[rrd-users] Re: NaN

[Tobias Oetiker]

Today you sent me mail regarding [rrd-users] NaN:

*> Hi All,
*> 
*> When i run the following commands (i've made them a bit more readable but i run it normally without the 'backslashes') the database is filled with NaN as you can see in the rrdtool dump below.
*> 
*> Any ideas about what I may be doing wrong?
*> 
*> Thankz,
*> 
*> Gert-Jan Aalderink
*> 
*> /usr/local/bin/rrdtool create 154.16.1.1_19.rrd \
*>    --start 951814799 --step 300 DS:ifinoctets:COUNTER:300:U:U \ 
*>    DS:ifoutoctets:COUNTER:300:U:U RRA:AVERAGE:0.5:300:24

the the minimal required heartbeat to something like 600 or so ... 

cheers
