    Looks like I'm the only one who likes pure xperf commandline. I want to control of what I want to trace. Even PerfView enables so many Providers (JS, "Metro" UI Events) that I don't care.

    @MagicAndre1981: I just came to the situation that I am seeing some warnings in SCCM related to the fragmentation of my W2K12 Domain Controllers disks. They all need a file defragmentation (-d) since they have file level fragmentation around 37% and 40% in their logical disks.

    I understand the cost of doing this in DCs, specifically in normal work hours. We will need to schedule this during off hours.

    @MagicAndre1981: For what it is worth, While the default is designed to get the common case, PerfView gives you easy, complete control.   In particular

    PerfView /kernelEvent=none /clrEvents=none /providers=YOUR_PROVIDERS collect

    Will only enable YOUR_PROVIDERS.  There is a shortcut for that

    PerfView /onlyProviders=YOUR_PROVIDERS

    However the first form is nicer if you do want some of the kernel events or CLR events.   The later form is great if you just want to turn on your specific EventSource.
