[rrd-users] rrdcgi and SETVAR

Mon Oct 12 11:33:43 CEST 2009

Hi there,
I've done the following simple rrdcgi-script:

--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------

#!/opt/rrdtool/bin/rrdcgi
<HTML>
<BODY>
<RRD::GRAPH
  ip.png
  --imginfo '<IMG SRC=%s WIDTH=%lu HEIGHT=%lu >'

  DEF:ip=ip.rrd:ip:LAST
  AREA:ip#003366:IP
>
</BODY>
</HTML>

--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------

This works so far.
But if I do this:

--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------

#!/opt/rrdtool/bin/rrdcgi
<HTML>
<BODY>
<RRD::SETVAR bla "DEF:ip=ip.rrd:ip:LAST AREA:ip#003366:IP">
<RRD::GRAPH
  ip.png
  --imginfo '<IMG SRC=%s WIDTH=%lu HEIGHT=%lu >'

  <RRD::GETVAR bla>
>
</BODY>
</HTML>

--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------

I get the error:
[ERROR: Cannot parse CF in 'DEF:weltv4=ip.rrd:ip:LAST AREA:ip#003366:IP']

All I want to do is to put

  DEF:ip=ip.rrd:ip:LAST
  AREA:ip#003366:IP

in a variable und read it.

Is this possible (rrdtool version is 1.2.30)?
