Category: Network Monitoring (RMON), Quality of Service

Description: Extends the RMON framework for Real-time Application Quality-of-Service Monitoring, exposing end-to-end application QoS data from endpoints.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring RAQMON-MIB with a free 30-day trial of IPNetwork Monitor.

What Is RAQMON-MIB?

RAQMON-MIB is an IETF standards-track MIB, published as RFC 4711 by the RMON MIB Working Group, that extends the RMON framework to support Real-Time Application Quality-of-Service Monitoring (RAQMON) — collecting end-to-end QoS data reported by application endpoints themselves rather than inferred from network devices. Its central raqmonParticipantTable records per-session participant details (raqmonParticipantAddr, raqmonParticipantName, raqmonParticipantAppName, source/destination payload type and DSCP/L2 priority, session start/end dates), while raqmonQoSEnd2EndNetDelay and raqmonQoSInterArrivalJitter expose the actual measured delay and jitter values that determine perceived call or media quality. A raqmonSessionAlarm notification correlates a set of these objects so a manager can be pushed a QoS problem in real time rather than having to poll continuously. Because the data originates at application endpoints (e.g., a VoIP phone or media gateway), it depends on that endpoint implementing the RAQMON Data Export protocol to populate the MIB, and it is deployed alongside real-time media applications such as VoIP or video conferencing systems. Standards-focused implementers can consult the RAQMON-MIB RFC to see exactly which application QoS objects are defined for export.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAQMON-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

vendor-neutral, standards-based MIB (RFC 4711), not tied to a specific manufacturer — implemented by RAQMON-capable application endpoints

Monitoring Examples

An operator subscribes to raqmonSessionAlarm and cross-references raqmonQoSEnd2EndNetDelay and raqmonQoSInterArrivalJitter for the affected raqmonParticipantIndex; sustained high jitter values reported directly from an endpoint's raqmonParticipantTable entry indicate real-time media quality is degraded even if intermediate network devices show no congestion.

What Can Be Monitored

end-to-end network delay per session
inter-arrival jitter per session
session participant identity and application name
session start/end timestamps
QoS session alarm notifications

How to Use in IPNetwork Monitor

Example using raqmonConfigRaqmonPdus OID:

Select a device implementing RAQMON-MIB as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type raqmonConfigRaqmonPdus into the Find box to locate it in the OID tree, then select it and click OK. It reports the count of RAQMON PDUs received by the Collector. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in PDUs), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

U32 raqmonQosTime	1.3.6.1.2.1.16.31.1.1.2.1.1	Unsigned32	not-accessible	Time of this entry measured from the start of the corresponding participant session.
raqmonSession	1.3.6.1.2.1.16.31.1.1
NTF raqmonSessionAlarm	1.3.6.1.2.1.16.31.0.1			A notification generated by an entry in the raqmonSessionExceptionTable.
raqmonSessionExceptionEntry	1.3.6.1.2.1.16.31.1.2.2.1		not-accessible	A conceptual row in the raqmonSessionExceptionTable.
U32 raqmonSessionExceptionIAJitterThreshold	1.3.6.1.2.1.16.31.1.2.2.1.3	Unsigned32	read-create	Threshold for jitter. The value during a session must be greater than or equal to this value for an exception to be created.
U32 raqmonSessionExceptionIndex	1.3.6.1.2.1.16.31.1.2.2.1.2	Unsigned32	not-accessible	An index that uniquely identifies an entry in the raqmonSessionExceptionTable. Management applications can determine unused indices by performing GetNext or GetBulk operations on the Table.
U32 raqmonSessionExceptionLostPacketsThreshold	1.3.6.1.2.1.16.31.1.2.2.1.5	Unsigned32	read-create	Threshold for lost packets in units of tenths of a percent. The value during a session must be greater than or equal to this value for an exception to be created.
U32 raqmonSessionExceptionNetRTTThreshold	1.3.6.1.2.1.16.31.1.2.2.1.4	Unsigned32	read-create	Threshold for round-trip time. The value during a session must be greater than or equal to this value for an exception to be created.

A newly-created conceptual row must have all the read-create objects initialized before becoming 'active'. A conceptual row that is in the 'notReady' or 'notInService' state MAY be removed after 5 minutes. No writeable objects can be changed while the row is active.
raqmonSessionExceptionTable	1.3.6.1.2.1.16.31.1.2.2		not-accessible	This table defines thresholds for the management station to get notifications about sessions that encountered poor quality of service. The information in this table MUST be persistent across agent reboots.

RFC description

Monitors real-time application QoS metrics including jitter, delay, and packet loss for VoIP sessions.

Start monitoring vendor-neutral, standards-based MIB (RFC 4711), implemented by RAQMON-capable VoIP/video endpoints 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.
