[rrd-users] php rrdtool

[Ben Cole]

Hi im using rrdtool via the php module for it, cant seem to find any online
documentation.

Im wondering if i can use rrdtool_fetch to return just the data from one
dataset? im recording data in and data out, and i want the sum over a given
time period but fetch seems to return data from both sets.

Thanks for any help
