xperf

I have recently been becoming acquainted with perfmon and with xperf. Perfmon uses performance counters and xperf uses ETW (event tracing for windows). Perfmon has objects that provide data, whereas xperf uses groups of "providers". As a newbie into this area I am asking whether anyone could tell me whether the performance counters used by perfmon are really based on the same thing under the hood as the ETW events used by xperf and if so, could you make the connection clear. If they aren't based on the same thing, could you explain how they are different? Perf counters and ETW are two

I'm trying to profile a system with XPerf. And see that performance problems occurs when there is activity in HardFaults ! But what I cant figure out and find in google what are these Hard Faults that xperf shows. What are they related to? What do they indicate? Is there any universal remedy for such situations? Hard faults table Indeed. "First of all, a "hard fault" was previously called a "page fault" in earlier versions of Windows. Perhaps page faults were more easily understood from the name, too. A hard fault happens when the address in memory of part of a program is no longer in main

Sorry about the dumb question. I am new to Xperf. I am on 64-bit Windows 8.1 and my application is also x64. I want to capture both the callstacks and my defined events in the application using Xperf. I registered the GUID 35f7872e-9b6d-4a9b-a674-66f1edd66d5c in my application. When I was using: xperf -on PROC_THREAD+LOADER+Base -start UserSession -on 35f7872e-9b6d-4a9b-a674-66f1edd66d5c -BufferSize 1024 -stackwalk profile I can get all the events but no callstack. However if I remove -on 35f7872e-9b6d-4a9b-a674-66f1edd66d5c and the command lines becomes: xperf -on PROC_THREAD+LOADER+Base

I'm trying to add performance counters and custom events to a piece of software, so that I can view these using Windows Performance Toolkit programs such as XPerf and GPUView. I am going to refrain, using all my powers of restraint, from launching into a cathartic rant regarding the state of the documentation for the software and the time I've now wasted trying to tease clues from the web. I'm going to describe how I got to where I am now, just in case this is of use to other lost souls. So far, I've gathered that I have to write an Event manifest for my performance counters and events. You
