I have small issue with Ntop 3.3.11-dev that I wonder if anyone else
sees. Basically at some point the Libpcap Dropped Packet counter starts
to go crazy increamenting way to fast, basically the more you refresh
the page the higher the stats go. I noticed it a few weeks ago when I
was troubleshooting the stability issues on Centos 5.3 but it didn't
come back until now. This instance of Ntop has been up for 17-18days now
when suddenly the dropped back went from 2% up and up....
Here is a little example with the time I hit refresh
6:54
Dropped (libpcap) 35.2% 2,104,631,637
6:57
Dropped (libpcap) 40.4% 2,413,942,059
8:40
Dropped (libpcap) 45.4% 2,735,237,999
8:42
Dropped (libpcap) 50.7% 3,057,525,920
I let it be until the next morning this time I refreshed the page asx
fast as I could and look what happens.
6:38
Dropped (libpcap) 71.3% 4,666,158,554
6:38
Dropped (libpcap) 74.2% 4,854,085,280
6:38
Dropped (libpcap) 77.0% 5,042,015,632
6:38
Dropped (libpcap) 79.9% 5,229,949,802
6:39
Dropped (libpcap) 82.8% 5,417,891,784
So within 1 min it thinks it has seen 1 Billion packets. :) The network
is a DS3 but it doesn't do anywhere near 10million packets/sec!
My full config and problem report page can be grabbed from my early
post [7/24/09 7:00AM Subject: Centos 5.3 Unstable?]
