Detailed Description
SNMP statistic module, master agent connection.This file defines all functions required to establish a relationship with a master agent.
Definition in file sub_agent.c.
Function Documentation
| void agentx_child | ( | int | rank | ) |
Creates a child that will become the AgentX sub-agent. The child will insulate itself from the rest of OpenSER by overriding most of signal handlers.
Definition at line 126 of file sub_agent.c.
References initialize_agentx(), NULL, and sigterm_handler().
| static int initialize_agentx | ( | void | ) | [static] |
This function:
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.
