    Hi

    Is it possible to monitor CPU Ready Time in perfmon.  If it is what counter would we use?

    Thanks in advance.

    Hi,

    You should be able to do this by selecting the VM Processor object within Windows perfmon.

    Sometimes these counters are missing, if that is the case you should be able to find some threads on how to add them in.

    Thanks for the reply, however there does not seem to be any monitor that relates to the CPU Ready time.   The closest i could find was % processor time

    I doubt it, as CPU ready time is a host level metric. Will be interesting if you find a way :smileyhappy:

    CPU Ready is actually a per VM statistic.  Perfmon counters are available.  Check the performance monitoring guide. http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-monitoring-performance-guide.pdf

    CPU ready is not specifically listed in the VM Processor object, at least not in the 4.1 tools package.

    You have % processor time, effective vm speed, host processor speedk limit, reservation, shares, and cpu stolen time.

    Not saying it isn't a statistic available on a per-VM basis, however it is a metric tracked by the host, not the guest.

    Thanks for the feedback

    Our major issue is that a server could be timing out on certain applications, and when users look at the CPU and Memory in perfmon, everything looks fine and it ends up been the CPU Ready time.

    If we could add a counter to perfmon, it would make troubleshooting issues alot easier.

    Are they looking at the VM Processor and VM Memory objects? As opposed to traditional processor and memory.  That would give a little better view at what the hypervisor is doing.

    Yes they are but there is still nothing that really shows that ready time could be affecting them, unless im missing something?
