Re: [Sipdht-devel] results for gsim-sipdht2

[stefano <st....@gm...>]

Currently our statistics (in the window statusbar) are defined
in the following way:

Time: seconds from the startup of the program (refreshed every 5 sec)

Peers: total number of "live peers" in the simulation

Sessions: total number of sessions of "live peers" in the overlay
               (so 2 peers => 1 session for each peer = 2 sessions)

Packets sents: total packets sents by all "live peers"
                         for all current sessions

Received: total packets received by all "live peers"
                 for all current sessions

So, peers, sessions, packets sents and received are not cumulative
but this data represents only the "current state of the overlay",
because we want to know how much traffic is produced by the
active peers.

If you need cumulative data it must be implemented:
- If you need a fast way to count peers probably you can write
  to the log file and then doing "grep" in the logfile
- if you need cumulative counters for packets you have to modify
  gtk_statusbar_update in gsim-sipdht2.c and made counter variables
  static.

Cheers,
Stefano
