A supervisor for the SNMP agent Processes

This is the top supervisor for the agent part of the SNMP application. There is always one supervisor at each node with an SNMP agent (master agent or sub-agent).

Summary

Functions

start_master_sup(Opts)

Starts a supervisor for the SNMP agent system. The supervisor starts all involved SNMP processes, including the master agent. Sub-agents should be started by calling start_subagent/3.

start_sub_agent(ParentAgent, Subtree, Mibs)

Starts a sub-agent on the node where the function is called. The snmpa_supervisor must be running.

start_sub_sup(Opts)

Starts a supervisor for the SNMP agent system without a master agent. The supervisor starts all involved SNMP agent processes, but no agent processes. Sub-agents should be started by calling start_sub_agent/3.

stop_sub_agent(SubAgentPid)

Stops the sub-agent on the node where the function is called. The snmpa_supervisor must be running.
