Category: SNMP Framework

Description: Defines managed objects for the AgentX protocol, which distributes SNMP agent implementation across a master agent and multiple subagents.

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

What Is AGENTX-MIB?

AGENTX-MIB, standardized in RFC 2742, defines the conformance requirements for implementations of the AgentX protocol, a vendor-neutral IETF mechanism that lets a single SNMP master agent aggregate management data from multiple independently running subagent processes on the same host. Rather than exposing device hardware or software counters itself, it is fundamentally an architectural/protocol-compliance module concerned with how SNMP agent implementations are structured. It therefore has no hardware/software status objects of its own -- no uptime, temperature, or interface data -- since that data would instead come from whichever MIBs the subagents themselves implement. It builds directly on the SNMPv2-SMI and SNMPv2-CONF conformance framework and effectively depends on the separately-specified AgentX wire protocol (RFC 2741) that it requires master agents to implement. It is relevant to any host running a modular, multi-process SNMP agent architecture (master agent plus subagents), a pattern common in Unix/Linux-based network devices such as those running Net-SNMP. Reviewing the AGENTX-MIB OID list mainly reveals conformance and compliance group identifiers rather than any device data objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in AGENTX-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 (IETF); applies to any host running a modular SNMP agent (master agent + subagents), e.g. Net-SNMP-based network devices

Monitoring Examples

AGENTX-MIB is essentially a conformance/compliance module for implementations of the AgentX master-agent protocol rather than a source of device data; no sample runtime objects were identified, so no concrete polling scenario can be described from this module alone -- actual monitorable device data would come from whatever MIBs the subagents register, not from AGENTX-MIB itself.
