A standardized framework for extensible SNMP agents. It defines processing entities called master agents and subagents, a protocol (AgentX) used to communicate between them, and the elements of procedure by which the extensible agent processes SNMP protocol messages.
This very real need to dynamically extend the management objects within a node has given rise to a variety of "extensible agents", which typically comprise:
- A "master" agent that is available on the standard transport address and that accepts SNMP protocol messages.
- A set of "subagents" that each contain management instrumentation.
- A protocol that operates between the master agent and subagents, permitting subagents to "connect" to the master agent, and the master agent to multiplex received SNMP protocol messages amongst the subagents.
- A set of tools to aid subagent development, and a runtime (API) environment that hides much of the protocol operation between a subagent and the master agent.
