[rrd-users] Creating RRD/RRA

[Mike M]

Hello,

Okay, I know this is going to be a stupid newbie question, but I'd
like to create an rrd that gets populated every hour with a document
count for two different sites.  This number can either increase or
decrease, depending on the number of documents being indexed at a
given time.  I'd like to roll the information up on a daily, monthly,
and yearly basis.

Here's the command I used to initially create the rrd:

$ rrdtool create testdb.rrd \
        DS:webdocs:GAUGE:3600:0:1000000000 \
        DS:intdocs:GAUGE:3600:0:1000000000 \
        RRA:AVERAGE:0.5:1:9600 \ 
        RRA:AVERAGE:0.5:24:9600 \ 
        RRA:AVERAGE:0.5:720:6000

Is this correct?  I haven't had any luck generating graphs after
populating the rrd with:

$  rrdtool update N:876123:987123

I'm sure this is simple for someone out there; although I've read a
load of tutorials, the syntax and usage of rrdtool is just confusing
me right now... :(

Thanks in advance for your help.

Mike
