[rrd-users] rrdtool update works, but data is never put into rra

[Matthew Sacks]

rrdtool version:
[msacks at tl1rad718 ~]$ /usr/bin/rrdtool
RRDtool 1.2.23  Copyright 1997-2007 by Tobias Oetiker <tobi at oetiker.ch>
              Compiled Jun  7 2007 00:19:10

Please help!:


i have executed the following command:
 /usr/bin/rrdtool update
/usr/local/cacti/cacti-0.8.7b/rra/tl1rap901_cmemds1_10.rrd --template
CMemDS1 1231532052:1736




however, when looking into the rra, all i get are NaN's.
any suggestions on how to fix this?


here is what the file looks like if i remove the NaN's (this message
would be huge if I include them:

/usr/bin/rrdtool dump
/user/local/cacti/cacti-0.8.7b/rra/tl1rap901_cmemds1_10.rrd | grep -v
