Hidden vCenter Debugging Performance Metrics

08.04.2011 by William Lam // 1 Comment

While extracting the new performance metrics in vSphere 5 for a blog post, I came across a metric type that I had never noticed before, vcDebugInfo. These performance metrics seems to deal with some of the internal performance/counters in vCenter such as lock statistics, MoRef (Managed Object Reference) counts, etc. Majority of these metrics are available in either collection level 1 or 4 which is the highest level containing all statistics. VMware's best practice is to only enable collection level 1 or 2, 3 and 4 should only be enabled under VMware supervision for debugging purposes which is most likely when some of these stats may come in handy. So be warn, these are probably not supported by VMware

I found it interesting that these metrics are hidden from the vSphere Client UI, but they can easily be extracted when going through the vSphere API. It is just amazing on all the goodies you can find when going through the APIs 🙂

    It is so amazing to read such beautiful article. Thanks for that.
    I just wanted to know how if I can collect these counters using vSphere infrastructure API?
    If yes, then how? Please tell.
    Thanks,
