I'm using
RRDtool 1.3.1 Copyright 1997-2008 by Tobias Oetiker <t...@oetiker.ch>

ii rrdtool 1.3.1-4 Time-series data
storage and display system (programs)
now, for some extra news.
I followed a tutorial at:
http://oss.oetiker.ch/rrdtool/tut/rrdtutorial.en.html
and it worked like a charm *but* if I added entries with timestamps
out of step (e.g., jumping forward 800 instead of 300 as in the
tutorial), I get the RRA full of NaNs. I think that's what broke my
ganglia install here. Folkert's example doesn't work neither on
Squeeze. And my use case
rrdtool create test.rrd \
--start 920804400 \
DS:speed:COUNTER:600:U:U \
RRA:AVERAGE:0.5:1:24 \
RRA:AVERAGE:0.5:6:10
rrdtool update test.rrd 920804700:12345 920805000:12357 920805300:12363
rrdtool update test.rrd 920805600:12363 920805900:12363 920806200:12373
rrdtool update test.rrd 920806500:12383 920806800:12393 920807100:12399
rrdtool update test.rrd 920807400:12405 920807700:12411 920808000:12415
rrdtool update test.rrd 920808300:12420 920808600:12422 920808900:12423
and then doing
rrdtool update 920809900:12423
also doesn't work on a Lenny 32 bit chroot.
I start to think I have ganglia misconfigured and this is just the way
rrdtool is supposed to work.
