Description: HPOV-NNM-MIB module

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 HPOV-NNM-MIB?

HPOV-NNM-MIB defines general management objects and the enterprise OID root used by HP OpenView Network Node Manager (NNM), including serving as the OpenView Enterprise ID for SNMPv1 traps generated by the NNM application itself. It exposes generic event/alarm-forwarding objects -- source identity, object ID, severity, category, and CMIP-related mapping fields -- used when NNM re-emits or forwards management events as SNMP traps. Its monitoring value is oriented toward software/event status: openViewSeverity and openViewCategory classify the severity/type of an event NNM is reporting, while openViewData carries event detail, giving downstream systems visibility into NNM's own event/alarm processing rather than any specific hardware. It bridges OSI/CMIP-style management events (openViewCmipManagedObjectClass, openViewCmipEventTime) into the SNMP world, showing a dependency on CMIP/OSI management concepts alongside SNMPv1 trap conventions. It is typically deployed wherever HP OpenView NNM acts as a manager-of-managers, forwarding or normalizing events from other management systems to downstream NMS consumers via this MIB's trap format. Network engineers evaluating or troubleshooting this functionality can download the HPOV-NNM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPOV-NNM-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.

Supported Devices

HP OpenView Network Node Manager (NNM) server; forwards events originating from many managed systems

Monitoring Examples

A downstream NMS receiving an SNMPv1 trap under the OpenView enterprise OID would parse openViewSourceId/openViewSourceName and openViewObjectId to identify which NNM-managed object generated the event, and check openViewSeverity/openViewCategory to triage how urgently to respond. For events originating from CMIP/OSI-managed sources, openViewCmipManagedObjectClass and openViewCmipEventTime would be inspected to trace the event back to its original OSI management object and timestamp.

hpOpenView	1.3.6.1.4.1.11.2.17.1			General management information used within the HP OpenView Network Node Manager product. This object identifier also serves as the OpenView Enterprise ID for SNMPv1 Traps.
hpOVNNMTraps	1.3.6.1.4.1.11.2.17.1.0
openViewTrapVars	1.3.6.1.4.1.11.2.17.2
INT openViewSourceId	1.3.6.1.4.1.11.2.17.2.1	INTEGER	accessible-for-notify	The identifier of the software generating the trap/event. This number is used by HP OpenView software when it sends an event to the OpenView event system. It identifies which software component sent the event.
STR openViewSourceName	1.3.6.1.4.1.11.2.17.2.2	OVTextString	accessible-for-notify	The source of the event (may not be the machine upon which the event was generated). This string is used by HP OpenView software when it sends an event. It identifies for which node the event is generated.
STR openViewObjectId	1.3.6.1.4.1.11.2.17.2.3	DisplayString	accessible-for-notify	The OpenView Windows object identifier associated with the source of the trap/event.
OCT openViewData	1.3.6.1.4.1.11.2.17.2.4	OCTET STRING	accessible-for-notify	Any miscellaneous data sent with an OpenView trap/event.
STR openViewSeverity	1.3.6.1.4.1.11.2.17.2.5	OVTextString	accessible-for-notify	The OpenView event severity associated with the trap/event.
STR openViewCategory	1.3.6.1.4.1.11.2.17.2.6	OVTextString	accessible-for-notify	The OpenView event category associated with the trap/event.
STR openViewFilter	1.3.6.1.4.1.11.2.17.2.7	DisplayString	accessible-for-notify	The event filter for an application connecting to the OpenView event system.
STR openViewEntity	1.3.6.1.4.1.11.2.17.2.8	OVTextString	accessible-for-notify	The entity (string name) of an application connecting to the OpenView event system.
STR openViewAddress	1.3.6.1.4.1.11.2.17.2.9	DisplayString	accessible-for-notify	The IP address of the node from where an application is connecting to the OpenView event system.
STR openViewPid	1.3.6.1.4.1.11.2.17.2.10	DisplayString	accessible-for-notify	The process ID of an application connecting to the OpenView event system.
STR openViewCmipManagedObjectClass	1.3.6.1.4.1.11.2.17.2.11	DisplayString	accessible-for-notify	A cmisEventReport managedObjectClass. Only valid when running with the HP OpenView DM product.
STR openViewCmipEventTime	1.3.6.1.4.1.11.2.17.2.12	DisplayString	accessible-for-notify	A cmisEventReport eventTime. Only valid when running with the HP OpenView DM product.
STR openViewCmipEventType	1.3.6.1.4.1.11.2.17.2.13	DisplayString	accessible-for-notify	A cmisEventReport eventType. Only valid when running with the HP OpenView DM product.
STR openViewCmipEventInfo	1.3.6.1.4.1.11.2.17.2.14	DisplayString	accessible-for-notify	A cmisEventReport eventInfo. Only valid when running with the HP OpenView DM product.
STR openViewCmipManagedObjectInstanceId	1.3.6.1.4.1.11.2.17.2.15	DisplayString	accessible-for-notify	A cmisEventReport managedObjectInstance. Only valid when running with the HP OpenView DM product.
OCT openViewEventUUID	1.3.6.1.4.1.11.2.17.2.16	OCTET STRING	accessible-for-notify	An OpenView Event UUID which uniquely identifies an event.
STR openViewEcsCorrelateEvUUID	1.3.6.1.4.1.11.2.17.2.17	DisplayString	accessible-for-notify	If an OpenView event contains this var-bind, it indicates to the Event Correlation System that the event should be correlated with the event whose UUID is the value of this var-bind. If the var-bind is missing or has a zero length value, then no event correlation occurs.
STR openViewEcsNodeImportance	1.3.6.1.4.1.11.2.17.2.18	DisplayString	accessible-for-notify	If an OpenView event contains this var-bind, it indicates to the Event Correlation System the importance of the node from an event correlation perspective. In situations where the ECS system would normally suppress an event, it may choose not to suppress it if the node is very important (e.g. an important server node). The integral value of this MIB object may evolve over time. For now, non-integral values are invalid, a value of zero indicates that the node is a regular node and a non-zero value indicates that the node is an important node.
