Introduction to Subagent
Programming
Simple Network Management Protocol (SNMP) lets workstation-based applications
manage resources that reside on remote devices supplied by different vendors. These
SNMP-compliant applications, known as “managers,” communicate with SNMP agents
on the remote devices. An agent is an SNMP-compliant software product that accepts
queries and change requests from managers about resources to which the agent has
access.
NonStop SNMP Support
Tandem provides an SNMP agent for its NonStop systems. As Figure 1-1 illustrates, the
NonStop agent interacts with subagents that reside on the same or remote NonStop
systems. Each subagent handles manager requests forwarded by the NonStop agent for
hardware or software resources the subagent is responsible for. A manager can send
requests to retrieve or change information about a subagent’s resources when the
Management Information Base (MIB) describing those resources has been compiled and
installed on the manager station.
