Hi Folkert, try some examples from the tutorial to see that your rrdtool setup is actually working ...
I can't see from your post why you should be getting nan values ... if you create a little script with create, update, dump you could run it on an other box to see if something is odd locally ... you caoul also post your script for others to try ... cheers tobi Saturday Folkert van Heusden wrote: > No-one has an idea how to fix these NaN problems? > > On Tue, Jan 12, 2010 at 11:44:49PM +0100, Folkert van Heusden wrote: > > A couple of inserts: > > > > mauer:/usr/local/nagios.check_commands# grep > > /usr/local/nagios.check_commands/var/weerstationserver/HTTP/time.rrd > > /tmp/rrd.log > > /usr/bin/rrdtool update > > /usr/local/nagios.check_commands/var/weerstationserver/HTTP/time.rrd > > 1263335162:0.005438 > > /usr/bin/rrdtool update > > /usr/local/nagios.check_commands/var/weerstationserver/HTTP/time.rrd > > 1263335462:0.002476 > > /usr/bin/rrdtool update > > /usr/local/nagios.check_commands/var/weerstationserver/HTTP/time.rrd > > 1263335762:0.002664 > > /usr/bin/rrdtool update > > /usr/local/nagios.check_commands/var/weerstationserver/HTTP/time.rrd > > 1263336062:0.003119 > > > > On Tue, Jan 12, 2010 at 10:19:33PM +0100, Folkert van Heusden wrote: > > > Hi, > > > > > > I create my .rrd-files like this: > > > > > > rrdtool create file.rrd --step 300 \ > > > DS:values:GAUGE:900:U:U \ > > > RRA:AVERAGE:0.5:1:2016 \ > > > RRA:MIN:0.5:1:2016 \ > > > RRA:MAX:0.5:1:2016 \ > > > RRA:AVERAGE:0.5:12:744 \ > > > RRA:MIN:0.5:12:672 \ > > > RRA:MAX:0.5:12:672 \ > > > RRA:AVERAGE:0.5:288:730 \ > > > RRA:MIN:0.5:288:730 \ > > > RRA:MAX:0.5:288:730 \ > > > > > > Then using this: > > > rrdtool update file.rrd N:0.32 > > > I add data to it. > > > This adding data is done multiple times in a 300 second interval and > > > should be averaged.
