[rrd-users] hwpredict question

[John Conner]

According to rrdtool manual, when I have the following RRA, rrdtool should
store 7 days of forecasts,

rrdtool create traffic.rrd -s 300
...blablabla
...blablabla
RRA:HWPREDICT:2016:0.001:0.0035:288

If I understand correct, this means rrdtool will study 7 days of traffic
patterns and give failure alerts beginning from next week, but why on the
third day I begin to get failure alerts? I think at that time, rrdtool even
does not have the traffic pattern for the 3rd day, how can it generates
failures?

Any input is greatly appreciated! Thanks
