[rrd-users] Newbie: RRD:CV variables

Thu Jan 24 18:04:21 MET 2002

This might just be a silly question, but please bare with me.
Based on example 2 in the rrdcgi man page. How do you define, or how does rrdcgi
know what variables will be subtituted in those tags.

I've also read somewhere that a prior cgi would define the variables in its url.
Something to the effect of test.cgi?rwandal
If that is one option, how would rrdcgi parse the url to use it's variables.

What are the options to define the variables?

Notice the H1 tag with <RRD::CV name> in my example below. I would like the name
to equal rwandal

Using my past example:

#!/usr/bin/rrdcgi

<HTML>
 <HEAD><TITLE>RRDCGI Demo</TITLE></HEAD>
 <BODY>
 <H1>RRDCGI Example Page for <RRD::CV name></H1>
 <P>
 <RRD::GRAPH ../images/test.gif --imginfo '<IMG SRC="/web/images/%s" WIDTH="%lu"
HEIGHT="%lu" >' -t
RWANDAL01_E0 -v bps
DEF:inoctets=rwandal.rrd:input:AVERAGE DEF:outoctets=rwandal.rrd:output:AVERAGE
CDEF:inbps=inoctets,8,* CDEF:outbps=outoctets,8,* A$
LINE1:outbps#0000FF:"Out traffic">
 </P>
 </BODY>
 </HTML>

Thanks in advance!
