Method Detail

snmpInternalError

public void snmpInternalError(org.opennms.protocols.snmp.SnmpSession session,
                              int err,
                              org.opennms.protocols.snmp.SnmpSyntax pdu)

Defined by the SnmpHandler interface. Used to process internal session errors.

Specified by:

snmpInternalError in interface org.opennms.protocols.snmp.SnmpHandler

Parameters:

session - The SNMP session in error.

err - The Error condition

pdu - The pdu associated with this error condition

snmpTimeoutError

public void snmpTimeoutError(org.opennms.protocols.snmp.SnmpSession session,
                             org.opennms.protocols.snmp.SnmpSyntax pdu)

This method is define by the SnmpHandler interface and invoked if an agent fails to respond.

Specified by:

snmpTimeoutError in interface org.opennms.protocols.snmp.SnmpHandler

Parameters:

session - The SNMP session in error.

pdu - The PDU that timed out.

snmpReceivedPdu

public void snmpReceivedPdu(org.opennms.protocols.snmp.SnmpSession session,
                            int cmd,
                            org.opennms.protocols.snmp.SnmpPduPacket pdu)

This method is defined by the SnmpHandler interface and invoked when the agent responds to the management application.

Specified by:

snmpReceivedPdu in interface org.opennms.protocols.snmp.SnmpHandler

Parameters:

session - The session receiving the pdu.

cmd - The command from the pdu.

pdu - The received pdu.

walk

public java.util.Vector walk(java.lang.String host,
                             java.lang.String commName,
                             java.lang.String oid)

It will walk the entire agent tree, or a subsection as defined by the parameters specified.

Parameters:

host - Remote host IP Address which is to be queried through SNMP.

commName - Community name String.

oid - Object id from which the tree is to be traversed.

Returns:

Vector of the result of Walk, containing objects of class SnmpVarBind.

snmpGet

public java.util.Vector snmpGet(java.lang.String host,
                                java.lang.String commName,

Returns the value of specified oid as parameter

Parameters:

host - Remote host IP Address which is to be queried through SNMP.

commName - Community name String.

oid - Object id from which the value is to be obtained

Returns:

Vector of the result of Get, containing object of class SnmpVarBind.
