performancecounter

问题 I'm trying to display the received bytes per second and have them displayed in the console once a second. The I am presented with a Invalid Operation Exception once it reaches .nextvalue. PerformanceCounter NetworkDownSpeed = new PerformanceCounter("Network Interface", "Bytes Received/sec"); float CurrentNetworkDownSpeed = (int)NetworkDownSpeed.NextValue(); while (true) { Console.WriteLine("Current Network Download Speed: {0}MB", CurrentNetworkDownSpeed); Thread.Sleep(1000); } 回答1: Sorry for

问题 I have an assembly which monitors the performance statistics of a number of our micro services running on a machine. The code is using performance counters to obtain and publish the data as below: _counters = new Dictionary<string, PerformanceCounter> { ["System Memory Available Bytes"] = new PerformanceCounter { CategoryName = "Memory", CounterName = "Available Bytes", ReadOnly = true }, ["System CPU Usage %"] = new PerformanceCounter { CategoryName = "Processor", CounterName = "% Processor

问题 This is the code: private static void CreateCounter() { if (PerformanceCounterCategory.Exists("DemoCategory")) PerformanceCounterCategory.Delete("DemoCategory"); CounterCreationDataCollection ccdArray = new CounterCreationDataCollection(); CounterCreationData ccd = new CounterCreationData(); ccd.CounterName = "RequestsPerSecond"; ccd.CounterType = PerformanceCounterType.NumberOfItems32; ccd.CounterHelp = "Requests per second"; ccdArray.Add(ccd); PerformanceCounterCategory.Create("DemoCategory

问题 I need to get performance counters from the network card. To make things easy, the user selects the needed adapter by typing an index number in a console application. This is the code that gets the user input and creates performance counter instance var connectionNames = NetworkCardLocator.GetConnectedCardNames().ToArray(); log.Debug("Please select one of the available connections"); log.Debug("--"); for (int i = 0; i < connectionNames.Count(); i++) { log.Debug(i + ". " + connectionNames[i]);

问题 I'm working on a server that reads the '% CPU' and 'Available memory' from PerformanceCounters. It works good on my development machine. But on actual servers, it is really slow to read from these two PerformanceCounters. at least at the first two read operations. It can take up to 4-6 minutes performing the code below: Stopwatch watch = new Stopwatch(); Log.Instance.Debug("Going to initialize Diagnostic's PerformanceCounters"); watch.Start(); m_CPUPerformanceCounter = new PerformanceCounter(

问题 I'm creating a C# WinForm Application which will display Network Activity (Bytes Received / Bytes Sent) for a given Process (For Example: Process name 's chrome.exe ) and Speed in Megabyte/s generated by the Process. My application uses Performance Counter Class to get the Process activities like IO Read Bytes/sec for received bytes and IO Writes Bytes/sec for sent bytes. But, it's giving me 0 Bytes as a result, which's very weird because chrome.exe is running and its definitely using some

问题 In developing a performance monitoring console app, what is passed into the getcategories method?: PerformanceCounter[] pcArr = pc.GetCounters(string instance); When using the no param overload, a runtime exception is thrown: Counter is not single instance, an instance name needs to be specified. Also, how do you decide between a static utility method or an extension method? For example, I may use a certain utility method quite frequently but then it would be best to add that as an extension

问题 I'm currently trying to build a simple component which should monitor, if the user opens a window with a specific URL (IE only). So I wrote this component and everything works fine, so I integrated it with the application, where it was needed. The problem is, in this application PerformanceCounters are used, and these seem to disturb the behaviour of the InternetExplorer automation object. So I wrote this little sample to demonstrate the problem: using System; using System.Collections.Generic

问题 Years ago I wrote some code to "publish" data for perfmon to consume. Using those counters is pretty well documented, but I found it challenging to find (at the time) good documentation and sample code to publish the data for perfmon. Does anyone know where I can get this documentation? I also seem to recall some class wrappers, but I may be mistaken. EDIT: I did find this, and I will keep looking for "custom application performance counters". 回答1: You're bringing back old memories! From 1998

问题 I'm trying to add some system monitoring functions to a WPF app I am working on and I would like to add a bandwidth use monitor. Right now I have a CPU and a RAM counter working but I can't figure out what to use for the Performance Counter instance name (sorry if that isn't the correct term). This is what I'm using so far: PerformanceCounter cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total"); PerformanceCounter ramCounter = new PerformanceCounter("Memory",
