This application transverses the network, starting with the node it is run from and returns statistics from all reachable nodes within a specifiable depth

Parameters:

• -depth : The maximum depth to go to in the tree [15].
• -maxwait : The number of seconds to wait for responses before timing out [30].
• -senddelay : The number of milliseconds to wait between sending root request capsules. Helps decrease network strain [500].
• -cachetime : The number of seconds for a return capsule to wait in the cache and for a request capsule to keep its tree information [180].
• -returnwait : The maximum number of milliseconds to wait for return capsules before sending what has already been accumulated [10000].
• -returntimeout : The maximum number of milliseconds to wait for unreturned capsules before timing out [60000].

Fields

· defaults

Summary  |  Top

   private static final String[] defaults

   private final int LOG_LEVEL

The logging level messages issued by this class are issued at. Gross hack to hide the grosser hack that is `L'.

   private byte depth

The maximum depth that this request will go into the network before cancelling itself (similar to TTL)

   private int maxwait

Seconds to wait for activity before the run is stoped

   private int rootsenddelay

Msec to wait between sending root request packets (lessens network strain)

   private int retcount

Keeps track of the number of returned packets

   private int cachetime

Parameters passed on to the capsule

   private int returnwait

Parameters passed on to the capsule

   private int returntimeout

Parameters passed on to the capsule

   private Vector waitingon

Keeps track of the nodes that have sent requests that have not been replied to

   private Vector unmatchedrets

Keeps track of the parents of the nodes that have returned, but that the application was not waiting on.

Sometimes return capsules come from the child before the parent, this way they are not lost from the tracking system

Constructors

Summary  |  Top

   public StatsApplication()  throws Exception

Construct a non-GUI stats app.

Doesn't do anything.

   public synchronized void receive(Capsule unknownCap) 

Handle the incoming capsule and tell it to print its information

Overrides:

receive in class Application

   public void run() 

Sends out the root request capsules to all neighboring nodes then sleeps forever

Implements:

run in interface Runnable

   private void sendRootCapsules() 

Sends the root request capsule to all neighboring nodes

   public void setArgs(KeyArgs k)  throws InvalidKeyArgsException

Parse command line arguments.

See the class description for a list of the arguments and their meaning.

Overrides:

setArgs in class Application

   public void start()  throws Exception

Register the protocol and start the thread

Overrides:

start in class Application
