[rrd-users] Re: updates return 'nan'

[Serge Maandag]

Just a wild guess: should it be a gauge in stead of a counter?
You do know the difference between those two?

Serge.

i have just started experimenting with rrd using tghe cacti frontend.

I have create an rra like so:

/usr/bin/rrdtool create \
/home/matthewh/www/dev/html/cacti-0.6.8a/rra/email_esmtp_in.rrd \
--step 300 \
DS:email_esmtp_in:COUNTER:600:0:50000 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

and attempt to update it like so with my own perl script (below should
all
be on one line):

/usr/bin/rrdtool update /home/matthewh/www/dev/html/cacti-0.6.8a\
/rra/email_esmtp_out.rrd --template email_esmtp_out N:`perl\
/home/matthewh/www/dev/html/cacti-0.6.8a/scripts/mail.pl esmtp out`

this perl script just outputs my sendmail mail stats (script attached).

why, when i update and then fetch do my results come out with either
'nan'
or '00000000e+00' etc?

and my graphs are empty.=20

sorry if i havn't explained this very well, please say if you need
anything
cleared up.

thanks
