ms_elemList

public static NamedSnmpVar[] ms_elemList

The keys that will be supported by default from the TreeMap base class. Each of the elements in the list are an instance of the SNMP Interface table. Objects in this list should be used by multiple instances of this class.

SYSTEM_OID

public static final String SYSTEM_OID

The SYSTEM_OID is the object identifier that represents the root of the system information in the MIB forest. Each of the system elements can be retrieved by adding their specific index to the string, and an additional Zero(0) to signify the single instance item.

Constructor Detail

SystemGroup

public SystemGroup(InetAddress address)

The class constructor is used to initialize the collector and send out the initial SNMP packet requesting data. The data is then received and store by the object. When all the data has been collected the passed signaler object is notified using the notifyAll() method.

Parameters:

address - TODO
