I want to get the overall total CPU usage for an application in C#. I\'ve found many ways to dig into the properties of processes, but I only want the CPU usage of the proce
It's OK, I got it! Thanks for your help!
Here is the code to do it:
private void button1_Click(object sender, EventArgs e)
{
selectedServer = "JS000943";
listBox1.Items.Add(GetProcessorIdleTime(selectedServer).ToString());
}
private static int GetProcessorIdleTime(string selectedServer)
{
try
{
var searcher = new
ManagementObjectSearcher
(@"\\"+ selectedServer +@"\root\CIMV2",
"SELECT * FROM Win32_PerfFormattedData_PerfOS_Processor WHERE Name=\"_Total\"");
ManagementObjectCollection collection = searcher.Get();
ManagementObject queryObj = collection.Cast().First();
return Convert.ToInt32(queryObj["PercentIdleTime"]);
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
return -1;
}
