Hello,
I want to create bandwidth graph with additional horizontal line, which
presents Max possible speed. RRD files are from MRTG.
I tried this in my PERL script, but without success:
($maxbytes is previously computed value from more RRD files.)
------------
push @args, "CDEF:maxbw=${maxbytes},8,*";
push @args, "LINE1:maxbw#000000:Max speed ${maxbytes}\\l";
------------
I get this error: rpn expressions without variables are not supported
I use rrdtool-1.0.48.
Thanks,
Pavel Ruzicka
