performancecounter

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

问题 I am trying to get the % of total CPU usage to a label1.Caption I've searched and found these: didn't work - http://www.vbforums.com/showthread.php?345723-DELPHI-Get-CPU-Usage not what I need - http://delphi.cjcsoft.net/viewthread.php?tid=42837 also found bunch of solutions regarding calculating the Usage per process but that is not what i am looking for , i just want the total CPU usage like this widget : this is what i am working on : I believe there is a simple way like when we get RAM

问题 When viewing the .Net performance counters using the Performance tool I can see the web process performance counters listed (w3wp, w3wp#1): However when I run the following code as Administrator: var instanceNames = new PerformanceCounterCategory(".NET CLR Memory") .GetInstanceNames() .OrderBy(x => x); foreach (var name in instanceNames) { Console.WriteLine(name); } This is the output I see: Notice the w3wp counters are not listed. Does anyone know why this is the case and how I can fix it?

问题 I am trying to access the following counter-path via the cmdlet get-counter in a locale-independent way: \Memory\Pool Nonpaged Bytes I followed the instructions in this thread to archive this. And so I looked up the two IDs for the counter-path in the registry and got \4\58 But unfortunately this path won't work. I always get the error-message The specified performance-indicator could not be found The path from the other thread \238(_Total)\6 works perfectly fine! But for my path I can only

问题 I'm kind of used to the way how C# applications are able to create performance counters - just instantiating new PerformanceCounter object, and using it. I'm now forced to use unmanaged C (C++?), and I'm really unhappy with ease of use of the API and samples provided. My main pain is the need to use lodctr for loading manifest, as is told in MSDN. I wasn't able to find any solution for this. Is there any way how can I use Performance counters without having explicitly loading the manifest, as

问题 I have a mixed set of servers, some running Windows in English, some others running Windows in Italian. Is there a way to read the value of a performance counter without using locale dependent strings? I read on the Zabbix documentation that it should be possible to use a numeric format like \2\6 but it does not work for me, neither in Zabbix nor Powershell. I'd like to monitor the CPU utilization ( \Processore(_Total)\% Tempo processore ). Any suggestion is welcome. 回答1: The solution is

问题 VS 2005, C# 2.0, .NET 2.0/3.0, Win2003 I'm trying to install a set of performance counters for a MultiInstance. I noticed that some system performance counter categories manage to keep a " total " alive even when there are no other instances. ASP.NET Apps 2.0.50727 is an example. So I've been trying to duplicate this. I created the following routine in an Installer class which I then add to a Custom Action in a setup project. public override void Install(System.Collections.IDictionary

问题 All the Intel CPUs in the last decade (at least) include a set of performance monitors that count a variety of events. Do the latest Intel CPUs, Core i3, i5 and i7 (aka Nehalem) provide a mechanism to count Instructions Per Clock (IPC)? If so, how are they used? If this is possible, I'll probably be writing the code for this in Assembly, but Windows or Linux system calls may also come in useful. 回答1: Yes, the Vtune from Intel (linux and windows) can measure IPC. If you want to measure it by

问题 I'm playing around with QueryPerformanceFrequency . It used to return 3.6 Mhz , but it was not enough for what I was trying to do. I've enabled HPET using this command bcdedit /set useplatformclock true . Now it returns 14.3 Mhz . It's great it's more precise... excepted it's not. I quickly realized that I did not get the granularity I expected. If I try to poll QueryPerformanceCounter until it ticks, the smallest increment I can get is 11 , which means 1.27Mhz . If I try to count the number

问题 I'm attempting to use VsPerfCmd.exe to profile branch misprediction and last level cache misses in an instrumented native application. The setup works as it says on the tin, but the results I'm getting don't seem sensible. For instance, a function that always touches a data set of 24MB is reported to only cause ~700 cache misses when being called ~2000 times. Now let me put this into perspective - The function linearly traverses two arrays of 1024*1024 elements of 12-byte elements. For every
