[hobbit] Graphing help with multiple physical & logical CPUS

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.

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"

Hi all,

I have a script that returns data from a host on the utilization of physical and logical CPUS. The data is returned as an NCV like below:

PCPU0 : 5.44 PCPU1 : 0.10 Physical CPU 0 utilization is 5.44% Physical CPU 1 utilization is 0.10%

In my hobbitserver.cfg file I've added "pcpu=ncv" to the TEST2RRD line and my ncv line should handled up to 8 CPUS NCV_pcpu="PCPU0:GAUGE,PCPU1:GAUGE,PCPU2:GAUGE,PCPU3:GAUGE,PCPU4:GAUGE,PC PU5:GAUGE,PCPU6:GAUGE,PCPU7:GAUGE"

I didn't add this to the GRAPHS line because I'm stuck at the RRD defs part in hobbitgraph.cfg. I don't want a separate RRD def for each physcial CPU, but I do want both (or 8) CPUS to show up on the graph. The same for the logical CPUS.

Any ideas??
