[hobbit] Graphing help with multiple physical & logical CPUS

[shea_greg at emc.com]

Hi Thomas,
 
Thanks for the update, the NCV line will be so much easier to configure using the wildcard.
I've tried a couple of different things for the hobbitgraph.cfg file so that I don't have to include
an entry for each CPU (see below), but I was unsuccessful.  For a 2 Physical CPU box this
isn't so bad and with hyper-threading this would give me 4 logical CPUs.  Now it starts to
get a little messy.  I was hoping there was a way to either use wildcards or a regex in the
DEF and LINE2 lines.  Sun's T2000 will have a 32 logical CPUs (if I read that right).
 
So, that's my true dilemna, I guess I was to vague before.
 
Thanks

Try to look at this howto Henrik did with 2 datasets

http://www.hswn.dk/~henrik/howtograph.txt

and maybe change the line ncv_pcpu line to

NCV_pcpu="*:GAUGE"
