[rrd-users] AW: AW: calculating percentage

[Thorsten Volkmer-Wolf]

I Think you will have to provide additional RRAs in your RRD, where you'd store the percentage values. It's up to you to calculate those valuas in your script which is collecting the datas or to use the bultin calculation possibilities with CDEF (see the tutorials).

Hope this helps??

Regards,

the problem is this (for example):

if the maximum rate for a day for http protocol is x MB/s,
how can i divide x with the total maximum rate?

(how can i have a variable x with the maximum rate for http..?)
