Division IIRC it's not rounded, so a number of small flows can be hidden in the 'noise'... As with any fixed point calc it's possible for "values may not total 100% due to rounding" (or truncation in this case).
Here's some #s from my ntop instance: Local IP Traffic Host IP Address Data Sent Data Rcvd 192.168.42.6 192.168.42.6 97.8 KB 71.5 % 39.1 KB 28.5 % piglet 192.168.42.1 7.2 KB 5.3 % 5.3 KB 3.9 % swallowtail 192.168.42.3 31.9 KB 23.3 % 92.4 KB 67.6 % Total Traffic Data Sent Data Rcvd Used Bandwidth 136.8 KB 136.8 KB 136.8 KB 59.0 Kbps The actual "total" is 136.9 KB and the sum of the %s is 100.1 Also remember, these are scaled figures - check the suffix for KB vs MB vs GB vs nothing (bytes) I had at once point a patch to scale all of these the same, but nobody was interested... -----Burton -----Original Message----- From: Davinder Singh - McLean [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 17, 2002 11:20 AM To: 'Burton M.

Can someone tell me the way the percentage is calculated. The other thing is ntop at end of data received/sent says it has been up and running for 1 day but when we open a host , it indicates running for two days. _______________________________________________ Ntop mailing list [EMAIL PROTECTED] http://listmanager.unipi.it/mailman/listinfo/ntop _______________________________________________ Ntop mailing list [EMAIL PROTECTED] http://listmanager.unipi.it/mailman/listinfo/ntop
