Sorry for the attachment, but these graphs are the result of my work with
Ntop, and they show a trend of false readings. After about an hour of use
on our (about 50% loaded) 10Mbit external link I see the traffic reported by
Ntop drop off. When I check the console I notice that there are 30 to 45
second pauses between TCP session announcements. There's about one minute
between pauses, meaning that Ntop is only reporting about 60% of the actual
traffic (rough guess).
You can see where Ntop has been restarted and shortly after the reported
traffic rate drops dramatically. The one hour graph shows gaps where Ntop
was unable to reply to my requests for data collection. If any more
information would help please just let me know. Thanks.
