Package uk.co.westhawk.snmp.beans

Class NcdPerfDataBean

java.lang.Object
uk.co.westhawk.snmp.beans.SNMPBean
uk.co.westhawk.snmp.beans.NcdPerfDataBean
All Implemented Interfaces:
PropertyChangeListener, EventListener
public class NcdPerfDataBean extends SNMPBean implements PropertyChangeListener

This bean collects information about a IBM Network Computer.

It provide the following data:

  • the speed of the Ethernet Card
  • the available memory in bytes
  • the name of the user that is logged in

A message will be set if some of the data is not available

This class uses the NCDware v3.2 MIB, which was very kindly provided to me by Network Computing Devices, inc (NCD). This MIB is an extention of the older versions of the MIB

The properties in the parent classes should be set, before calling the action() method. Via a PropertyChangeEvent the application/applet will be notified.
