Hi Rob,

I think the following code is what you have suggested:

	RRDs::graph "/tmp/dummy.png",
		    "-s -1$_[1]",
		    "PRINT:mem:MAX: %5.3lf %3bytes",
		    "PRINT:mem:MIN:      %5.1lf %sbytes",
		    "PRINT:mem:AVERAGE:      %5.3lf %sbytes",
		    "PRINT:mem:LAST:     %5.3lf %sbytes",

		    "PRINT:kernel:MAX:             %5.1lf %sbytes",
		    "PRINT:kernel:MIN:      %5.1lf %sbytes",
		    "PRINT:kernel:AVERAGE:      %5.1lf %Sbytes",
		    "PRINT:kernel:LAST:     %5.1lf %Sbytes";

But how to access the result of the 8 PRINT commands and redirect their
values to perl variables?
