Detailed Description

AgentX interface for Server interface to net-snmp agent for SNMP support.

Requires WITH_SNMP=1 in build and –with-snmp=true CLI parameter at runtime.

Function Documentation

agt_ypsnmp_agentx_check_io()

void agt_ypsnmp_agentx_check_io

(

void

)

Check if any SNMP messages to process.

Adapted from net-snmp agent Only present if WITH_SNMP=1

agt_ypsnmp_agentx_cleanup()

void agt_ypsnmp_agentx_cleanup

(

void

)

Cleanup the agt_ypsnmp AgetnX module.

Releases any memory allocated and stops listening on the network. Only present if WITH_SNMP=1

agt_ypsnmp_agentx_connected()

boolean agt_ypsnmp_agentx_connected

(

void

)

Check if the AgentX agent succ connected to the master agent.

Only present if WITH_SNMP=1.

Returns

TRUE if AgentX was succ connected to master:
FALSE otherwise, which may indicate that the master agent is not up and running or the AgentX agent could not connect to master.

Here is the caller graph for this function:

agt_ypsnmp_agentx_handle_response()

int agt_ypsnmp_agentx_handle_response	(	int	op,
		netsnmp_session *	session,
		int	reqid,
		netsnmp_pdu *	pdu,
		void *	magic
	)

Handle the AgentX response.

AgentX handling utility routines Only present if WITH_SNMP=1

Parameters

op	SNMP op code
session	The net-snmp session
reqid	The request id of this pdu ( 0 for TRAP)
pdu	The snmp pdu information
magic	opaque handler

Returns

Returns 1 if successful, 0 if error

agt_ypsnmp_agentx_init()

status_t agt_ypsnmp_agentx_init

(

void

)

Initialize the agt_ypsnmp AgentX module.

Phase 2 initialization

Only present if WITH_SNMP=1

Returns

status

agt_ypsnmp_agentx_synch_input()

int agt_ypsnmp_agentx_synch_input	(	int	op,
		netsnmp_session *	session,
		int	reqid,
		netsnmp_pdu *	pdu,
		void *	magic
	)

Synch input.

AgentX handling utility routines. Only present if WITH_SNMP=1.

Parameters

op	SNMP op code
session	The net-snmp session
reqid	The request id of this pdu ( 0 for TRAP)
pdu	The snmp pdu information
magic	opaque handler

Returns

Returns 1 if successful, 0 if error

agt_ypsnmp_get_agentx_scb()

ses_cb_t * agt_ypsnmp_get_agentx_scb

(

void

)

Get the AgentX specific session control block.

AgentX and master agents both have this block. The SCB is saved internally as a stitic pointer.

Only present if WITH_SNMP=1

Returns

AgentX Session Control Block to hold RCB and other statistics
NULL, if there is no any open sessions with master agent
