Description: Tracks event log history and active alarm list for Net Insight Nimbra media transport platforms.

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-EVT-MIB?

NETI-EVT-MIB is a Net Insight vendor MIB providing a generic event-and-alarm logging mechanism for Nimbra media transport platform devices. It exposes an event history table and an active alarm list, along with SNMP notifications that fire whenever alarms change state or other tables in companion Net Insight MIBs are modified. It is centrally used for monitoring device fault and software status: each event carries a severity, cause, type, and free-text description, letting operators detect hardware faults, configuration changes, and abnormal conditions as they occur rather than only through periodic polling. The MIB explicitly depends on other Net Insight MIBs, since it acts as a generic notification-of-change mechanism that those modules reuse to report their own table changes. It is deployed as the central event/alarm subsystem across Nimbra media transport node deployments in broadcast and telecom networks. Engineers can download the NETI-EVT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETI-EVT-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

An NMS would poll nevtSequenceCounter and nevtLastChangedTime to detect whether new entries have been added to nevtEventTable since the last poll, then walk nevtEventEntry rows to read nevtEventSeverity, nevtEventCause, and nevtEventText for each new event. A notification receiver that missed a trap can use nevtEventIndex to fetch the specific missed event object from the table rather than losing the alarm entirely. A string of events with nevtEventAlarmType indicating an alarm-set condition combined with high nevtEventSeverity would flag an active hardware or link problem needing attention.

netiGeneric	1.3.6.1.4.1.2928.2
nevtMIB	1.3.6.1.4.1.2928.2.1			MIB containing event and alarm information. The MIB contains tables for events and alarms, and defined notifications for events and alarms. nevtEventTable. Table with the last number of events. 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. nevtAlarmTable. Table with all active alarms, and the last historic alarms. The alarm table holds all active alarms, and possibly also a number of the last cleared alarms. nevtActiveAlarmTable. Table will all active (non-clear) alarms. The active alarm table holds only the active alarms.

U32 nevtSequenceCounter	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 whether 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
