Computer Performance Monitoring Tool (written in C#)

After a long long time.. I finally got the time to post a blog (this is due to my very busy schedule). Today I will talked about measuring computer performance remotely using WMI classes

Problem at hand: We have this Pentium III server that chokes from time to time, due to heavy load processes . The server runs several distributed and web applications. To monitor it and prevent possible slowdown I decided to create a tool that will track the server CPU% utilization, Memory Used and Disk Usage levels. The tool will alert user/administrator when one or all of these variables reached pre-defined criteria (ie. CPU% >= 90%).

The Solution: Using the WMI classes, the tool will connect to the remote server and get these informations:CPU, Memory and Disk

using System.Management; //Namespace for to access WMI classes ConnectionOptions options = new ConnectionOptions(); options.Username = strUserName; options.Password = strPassword; mgmtScope = new ManagementScope("\\\\" + strHostName + "\\root\\cimv2",options);

//Get the CPU %

ManagementPath mPath_CPU = new ManagementPath();
mPath_CPU.RelativePath = "Win32_PerfRawData_PerfOS_Processor.Name='0'";
mObject_CPU = new ManagementObject(mgmtScope,mPath_CPU,null);

//Memory Available (in MBytes)
ManagementPath mPath_Mem = new ManagementPath();
mPath_Mem.RelativePath = "Win32_PerfRawData_PerfOS_Memory";
mc = new ManagementClass(mgmtScope,mPath_Mem,null);

// Disk %
mPath_Disk = new ManagementPath();
mPath_Disk.RelativePath = "Win32_PerfRawData_PerfDisk_PhysicalDisk.Name='_total'";
mObject_Disk = new ManagementObject(mgmtScope,mPath_Disk,null);

Here's a screenshot of the final product.



Value-added features are processes list, disk collection and user sessions. This tool was written in C# (Visual Studio .NET). Take note that WMI classes is only available in Windows NT/XP based systems.
