Re: SNMP Measurements for MICE?

by Jeremy Lumby

Depends on how you look at it. More sampling shows more extremes. If you sample at 1 minute, and it were to shoot up to 12G for a minute or two, and then drop below 1G for a minute or two, you would see both the 12G high, and the 1G low. If you look at the same traffic on a five min sample rate, you would see it at about 6G, and you would not see the 1G low, or the 12G high. Personally I like higher sample rates since if you are sizing a connection to the exchange, and you do not want to have any loss, in the above example you would have loss if you only purchased a 10G circuit, and if you were looking only at 5 minute sample rates, you would have no clue why you were getting intermittent packet loss. -----Original Message----- From: MICE Discuss [mailto:MICE-DISCUSS@LISTS.IPHOUSE.NET] On Behalf Of Hannigan, Martin Sent: Wednesday, August 12, 2015 12:24 PM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] SNMP Measurements for MICE?

a secant line is a secant line, be it a ray/segment/line/etc between points spaced 1 second, ten seconds, or ten minutes apart, no? (sorting line segments by their n-tile magnitude, be it at 95% or some other interval, seems decoupled from the measurement/secant interval) if my graph theory is bad, let me know :) -Tk On Wed, Aug 12, 2015 at 9:11 AM, Hannigan, Martin <marty(a)akamai.com> wrote: > > All, > > Isn’t 95th @ 1m unusual and non-standard? > > http://micelg.usinternet.com/export/graph_385.html > > Best, > > -M< > > > > >

All, Isn’t 95th @ 1m unusual and non-standard? http://micelg.usinternet.com/export/graph_385.html Best, -M<
