A table of Notification log entries.
It is an implementation-specific matter whether entries in this table are preserved across initializations of the management system. In general one would expect that they are not.
Note that keeping entries across initializations of the management system leads to some confusion with counters and TimeStamps, since both of those are based on sysUpTime, which resets on management initialization. In this situation, counters apply only after the reset and nlmLogTime for entries made before the reset MUST be set to 0.
The indexes of the table are nlmLogName, nlmLogIndex.

Implemented Specifications |
---|---|---|---|---|---|
1.3.6.1.2.1.92.1.3.1.1.1 |
nlmLogIndex |
Unsigned32{(1,4294967295)} |
not-accessible |
A monotonically increasing integer for the sole purpose of indexing entries within the named log. When it reaches the maximum value, an extremely unlikely event, the agent wraps the value back to 1. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.2 |
nlmLogTime |
TimeTicks |
read-only |
The value of sysUpTime when the entry was placed in the log. If the entry occurred before the most recent management system initialization this object value MUST be set to zero. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.3 |
nlmLogDateAndTime |
OCTET STRING{(8,8),(11,11)} |
read-only |
The local date and time when the entry was logged, instantiated only by systems that have date and time capability. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.4 |
nlmLogEngineID |
OCTET STRING{(5,32)} |
read-only |
The identification of the SNMP engine at which the Notification originated.
If the log can contain Notifications from only one engine or the Trap is in SNMPv1 format, this object is a zero-length string. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.5 |
nlmLogEngineTAddress |
OCTET STRING{(1,255)} |
read-only |
The transport service address of the SNMP engine from which the Notification was received, formatted according to the corresponding value of nlmLogEngineTDomain. This is used to identify the source of an SNMPv1 trap, since an nlmLogEngineId cannot be extracted from the SNMPv1 trap pdu.
This object MUST always be instantiated, even if the log can contain Notifications from only one engine.
Please be aware that the nlmLogEngineTAddress may not uniquely identify the SNMP engine from which the Notification was received. For example, if an SNMP engine uses DHCP or NAT to obtain ip addresses, the address it uses may be shared with other network devices, and hence will not uniquely identify the SNMP engine. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.6 |
nlmLogEngineTDomain |
OBJECT IDENTIFIER |
read-only |
Indicates the kind of transport service by which a Notification was received from an SNMP engine. nlmLogEngineTAddress contains the transport service address of the SNMP engine from which this Notification was received.
Possible values for this object are presently found in the Transport Mappings for SNMPv2 document (RFC 1906 [8]). |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.7 |
nlmLogContextEngineID |
OCTET STRING{(5,32)} |
read-only |
If the Notification was received in a protocol which has a contextEngineID element like SNMPv3, this object has that value. Otherwise its value is a zero-length string. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.8 |
nlmLogContextName |
OCTET STRING{(0,255)} |
read-only |
The name of the SNMP MIB context from which the Notification came. For SNMPv1 Traps this is the community string from the Trap. |
This object is implemented as defined in the corresponding MIB files. |
1.3.6.1.2.1.92.1.3.1.1.9 |
nlmLogNotificationID |
OBJECT IDENTIFIER |
read-only |
The NOTIFICATION-TYPE object identifier of the Notification that occurred. |
This object is implemented as defined in the corresponding MIB files. |
