EVAPA-MIB

Description: Manages EVAPA (Evolved Virtual Access Point Aggregator) or related wireless access aggregation equipment.

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.

EVAPA-MIB is an HP MIB (object prefix 'hpevapa') most consistent with HP StorageWorks Enterprise Virtual Array (EVA) Performance Advisor, used to monitor performance counters and threshold-based alerting for HP EVA SAN storage arrays. It exposes an array/object/counter hierarchy: array identity, a managed object (such as a LUN, disk group, or controller) within that array, a named performance counter on that object, a configured detection threshold, and the counter's current measured value. Its primary monitoring use is software/performance-health tracking of the storage array — comparing actual counter values against configured detection levels to flag performance degradation, functioning much like a threshold/alarm mechanism for storage I/O performance rather than physical hardware sensors. It is most plausibly tied to HP's EVA Performance Advisor management software rather than an IETF standard MIB. It is deployed in enterprise SAN environments where HP EVA storage arrays are monitored for performance anomalies such as elevated latency or IOPS saturation. Engineers can download the EVAPA-MIB file directly to load it into their MIB browser.

hpevapaArray-ID/hpevapaArray-Name identify a monitored EVA storage array, hpevapaObject-ID/hpevapaObject-Type/hpevapaObject-Name identify a specific managed object within it (for example a LUN or disk group), and hpevapaCounter-Name names a specific performance metric on that object. An operator polls hpevapaActual-Value against the configured hpevapaDetect-Level to detect when, for example, latency or I/O load on a LUN has crossed its performance threshold, indicating the array or a component of it is becoming a bottleneck.
