Monitoring Performance Thresholds

Windows performance counters allow your applications and components to publish, capture, and analyze the performance data that applications, services, and drivers provide. You can use this information to determine system bottlenecks and fine-tune system and application performance. For example, you might use a performance counter to track the amount of time required to process an order or query a database, or you might monitor the size of a message queue and write code that performs a specific action whenever the queue reaches a preset limit.

Using the PerformanceCounter component and language features in Visual Studio .NET and the Microsoft .NET Framework SDK, you can easily connect to performance counters on both local and remote computers and retrieve values from these counters. You can also write values to existing custom counters (those created with .NET) on the local computer and create your own custom counters on computers that have Windows installed.
