Performance Measurement - Get Average call time per function. Intel Vtune Amplifier
1) You have to run "Advanced Hotspots" analysis configured like shown in your second screen-shot. "Basic Hotspots" will NOT provide you with call count information. Are you sure that you actually have RUN "Advanced Hotspots" analysis? 2) Once you completed "Advanced Hotspots" at least for Amplifier XE 2015 GUI -...
Monitor CPU spikes of any process over X percent for Y seconds
.net,vb.net,performance,cpu,performancecounter
You could try something like the code below. Effectively, check the TotalProcessorTime for each process each time you call CheckCpu() and then subtract this from the previous run and divide by the total time that has elapsed between the two checks. Sub Main() Dim previousCheckTime As New DateTime Dim previousProcessList...
Are any special security rights required to read performance data counters on Windows?
c++,security,winapi,performancecounter
The required privileges are mentioned in the description "About Performance Counters" here: Only the administrator of the computer or users in the Performance Logs User Group can log and view counter data. Users in the Administrator group can log and view counter data only if the tool they use to...
Time running backwards with QueryPerformanceCounter()
c++,timer,embedded,windows-ce,performancecounter
Counter Value: 6536266821 Counter Value: 6536266262 Counter Value: 6536266604 even the third read is smaller than the first! But what is the relevance here? You should read the performance counter frequency using QueryPerformanceFrequency() to investigate what a difference of a few hundred counts actually means. With a frequence in...
Why is the “Process ID” counter in “.NET CLR Memory” category constantly zero?
.net,process,clr,performancecounter,perfmon
As it happens, an instance of this counter will have the value zero until the first garbage collection occurs in the process associated with that instance. This fact is documented in the counter help text associated with the "Process ID" counter: This counter displays the process ID of the CLR...
Passing IPC(Instructions/Cycles) continuously to other function or variable
linux,performance,shell,linux-kernel,performancecounter
Couple of shell syntax issues here. First, retval=... is going to set the retval variable equal to the first part of the string on the right side of the '='. The ampersand will then background the whole thing, essentially throwing that value away. You probably meant to do: retval=`./perf periodic...
System.ComponentModel.Win32Exception : Access is denied
c#,windows,permissions,windows-services,performancecounter
Services typically run as Network Service or Local System, unless you have configured them overwise. It sounds like you haven't changed the service logon user. You can do it from service control manager by right clicking the service and going to the Logon tab. Or you can do it from...
performance monitor - getting current downloaded bytes
I'll answer myself. as OldFart mentioned, by calling new object each time I reset the counter to 0 every time. I managed to handle this by previously creating a list of all instances and iterating them later. Like this: List<PerformanceCounter> instancesList = new List<PerformanceCounter>(); private void InitializeCounter(string[] instances) { foreach(string...
Performance Counter Instance Name vs. Process Name
Seeing that an answer was not forthcoming, I did some more trial and error testing and observed the following behaviour: Regular Processes It appears that, for the first regular process with a given name, the process name matches the instance name. For subsequent processes with the same name, the instance...

C# Instance Name to Use For Network Interface Performance Counter
Here is some sample code how to iterate through the Network Interfaces; PerformanceCounterCategory category = new PerformanceCounterCategory("Network Interface"); String[] instancename = category.GetInstanceNames(); foreach (string name in instancename) { Console.WriteLine(name); } By utilizing the PerformanceCounterCategory, you can now obtain the Instance Names, and then use in your PerformanceCounter(s) using GetInstanceNames....

If you are familiar with the OSI model http://en.wikipedia.org/wiki/OSI_model you see that you try to interact with layer 3 where you should be interacting with layer 7. I your connection with what ever class you are using you are able to measure bytes sent, specially if you are transporting the...
Why can't I iterate over `performance.timing` using Underscore or lodash?
Only thing I can think of is host object weirdness. Object.keys(performance.timing) returns and empty array. Also code behaves differently if it's run on the page vs run in the console.
Visual Basic Performance Counter Doesn't Work
vb.net,visual-studio-2010,performancecounter
I assume you are actually polling the counter? Try something like this: Option Strict On Option Explicit On Option Infer Off Imports System.Diagnostics Public Class Form1 Private myCounter As System.Diagnostics.PerformanceCounter = New System.Diagnostics.PerformanceCounter() Private WithEvents poll As New Timer Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles...

Remote Performance Counters System.InvalidOperationException
c#,.net,performancecounter,system.diagnostics
It seems like reading performance counters over a network is simply not super reliable. I've decided to use the Microsoft Transient Fault Handling library (v 6.0, search topaz on nuget) and implemented a retry strategy. Usually one retry is enough to get a valid answer (no exeception), sometimes it might...
How do I create and use System.Diagnostics.PerformanceData.CounterSet?
.net,powershell,performancecounter
Turns out that this was an (undiagnosed) anomaly with my Powershell session. When I ran this in my Powershell ISE (non-admin) I was getting the following error: > Get-Counter -ListSet MyCategory Get-Counter : Cannot find any performance counter sets on the localhost computer that match the following: MyCategory. At line:1...
C# PerformanceCounter list of possible Parameters?

Those can be obtained from the PerformanceCounterCategory class: PerformanceCounterCategory[] categories = PerformanceCounterCategory.GetCategories(); foreach(var category in categories) { string[] instanceNames = category.GetInstanceNames(); foreach(string instanceName in instanceNames) PerformanceCounter[] counters = category.GetCounters(instanceName); } ...
Why does QueryPerformanceCounter/QueryPerformanceFrequency fail?
Under what circumstances does QueryPerformanceFrequency return FALSE, or QueryPerformanceCounter return zero? This won't occur on any system that runs Windows XP or later. That is correct, perhaps with the slight change in phrasing: This can occur on any system that runs Windows XP or later. There are circumstances where...
Create performance counters on remote server with PowerShell
windows,powershell,performancecounter
There aren't any built-in cmdlets to do that. However, since you have the entire .NET Framework at your disposal, you can use PerformanceCounterCategory.Create to create counter categories. To create them on a remote machine, you would have to enable powershell remoting. An example, which creates a single instance category of...
Why is the graph spiky when using average?
c#,.net,performance,performancecounter,performance-monitor
The problem is, that the AverageTimer32 doesn't show some alltime average value. From the documentation: An average counter that measures the time it takes, on average, to complete a process or operation. Counters of this type display a ratio of the total elapsed time of the sample interval to the...
Taking a computer “performance snapshot”
c#,.net,performance,performancecounter
Your problem with processor time is you are not supposed to use RawValue on it (you really should not use it for working set either). For processor time you must take two samples calling NextValue, One you get a 2nd sample you will have accurate numbers. PerformanceCounterCategory perfCategory = PerformanceCounterCategory.GetCategories().First(c...
PerformanceCounter reporting higher CPU usage than what's observed
c#,cpu-usage,performancecounter
new PerformanceCounter("Processor", ...); You are using the wrong counter if you insist on seeing an exact match with Task Manager or Perfmon. Use "Processor Information" instead of "Processor". The reason these counters show different values is addressed pretty well in this blog post. Which counter is "right" is a...
