public class JMXNodeCollector
extends Object

The JMXNodeCollector class is responsible for performing the actual JMX data collection for a node over a specified network interface. The JMXNodeCollector implements the SnmpHandler class in order to receive notifications when an JMX reply is received or error occurs. The JMXNodeCollector is provided a list of MIB objects to collect and an interface over which to collect the data. Data collection can be via JMXv1 GetNext requests or JMXv2 GetBulk requests depending upon the parms used to construct the collector.
