[rrd-users] Re: adding holt-winters forecasting to existing databases

[Darryl Lewis]

I'm running rrdtool-1.2.4

create users_HW.rrd --step 60 \
                         DS:users:GAUGE:600:U:U \
                         RRA:AVERAGE:0.5:1:1440 \
                         RRA:HWPREDICT:1440:0.1:0.0035:288

When I try creating a HW rrd, I'm getting the following error:

ERROR: can't parse argument 'RRA:HWPREDICT:1440:0.1:0.0035:288'

Anyone got any ideas?

Hi,

'rrdtool fetch' would give you values in
timestamp:<value> form.

So write a small script so that, each line obtained
using 'rrdtool fetch' from the original rrd is
inserted into the new rrd using rrdtool update.

HTH,
Praveen.
