WPA does not see ETW event data, tracerpt does

由 北城余情 提交于 2019-12-23 18:54:44
问题 I am capturing ADO.Net diagnostics ETW, as described in Data Access Tracing in SQL Server 2008. The setup works, an ETL file is produced and I can see the ADO.Net trace if I use, say, tracerpt: System.Data, TextA, 0, 0, 0, 0, 17, 0, 0x0000000000000000, 0x000007D0, 0x00003A64, 1, , , {00000000-0000-0000-0000-000000000000}, , 131485096603462277, 450, 2400, 2, "enter_01 <prov.DbConnectionHelper.CreateDbCommand|API> 1# " System.Data, TextA, 0, 0, 0, 0, 17, 0, 0x0000000000000000, 0x000007D0,

问题 My symbol resolution on an x64 NGEN .NET 4.0 assembly it not working. Details: I have a .NET 4.0 command line assembly that I am compiling using Visual Studio with an x64 configuration. After I compile, I run NGEN (The 64 bit version) on it. Having failed with XPERF analysing the callstacks (with -stackwalk profile) which won't resolve my symbols. I am now trying Perfmonitor from here: http://bcl.codeplex.com/releases/view/42784 I have done these steps and would have expected the call stacks

问题 I read through the docs and used the commands outlined however for some reason I dont seem to be getting any symbols, just a series of "unknowns" in the function column of the summary table for everything except the topmost set of the app I was trying to debug.... I set the enviromental variable to the microsoft server and the direcories containg the pdb's for the app. I also made sure to select the "Load Symbols" item before bringing up the summary table. Arcording to the info I was reading

What is Hard Faults in XPerf

由 試著忘記壹切 提交于 2019-12-22 09:36:00
问题 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 回答1: 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

How to gather CPU utilization sampling with xperf (Windows Performance Toolkit)

由 陌路散爱 提交于 2019-12-13 09:46:35
问题 I want to analyze performance of long process (6-8 hours). I need information about created/finished processes (with command lines) and CPU utilization. I found, that Windows Performance Analyzer (wpa.exe/xperfview.exe) is great tool for analyzing. I create performance data collector, select provider 'Windows Kernel Trace', keyword 'process' and got information about processes. But I can't find how to collect information about CPU utilization with sampling. I know, that xperf.exe -on Base

Capture callstack and events in Xperf

由 天涯浪子 提交于 2019-12-09 23:44:55
问题 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

xperf can't load my DLL's symbols

由 孤者浪人 提交于 2019-12-09 04:26:28
I'm trying to use xperf to profile my DLL, but it refuses to use my DLL's PDB file. Running xperf on the .etl with -symbols, I get: DBGHELP: mydll- private symbols & lines C:\mydll\debugu\mydll.pdb - unmatched Which leads me to believe it thinks my PDB doesn't match the DLL the application is using. This is wrong; it does match. I've confirmed the path of the DLL the application is linking with using procexp, completely rebuilt the project, and so on. It still thinks it doesn't match. Any ideas on what could be wrong? Try setting a SYSTEM environment variable _NT_SYMBOL_PATH to point to your

Trouble getting xperfview to load symbols for DLL

由 ε祈祈猫儿з 提交于 2019-12-08 03:56:22
问题 I have been fighting tooth and nail with xperf to get symbols for a tool I'm profiling. My code that runs within the tool is split between the .exe and a .dll -- the important stuff to profile being in the .dll. I ran xperf: xperf -on PROC_THREAD+LOADER+INTERRUPT+DPC+PROFILE -stackwalk profile And then I ran my tool for a bit, and then xperf -d profile.etl Then I tried xperfview. I loaded up the profile, toggled "load symbols" on, and opened the summary table. No symbols at all -- literally

Are perfmon performance counters based on the same thing “under the hood” as the ETW events used by xperf?

由 ♀尐吖头ヾ 提交于 2019-12-07 14:39:29
问题 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
