Description: DMTF DMI-to-SNMP mapping agent MIB providing SNMP access to DMI component, group, and MIF metadata on managed systems

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 DMTFDMI?

DMTFDMI is the core DMTF DMI-to-SNMP mapping agent MIB, exposing the metadata of the Desktop Management Interface (DMI) Service Layer itself rather than data from any one hardware subsystem. It provides tables describing every DMI component, group, and MIF class known to the agent, including dmiClassTable entries that record each class's OID, name, version, key count, and description length. In monitoring terms this MIB is used less for hardware telemetry and more for software/agent status: it lets a management station enumerate what DMI instrumentation and MIF classes are currently registered and version-tracked on a managed system, useful for verifying the DMI agent is running correctly and that expected instrumentation classes are present. Because it is the mapping layer itself, virtually every other DMTF-translated MIB (such as DMTF-LAN-ADAPTER-MIB and DMTF-MOBILE-MIB) depends on the DMI service layer this MIB describes. It is deployed on DMI-instrumented systems, primarily legacy PCs, servers, and workstations from the DMI era, wherever an SNMP-to-DMI mapping agent is running, and it remains a useful DMTFDMI reference for engineers maintaining legacy DMI-instrumented hardware.

IPNetwork Monitor allows you to monitor SNMP objects defined in DMTFDMI. 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 admin can poll dmiClassTable/dmiClassEntry (indexed by dmiClassIndex) to read dmiClassString, dmiClassName, dmiClassVersion, and dmiClassOID, confirming which MIF class definitions and versions the DMI Service Layer currently has registered, and cross-check dmiAttributeTable for the attributes each class exposes. A missing expected class, or a class version that unexpectedly changed after a software update, would indicate an inconsistency in the DMI instrumentation on that host. This is fundamentally a metadata/inventory MIB rather than one exposing live performance counters.

What Can Be Monitored

registered DMI class/MIF inventory
DMI class version
DMI class OID and key count

For example, a mapping agent that supports Event and Request/Response mapping, including Dynamic OID Generation, but does not support row addition/deletion nor remote proxy returns the value 0x13.
dmiNotifications	1.3.6.1.4.1.412.1.2
dmiIndications	1.3.6.1.4.1.412.1.2.0
NTF dmiEventIndication	1.3.6.1.4.1.412.1.2.0.0.1			A DMI Event associated with a group within a DMI component has occurred. Normally, DMI Events are translated into event specific SNMP notifications instead of this generic notification. However, this generic notification is defined for cases when mapping the DMI event to a specific SNMP trap is not possible (e.g., the DMI Class to SNMP OID mapping is not defined).
NTF dmiComponentAddedIndication	1.3.6.1.4.1.412.1.2.0.0.2			A new component has been installed into the DMI Service Layer.
NTF dmiComponentDeletedIndication	1.3.6.1.4.1.412.1.2.0.0.3			An installed component has been uninstalled from the DMI Service Layer.
NTF dmiLanguageAddedIndication	1.3.6.1.4.1.412.1.2.0.0.4			A new language binding has been added to a component in the DMI Service Layer.
NTF dmiLanguageDeletedIndication	1.3.6.1.4.1.412.1.2.0.0.5			An existing language binding has been removed from a component in the DMI Service Layer.
NTF dmiGroupAddedIndication	1.3.6.1.4.1.412.1.2.0.0.6			A new group has been added to a component in the DMI Service Layer.

I32 dmiEventType	1.3.6.1.4.1.412.1.2.1.1	Integer32	read-only	Event-specific information that identifies the type of event within the DMI Event Generation group. Normally, this information is conveyed in the resulting SNMP Notification OID derived from the DMI Event to SNMP Trap mapping procedure. This object is not included in event specific traps. However, this object is defined for use within the generic dmiEventIndication trap, when mapping the DMI event to a specific SNMP trap is not possible (e.g., the DMI Class to SNMP OID mapping is not defined).
INT dmiEventSeverity	1.3.6.1.4.1.412.1.2.1.2	INTEGER	read-only	The severity of this event.
I32 dmiEventStateKey	1.3.6.1.4.1.412.1.2.1.4	Integer32	read-only	The index into the Event State group for the component generating this event, provided the event is state-based. The value -1 indicates the event is not state-based.
STR dmiEventAssociatedGroup	1.3.6.1.4.1.412.1.2.1.5	DmiString	read-only	The class string of the DMI group associated with this event.
I32 dmiEventSystem	1.3.6.1.4.1.412.1.2.1.6	Integer32	read-only	Event-specific information that identifies the functional system of the component that caused the event. Normally, SNMP Traps mapped from a DMI Event contain an event-specific definition of this attribute. This object is not included in event specific traps. However, this object is defined for use within the generic dmiEventIndication trap, when mapping the DMI event to a specific SNMP trap is not possible (e.g., the DMI Class to SNMP OID mapping is not defined).
I32 dmiEventSubSystem	1.3.6.1.4.1.412.1.2.1.7	Integer32	read-only	Event-specific information that identifies the functional sub-system of the component that caused the event. Normally, SNMP Traps mapped from a DMI Event contain an event-specific definition of this attribute. This object is not included in event specific traps. However, this object is defined for use within the generic dmiEventIndication trap, when mapping the DMI event to a specific SNMP trap is not possible (e.g., the DMI Class to SNMP OID mapping is not defined).
I32 dmiEventSolution	1.3.6.1.4.1.412.1.2.1.8	Integer32	read-only	Event-specific information that describes the solution to the problem that caused the event. Typically, SNMP Traps mapped from a DMI Event contain an event-specific definition of this attribute. This object is not included in event specific traps. However, this object is defined for use within the generic dmiEventIndication trap, when mapping the DMI event to a specific SNMP trap is not possible (e.g., the DMI Class to SNMP OID mapping is not defined).
STR dmiEventVendorMsg	1.3.6.1.4.1.412.1.2.1.10	DmiString	read-only	Vendor specific message related to the event. This data may contain any displayable string (ISO 8859-1).
OCT dmiEventVendorData	1.3.6.1.4.1.412.1.2.1.11	OCTET STRING	read-only	Vendor specific data related to the event. This data may contain any arbitrary string of octets.
OCT dmiEventDateTime	1.3.6.1.4.1.412.1.2.1.12	OCTET STRING	read-only	The timestamp attached to an event indication by the DMI Service Layer.
STR dmiEventClassString	1.3.6.1.4.1.412.1.2.1.13	DmiString	read-only	The Event Group class string used, along with the event type, to uniquely identify the DMI Event when translated into the general dmiEventIndication trap format.
ADR dmiEventSource	1.3.6.1.4.1.412.1.2.1.14	DmiTDAddress	read-only	The transport address that identifies the originator of the DMI Event or Indication. The event may be forwarded by other Service Layers acting as intermediaries for the originator of the event, or the event may have originated on a system other than the local mapping agent. This variable binding is only included in DMI Events and Indications if the original source is a system other than where the SNMP/DMI mapping agent is operating. If the transport selector (e.g., UDP port or IPX socket) of an SNMP mapping agent running on the specified system is not known, a zero (0) value is to indicate that only the network address portion is known. Otherwise, the transport selector value may be used by management applications to send SNMP requests directly to the specified system.
dmiMIBConformance	1.3.6.1.4.1.412.1.3
dmiMIBCompliance	1.3.6.1.4.1.412.1.3.1
