I have one VM having 2 CPUs, cpu0 and cpu1. I am able to see the perf data thru VI client for the same VM . I am using below given code for getting real time data. Using Java APIs.
metrics = vmware.getService().queryAvailablePerfMetric(pmRef,vmMor,null,null,new Integer(20));
PerfQuerySpec qSpecObj = new PerfQuerySpec();
PerfQuerySpec qSpec = (PerfQuerySpec)qSpecList.toArray(new PerfQuerySpec[http://qSpecList.size()|http://qSpecList.size()]);
pValues = vmware.getServiceRef().queryPerf(pmRef, qSpec);
but when I parse this pValues set . I am able to get the stats data for cpu0 but not for cpu1.
Is anything wrong with this code ? or Do I need to do something more ? Am I missing anything ?
Same is happening with disk instance . I am not able to get stats data for vmhba1:0:0.
Thanks in Advance.
You can find out more by calling QueryAvailablePerfMetric() method. It should give you an array of PerfMetricId object. From there you can examine in details.

Yes steve. I am using that API only first to get complete metrics available and as is I am setting to perfqueryspec object for each MOR but still I am getting data only for cpu0 not for cpu1. Same is happening with Hosts also like if in a host there are 16 cpu threads I am getting data only for 8 cpu(0-7) instances. So is anything more I am supposed to do ? or I am not able to understand the data which I am getting as result of executing queryPerf() ?
