[rrd-users] 95th Percentile - Values stored inside RRD file

[Hwee Khoon, Neo]

Hi everyone,

I got some questions on 95th percentile and RRD which I hope someone can
enlighten.

1) Is .1.3.6.1.2.1.31.1.1.1.6.XXX (e.g.
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifHCInOctets.XXX = Counter64)

where XXX refers to a particular interface/sub interface

the correct OIDs to use?


2) Since 95th percentile is measuring the rate of transfer, that means I
will need to add

.1.3.6.1.2.1.31.1.1.1.10.XXX
(ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifHCOutOctets.XXX) to InOctets to
obtain the exact rate of transfer over the interface? Am I correct?



3) I noticed the raw data inside RRD file contains the cumulative figure
(e.g. the octet count is always increasing). Is it possible for me to
configure RRD such that it computes the transfer speed and then store them
into the file? Instead of dumping the exact figure to the file.


Thanks!

Rgds,
HK
