn-fyn-nkb:
|
|
|
|
- wrsAlarmActiveEntityInstanceID
|
|
|
|
- wrsAlarmActiveDateAndTime
|
|
|
|
- wrsAlarmActiveReasonText
|
|
|
|
For all alarms, the Notification Type is based on the severity of the trap or
|
|
alarm. This is done to facilitate the interaction with most SNMP trap viewers
|
|
which use the Notification Type to drive the coloring of traps, that is, red
|
|
for critical, yellow for minor, and so on.
