Hi,
could anybody help me with this (see topic)? I'm slowly getting crazy ....
Daily I get input (prices), but at some days I don't get prices (for
example Sundays).
Now, I want to get the average price for every month (30 days) (the average
should ignore the days where I don't get prices).
What I did:
create:
rrdtool create filename.rrd \
>
> > --step '86400' \
>
> > --start '1356998400' \
>
> > 'DS:price:GAUGE:86400:U:U' \
>
> > 'RRA:AVERAGE:0.99:30:2'
>
>
>
fill:
> rrdtool update filename.rrd 1357365600:5 1358229600:4 1359698400:5
> 1359871200:6 1361340000:4
>
and fetch:
jonas@jonas-ThinkPad-T410:/tmp/3$ rrdtool fetch filename.rrd AVERAGE -s
> 1356998400 -e 1361340001
price
> 1358208000: -nan
1360800000: -nan
1363392000: -nan
And the result is NaN for every month. What am I doing wrong?
Thanks!
Cheers, Jonas
