Description: Defines event notification objects and alarm severity levels for Net Insight Nimbra fault management.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is NETI-EVENT-MIB?

NETI-EVENT-MIB is a Net Insight MIB module for the Nimbra DTM (Dynamic synchronous Transfer Mode) transport network family, providing a generic event and alarm reporting mechanism shared across Net Insight nodes. It exposes an event table logging discrete occurrences sent as SNMP notifications and an alarm table holding currently active alarm conditions, along with alarm type, severity, and cause codes. It is squarely a fault-management MIB: eventSeverity, eventAlarmType, and eventCause let an administrator monitor active fault conditions on the node, while eventSequenceCounter and eventLogLastChangedTime let a management station detect and recover any notifications it missed, making this the general health/status reporting mechanism for the whole Nimbra platform. It is explicitly designed as a shared notification framework that other Net Insight MIBs (such as NETI-ITS-MIB) depend on to report their own state changes as events and alarms. It is deployed in broadcast and telecom transport networks running Net Insight Nimbra DTM equipment for centralized fault and alarm monitoring, where NETI-EVENT-MIB SNMP monitoring provides the shared event/alarm backbone across the Nimbra platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETI-EVENT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

eventTable/eventEntry, indexed by eventIndex, holds eventObject, eventObjectName, eventType, eventSeverity, eventCause, and eventText for each logged occurrence, while eventSequenceCounter and eventLogLastChangedTime let an NMS detect gaps if it missed one or more SNMP trap notifications. An administrator scanning the alarm table for eventSeverity at a critical level tied to a specific eventObjectName can immediately identify which underlying Nimbra service or interface has degraded. Correlating eventCause across multiple entries for the same object also helps distinguish a transient blip from a persistent fault.

What Can Be Monitored

OIDs

OID symbolic	OID numeric	Type	Access	Description
netiEventMIB	1.3.6.1.4.1.2928.2.1			Mib containing event and alarm information. The mib implements two tables and some notifications. One table is holding events and one is holding alarms. The event table contains the events that are sent as SNMP notifications. These events indicate change of alarms, or change in other tables defined in other mibs, that uses the mechanism in this mib to notify a table change. If a notification receiver misses notifications, it can retrieve the lost notifications from this table. The alarm table holds all active alarms, and possibly also a number of the last cleared alarms. The active alarm table holds only the active alarms.
eventObjects	1.3.6.1.4.1.2928.2.1.1
U32 eventSequenceCounter	1.3.6.1.4.1.2928.2.1.1.1	Unsigned32	read-only	The index of the latest sent event defined as notifications in this mib. By examine his object, the notification receiver can determine wheter it has missed any notifications. The counter resets to zero at cold start, indicating that no events has been sent, and that the event table is empty. The counter will wrap and restart at value '1' when it passes its maximum value
DAT eventLogLastChangedTime	1.3.6.1.4.1.2928.2.1.1.2	DateAndTime	read-only	The time when an event was last changed, and a notification was sent.
eventTable	1.3.6.1.4.1.2928.2.1.1.3		not-accessible	Table containing the most recent events. The maximum size of the table depends on the implementation
eventEntry	1.3.6.1.4.1.2928.2.1.1.3.1		not-accessible	One entry in the table holds one event. Events are either created by the agent when a conceptual row has been changed in a table defined in another mib, or when an alarm status is changed in the alarm table defined in this mib.
U32 eventIndex	1.3.6.1.4.1.2928.2.1.1.3.1.1	Unsigned32	read-only	Arbitrary index for an entry in the event table. The eventIndex follows the eventSequenceCounter as such that the eventSequenceCounter refers to the last event in the table

The value is the name of the instance of the first accessible columnar object in the conceptual row. For example, dtmIfIndex.3 would point to the 3rd row in the dtmIfTable. If the object is unavailable, the value is { 0 0 }.
STR eventObjectName	1.3.6.1.4.1.2928.2.1.1.3.1.3	DisplayString	read-only	A text describing the object that caused the event in a for humans more readable form. If not set then this object contains a zero-length string.
