http://bugzilla.ganglia.info/cgi-bin/bugzilla/show_bug.cgi?id=84 I think that the fix for this bug should actually include adding 2 more metrics, as the problem as stated isn't really that ganglia isn't reporting the right count of CPUs, but that there is no way to know if it is virtual or real CPUs for inventory and in some sort also scheduling reasons. This way "cpu_num" could be kept as the number of available CPUs, as is implicitly described to do in the current documentation for this metric and will have "cpu_cores" and "cpu_sockets" as the number of available cores or available sockets. of course for HPC, the number of "effective" CPUs is a function of all those 3 and the type of code that is being run, so we should leave up to the end users to figure that out while giving them all the information they need for that. the advantages of doing it this way, are that the code is greatly simplified, all possible use cases are covered and the metric is kept backward compatible. comments, anyone? Carlo
