Which MIBs are commonly leveraged by NPM for device monitoring, and why are they important?

• A. SNMPv3 MIBs only
• B. IF-MIB, IP-MIB, TCP-MIB, HOST-RESOURCES-MIB; used to fetch interface counters, IP addressing, and system resources; standardization aids accurate monitoring
• C. Only IF-MIB and IP-MIB
• D. MIBs are not relevant for NPM

Answer: (B)

Monitoring relies on standardized MIBs that define what data devices expose and how to read it. This consistency lets NPM collect metrics from diverse gear in the same way, making trends, baselines, and alerts reliable across vendors. IF-MIB provides interface-level data, including counters and status for each network port. This is the backbone for understanding bandwidth, utilization, errors, and overall link health. IP-MIB brings in IP-address information and basic IP statistics tied to interfaces, letting you map where addresses live on devices and track IP-level activity and drops. TCP-MIB covers TCP connection metrics and states, giving visibility into how many active or established connections exist, segments in and out, and related performance indicators. HOST-RESOURCES-MIB exposes system resources such as CPU, memory, and storage, enabling monitoring of resource contention and capacity planning. Because these MIBs are widely implemented and standardized, NPM can gather accurate, interoperable data across many devices. Limiting to SNMPv3 MIBs only would miss the actual metrics captured by these standard MIBs; using only a subset like IF-MIB and IP-MIB omits TCP and host-resource data; and saying MIBs aren’t relevant contradicts how NPM collects essential performance information.
