EVNTAGENT-MIB

Description: EVNTAGENT-MIB module

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.

EVNTAGENT-MIB is a Microsoft-oriented SNMP module (its OID arc includes "microsoft" and "eventlog") that acts as an SNMP bridge to the Windows Event Log, exposing logged event records to standard SNMP management tools. It surfaces individual event entries carrying free-form event text, the originating system and user, an event type/category classification, and up to six generic variable slots holding event-specific insertion data. This is fundamentally a software-status and fault-monitoring MIB: it lets an NMS detect application crashes, failed logons, service stops, or security-audit events recorded in the Windows Event Log without a native Windows monitoring agent. It has no explicit stated dependency beyond standard SNMPv2-SMI imports, though it is commonly deployed alongside Microsoft's or a third-party SNMP agent extension for Windows. It's typically deployed on Windows servers or workstations running an SNMP agent extension that forwards Event Log activity to a network management system. Engineers can download the EVNTAGENT-MIB file directly to load it into their MIB browser.

An admin polling this MIB would read event records keyed by eventType and eventCategory, with eventText giving the human-readable message, eventUserId identifying the triggering account, and eventSystem naming the source host; eventVar1 through eventVar6 hold structured insertion strings such as a service name or error code. A spike of error-classified eventType entries or repeated critical eventCategory records for the same eventSystem would signal an escalating problem on that host worth investigating.
