Description: ANS CO+RE network alarm and fault notification management for high-speed services.

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 ANS-ALARM-MIB?

ANS-ALARM-MIB is a network alarm and event management MIB from ANS CO+RE Systems (a legacy high-speed data-services/ISP infrastructure provider), designed to report and log fault/event conditions from network equipment for centralized alarm correlation. It exposes an event table recording each event's name, community, treatment (how it should be handled/escalated), last-sent time, and owner, plus controls for log administration and sizing, and a discrimination flag for filtering which network events actually generate alarms. Its monitoring value is entirely in fault/status visibility: eventTable/eventEntry effectively functions as an alarm history log, letting an operator see which fault conditions have fired repeatedly (via eventLastTimeSent) and whether alarm generation is being filtered by discriminateNtEvents, which would explain "missing" alarms. It does not show an explicit dependency on other standard MIBs, appearing to be a self-contained enterprise alarm-log design. It is typically deployed within ANS CO+RE's own network operations infrastructure for centralized fault and alarm log management across their high-speed service network, and administrators can download the ANS-ALARM-MIB file to integrate it into their alarm-management tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in ANS-ALARM-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 operator would poll eventTable/eventEntry by eventIndex to review eventName, eventTreatment, and eventLastTimeSent for recurring fault conditions, and check discriminateNtEvents to confirm certain event classes aren't being suppressed from alarm generation. logSize approaching capacity while logAdminStatus remains enabled would indicate the alarm log needs to be rotated or expanded before new events start overwriting old ones.

What Can Be Monitored

event/alarm log entries
event treatment/escalation setting
last alarm time per event
alarm log size and admin status

INT eventIndex	1.3.6.1.4.1.193.96.115.2.1.1.1.1	INTEGER	read-only	An index that uniquely identifies an entry in the event table. Each such entry defines one event that is to be generated when the appropriate conditions occur.
STR eventName	1.3.6.1.4.1.193.96.115.2.1.1.1.2	DisplayString	read-only	The name of the associated event, normally the name of the associated trap.
INT eventTreatment	1.3.6.1.4.1.193.96.115.2.1.1.1.3	INTEGER	read-write	Defines how the system shall treat this event. In the case of log, an entry is made in the log table for each event. In the case of snmp-trap, an SNMP trap is sent to one or more management stations.
STR eventCommunity	1.3.6.1.4.1.193.96.115.2.1.1.1.4	DisplayString	read-write	If an SNMP trap is to be sent, it will be sent to the SNMP community specified by this octet string.
DAT eventLastTimeSent	1.3.6.1.4.1.193.96.115.2.1.1.1.5	DateAndTime	read-only	The value of sysUpTime at the time this event entry last generated an event. If this entry has not generated any events, this value will be zero.
STR eventOwner	1.3.6.1.4.1.193.96.115.2.1.1.1.6	DisplayString	read-write	The entity that configured this entry and is therefore responsible for its contents. This variable is suggested to contain one or more of the following: IP address, management station name, network manager's name, location, or phone number. In some cases the agent system itself will be the owner of an entry (e.g. prior to a manual configuration of an entry). In these cases, this string shall be set to a string starting with 'monitor'. Note that this variable will only act as a voluntary access control. It does not prevent uncooperative parties from changing an entry of another owner.
INT discriminateNtEvents	1.3.6.1.4.1.193.96.115.2.1.2	INTEGER	read-write	Indicates whether events generated by an NT shall be discarded or not. include means that NT events shall be shown. exclude means that NT events are hidden when displaying the event log, the current alarm list, and when sending traps.

INT logAdminStatus	1.3.6.1.4.1.193.96.115.2.2.1	INTEGER	read-write	The administrative status of the log as a whole. Up means that logging shall take place of all events that are to be logged. Down means that no logging of events shall take place.

INT logEventIndex	1.3.6.1.4.1.193.96.115.2.2.3.1.2	INTEGER	read-only	The event entry that generated this log entry. The log identified by a particular value of this index is associated with the same eventEntry as identified by the same value of eventIndex.
STR logEventName	1.3.6.1.4.1.193.96.115.2.2.3.1.3	DisplayString	read-only	The name of the logged event.
