Read CPU and Memory usage in ASP.Net using C# and VB.Net

Hi Waghmare,

Refer below example to get CPU and Memory utilisation.

HTML

<asp:ScriptManager runat="server" />
<asp:UpdatePanel runat="server">
    <ContentTemplate>
        <asp:Label ID="lblCPU" runat="server" /><br />
        <asp:Label ID="lblRam" runat="server" />
        <asp:Timer runat="server" OnTick="OnTick" Interval="1000"></asp:Timer>
    </ContentTemplate>
</asp:UpdatePanel>

protected static PerformanceCounter CPUCounter;
protected static PerformanceCounter memoryCounter;

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        CPUCounter = new PerformanceCounter();
        CPUCounter.CategoryName = "Processor";
        CPUCounter.CounterName = "% Processor Time";
        CPUCounter.InstanceName = "_Total";

        memoryCounter = new PerformanceCounter();
        memoryCounter.CategoryName = "Memory";
        memoryCounter.CounterName = "Available MBytes";
    }
}

protected void OnTick(object sender, EventArgs e)
{
    // Check the if condition for value greater than 90.
    lblCPU.Text = GetCpuUsage().ToString("N2") + "%";
    lblRam.Text = GetMemory() + "MB";
}

public float GetCpuUsage()
{
    return CPUCounter.NextValue();
}

public float GetMemory()
{
    return memoryCounter.NextValue();
}
