Get current CPU, RAM and Disk drive usage in C#

Here is a solution which will output disk usage, the total disk percent being used at the time that Timer99 is polled:

 using System; using System.Diagnostics; using System.Windows; namespace diskpercent { public partial class MainWindow : Window { DispatcherTimer Timer99 = new DispatcherTimer(); public MainWindow() { InitializeComponent(); Timer99.Tick += Timer99_Tick; // don't freeze the ui Timer99.Interval = new TimeSpan(0, 0, 0, 0, 1024); Timer99.IsEnabled = true; } public PerformanceCounter myCounter = new PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total"); public Int32 j = 0; public void Timer99_Tick(System.Object sender, System.EventArgs e) { //Console.Clear(); j = Convert.ToInt32(myCounter.NextValue()); //Console.WriteLine(j); textblock1.Text = j.ToString(); } } } 

and here is a list of common performance counters:

 PerformanceCounter("Processor", "% Processor Time", "_Total"); PerformanceCounter("Processor", "% Privileged Time", "_Total"); PerformanceCounter("Processor", "% Interrupt Time", "_Total"); PerformanceCounter("Processor", "% DPC Time", "_Total"); PerformanceCounter("Memory", "Available MBytes", null); PerformanceCounter("Memory", "Committed Bytes", null); PerformanceCounter("Memory", "Commit Limit", null); PerformanceCounter("Memory", "% Committed Bytes In Use", null); PerformanceCounter("Memory", "Pool Paged Bytes", null); PerformanceCounter("Memory", "Pool Nonpaged Bytes", null); PerformanceCounter("Memory", "Cache Bytes", null); PerformanceCounter("Paging File", "% Usage", "_Total"); PerformanceCounter("PhysicalDisk", "Avg. Disk Queue Length", "_Total"); PerformanceCounter("PhysicalDisk", "Disk Read Bytes/sec", "_Total"); PerformanceCounter("PhysicalDisk", "Disk Write Bytes/sec", "_Total"); PerformanceCounter("PhysicalDisk", "Avg. Disk sec/Read", "_Total"); PerformanceCounter("PhysicalDisk", "Avg. Disk sec/Write", "_Total"); PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total"); PerformanceCounter("Process", "Handle Count", "_Total"); PerformanceCounter("Process", "Thread Count", "_Total"); PerformanceCounter("System", "Context Switches/sec", null); PerformanceCounter("System", "System Calls/sec", null); PerformanceCounter("System", "Processor Queue Length", null); 

Drives

static void Main(string[] args) { var drives = DriveInfo.GetDrives(); foreach (DriveInfo info in drives) { Console.WriteLine("Name: {0}\nSize: {1}\nDrive Format: {2}", info.Name, info.TotalSize, info.DriveFormat); } Console.ReadLine(); } 

There is a NuGet package called hardware.Info by Jinjinov See https://github.com/Jinjinov/Hardware.Info for details.

Code sample:

hardwareInfo.RefreshAll(); //Memory Console.WriteLine(hardwareInfo.MemoryStatus); //CPU foreach (var cpu in hardwareInfo.CpuList) { Console.WriteLine(cpu); foreach (var cpuCore in cpu.CpuCoreList) Console.WriteLine(cpuCore); } //Drives foreach (var drive in hardwareInfo.DriveList) { Console.WriteLine(drive); foreach (var partition in drive.PartitionList) { Console.WriteLine(partition); foreach (var volume in partition.VolumeList) Console.WriteLine(volume); } }
