How to get the current CPU/RAM/Disk usage in a C# web application using .NET CORE?

Question

I am currently looking for a way to get the current CPU/RAM/Disk usage in a C# web application using .NET CORE.

For CPU and ram usage, I use PerformanceCounter Class

Answer 1

For Windows i'm using this

var   memorielines= GetWmicOutput("OS get FreePhysicalMemory,TotalVisibleMemorySize /Value").Split("\n");

        var freeMemory= memorielines[0].Split("=", StringSplitOptions.RemoveEmptyEntries)[1];
        var totalMemory = memorielines[1].Split("=", StringSplitOptions.RemoveEmptyEntries)[1];


        var cpuLines = GetWmicOutput("CPU get Name,LoadPercentage /Value").Split("\n");


        var CpuUse = cpuLines[0].Split("=", StringSplitOptions.RemoveEmptyEntries)[1];
        var CpuName = cpuLines[1].Split("=", StringSplitOptions.RemoveEmptyEntries)[1];



    private string GetWmicOutput(string query, bool redirectStandardOutput = true)
    {
        var info = new ProcessStartInfo("wmic");
        info.Arguments = query;
        info.RedirectStandardOutput = redirectStandardOutput;
        var output = "";
        using (var process = Process.Start(info))
        {
            output = process.StandardOutput.ReadToEnd();
        }
        return output.Trim();
    }

For the disk infos you can use this query :

LOGICALDISK get Caption,DeviceID,FileSystem,FreeSpace,Size /Value

if you want a better output formatting give a look to this article : https://www.petri.com/command-line-wmi-part-3
