Well, that explains the interval. The example I posted was one of the
smallest loss amounts, but what is an acceptable or expected loss level?
In the last 6 hours my setup does have a 1448 out of 206031, or .7%. So
.005% seems small, is .7% small?
I am running the default local.bro, and it does have misc/scan loaded. I
turn that off and see if I still see loss, but if 1% or less is considered
normal loss even for a low load and small traffic, then I guess it is less
