As mentioned before, it doesn't really have anything to do with multicpu.conf nor does multicpu.conf ever reference this file. There is one catch with multicpu.conf however, it is not completely configured out of the box. It is only configured for a single cpu0. Since the multicpu module discovers the number of cpus supported on the box at start up time and creates metrics dynamically for each cpu discovered, there is no way to preconfigure the module. If the box has more than a single cpu, the multicpu.conf file must be modified to expose the additional cpus. The easiest way to tell what additional cpuX metrics are supported is to simply run gmond -m to get a list of all metrics. Any dynamically created metrics will appear in the list. The same concept is also true for the multidisk python module since it also has to discover all of the individual disks on the system and create dynamic metrics at startup time.
