Ok, that looks good.

This might be stupid, but according to this:

http://oss.oetiker.ch/rrdtool/tut/cdeftutorial.en.html

Your DEF lines should be of the format:

DEF:var_name_1=some.rrd:ds_name:CF

But in your case you have:


DEF:serverhttpbitsin=squid.rrd:IN:AVERAGE
DEF:serverhttpbitsout=squid.rrd:OUT:AVERAGE
DEF:numberofclients=squidclients.rrd:clients:AVERAGE

Where you seem to have an odd $ds_name

Where did IN, OUT, and clients come from? Your rrds says your ds names
are numberofclients, serverhttpbitsin, serverhttpbitsout.

It seems this is your problem. Forgive me if it's not, I've only
recently gained a rudimentary understanding of how CDEFs work, their
complexity has overwhelmed me far too long than I care to admit.

Does your rrd have any data in it? (rrdtool dump foo.rrd)
