This is a sample code demonstrating how to get the "Bytes Sent/sec" counter of the 3Com network adapter:


System.Diagnostics.PerformanceCounter performanceCounter1;

performanceCounter1 = new System.Diagnostics.PerformanceCounter();

performanceCounter1.CategoryName = "Network Interface";

performanceCounter1.CounterName = "Bytes Sent/sec";

performanceCounter1.InstanceName = "3Com 3C920 Integrated Fast Ethernet

Controller [3C905C-TX Compatible] - Packet Sc" + "heduler Miniport";

performanceCounter1.MachineName = "sha-lion-01";

MessageBox.Show(performanceCounter1.NextValue().ToString());
