Function Documentation

void agentx_child

(

int

rank

)

Run the AgentX sub-agent as a separate process.

The child will insulate itself from the rest of OpenSER by overriding most of signal handlers.

1) Registers itself with the Master Agent 2) Initializes all of the SNMPStats modules scalars and tables, while simultaneously registering their respective SNMP OID's and handlers with the master agent. 3) Repeatedly checks for new SNMP messages to process

Note:

This function never returns, so it should always be called from a sub-process.
