VIP stats required

AVR / telemetry streaming is the way to do any real trending, both are free - license wise.

A quick solution although less robust is to use  bigtop,   it takes some playing with the switchs , but it might give you what you are looking for.

from CLI - from bash,

uptime    <---tell you how long the box has been up

bigtop -vname -nodes 0 -reqs     <---should give you a starting point you can divide out days into requests....

you can clear stat counters on the VS - and it will give you a starting point and time use that on a daily check - or get crazy and write a cronjob to kick off XX times a day /week,   with the -once command

Quick help =  bigtop --help
longer help = man bigtop
