[rrd-users] can't sanity-check rrdtool with sample data ...please help

[Erik de Mare]

Hi,

RRDtool uses when updating a timestamp, I think calculated the following way:
<timestamp> - <timastamp> % <stepsize>

when you update you are inserting data at each day at 8:00.
try updateing it at 0:00 (what rrdtool fetch prints, 1141257600 = Thu, 02 Mar 2006 00:00:00 GMT)

rrdtool update hits.rrd 1141257600:1 1141344000:10
 1141430400:10 1141516800:12 1141603200:12
 1141689600:12

rrdtool fetch hits.rrd MAX --start 1141200000 --end 1141718400
