[rrd-users] Optimize RRD update

[Gwenael Lahay]

Hello,

I have two simple questions.
Is it possible to initialize a rrd file with zero values instead of NaN
values ?
More over, is it possible to replace (by default) NaN values with zero for
the period you don't update a rrd.

In fact, i need to optimize a perl script which take a lot of time to update
all the rrd file (especially when there is no data and that i need top
update all the files with zero).
If i could use zero instead of NaN, it will allow me to only update the rdd
files with data. It will take less time.

Thank you

For information, i use this parameters :

RRA:AVERAGE:0:1:4320

RRA:AVERAGE:0.8:5:2016

RRA:AVERAGE:0.94:15:2976
with :

DS:${name}:${type}:300:0:U
