Hi Arnau,
not completely :-) I actually want to extract the data from the RRD files
and combine them into one, adding up the vaules. Good thing, I found out
about "rrdtool xport". I does what I want on the extracting. Now I just
need to do the summing up.
Cheers
Martin

Another alternative is to use CSV or JSON export from the Web Ui eg

It will eg export all values from aggregate graphs as well so you can do the

Hi Vladimir,
thanks. That is also an option. What I came up with is the following RRD
magic. Combines 3 metrics metrics from 4 filesystems, removes the NaNs and
computes the percentage used accurately:
rrdtool xport --start now-366d --end now-1d \
DEF:t000=vault_000_total.rrd:sum:AVERAGE \
DEF
