[rrd-users] Re: 95th percentile reporting?

Pete,
the main idea is to do the following:

1) load an array that contains the set of data you want the 95th %'ile
from
2) sort the array (numerically)
3) calculate the index of the array that is 95% of the size of the array
(increment if not whole number)
4) use the element at that new index for your 95%'ile

that should get you going...

[rrd-users] 95th percentile reporting?






List,

For those of you who bill customers based on 95th percentile traffic,
what methods are you using to retrieve the 95th percentile values from
your RRDs and hand the data to your billing engine?
