And they're there.

Your DS has a heartbeat of 600 secs. If you update with an interval of
little over 10 minutes, your updates are considered not valid.

Ok this is getting really frustrating, can someone tell me why this
doesn't 
work:

rrdtool create host1users.rrd --step 300 DS:host1users:GAUGE:600:0:50 
RRA:AVERAGE:0.5:1:600 RRA:AVERAGE:0.5:1:600 RRA:MAX:0.5:1:600
RRA:MAX:0.5:1:600

then:

rrdtool update host1users.rrd N:18
rrdtool update host1users.rrd N:20
rrdtool update host1users.rrd N:22
rrdtool update host1users.rrd N:25

do the updates over a period of 10 minutes, yet rrdtool dump always
shows "NaN"

Why??

and yes, I've tried these as well:

rrdtool create host1users.rrd --step 300 DS:host1users:GAUGE:600:0:50 
RRA:AVERAGE:0.5:1:600 RRA:AVERAGE:0.5:1:600 RRA:MAX:0.5:50:600 
RRA:MAX:0.5:50:600
rrdtool create host1users.rrd --step 300 DS:host1users:GAUGE:600:0:50 
RRA:AVERAGE:0.5:50:600 RRA:AVERAGE:0.5:50:600 RRA:MAX:0.5:50:600 
RRA:MAX:0.5:5:600
rrdtool create host1users.rrd --step 300 DS:host1users:GAUGE:600:U:U 
RRA:AVERAGE:0.5:1:600 RRA:AVERAGE:0.5:1:600 RRA:MAX:0.5:1:600
RRA:MAX:0.5:1:600

nothing seems to make any difference, what's going on?
can someone else test this and make sure I'm not just going crazy ? :)

Dan.
