TRIDIUMR3-MIB

Description: Manages Tridium Niagara R3 building automation and control network devices via SNMP.

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.

TRIDIUMR3-MIB is a vendor-specific MIB for Tridium's Niagara Framework (Niagara R3), a software platform used in building automation and control (BAS/BMS) systems that unify HVAC, lighting, energy, and other building subsystems under one SNMP-manageable umbrella. It exposes alarm and event data generated by the Niagara station, including alarm records, their acknowledgment state, source, and classification, rather than raw hardware sensor telemetry. As a monitoring tool it is primarily used to track the health and operational status of the building automation system itself, surfacing active and historical alarms, whether they have been acknowledged, and what device or point triggered them, which functions as an early-warning system for equipment or software faults within the automated building. It does not appear to import from other standard IETF MIBs, reflecting its self-contained enterprise design typical of Tridium's proprietary alarm model. It is typically deployed in commercial building management systems where a Niagara supervisor or JACE controller aggregates alarms from HVAC controllers, energy meters, and other automation devices for centralized NOC-style monitoring. Engineers can download the TRIDIUMR3-MIB file directly to load it into their MIB browser.

An administrator would poll alarmTable/alarmTableEntry to retrieve active alarm records, each identified by a uuid and timestamp, and check ackState and ackRequired to see whether operations staff have acknowledged a fault. The sourceState and source fields identify which building-automation point or device raised the condition, while alarmClass groups alarms by severity or category (e.g., HVAC fault vs. security). A steady increase in unacknowledged high-class alarms in alarmTable would indicate a developing equipment problem, such as an HVAC unit repeatedly tripping a fault condition, that needs operator attention.

Tracks alarms and provides action control for Tridium Niagara R3 building automation and HVAC station management systems.
