[rrd-users] can't understand MAX snmp value

[Vergnault, Fabrice]

hi
(excuse for my poor english)

when i fetch MAX value from my RRD, I obtain strange value:
this MAX value indicate 11.9Mo (~96Mbits) on a link can do 34Mbits !!!!

my snmp polling is all 5 minutes

see my rrdtool info on my rrd file:

filename = "XXX.XXX.XXX.XXX_Se6_0.rrd"
rrd_version = "0001"
step = 60
last_update = 987064240
ds[InOctets].type = "COUNTER"
ds[InOctets].minimal_heartbeat = 600
ds[InOctets].min = NaN
ds[InOctets].max = NaN
ds[InOctets].last_ds = "318447174"
ds[InOctets].value = 2.9919027356e+04   // not my pb value, see my folowing
fetch
ds[InOctets].unknown_sec = 0
rra[3].cf = "MAX"
rra[3].rows = 4320
rra[3].pdp_per_row = 5
rra[3].xff = 5.0000000000e-01
rra[3].cdp_prep[0].value = NaN
rra[3].cdp_prep[0].unknown_datapoints = 0

my rrdtool fetch:

		IfInOctets
986555100: 1.1968156178e+07
986555400: 7.8210592919e+05
986555700: 6.5298814072e+02


where is my error ?
what sort of operation must i make to obtain correct value ?

regards

Fabrice.
