All Implemented Interfaces:

Collectable

public class SnmpNodeCollector
extends AggregateTracker

The SnmpNodeCollector class is responsible for performing the actual SNMP data collection for a node over a specified network interface. The SnmpNodeCollector implements the SnmpHandler class in order to receive notifications when an SNMP reply is received or error occurs. The SnmpNodeCollector is provided a list of MIB objects to collect and an interface over which to collect the data. Data collection can be via SNMPv1 GetNext requests or SNMPv2 GetBulk requests depending upon the parms used to construct the collector.
