PerformanceCounter Guide: Methods & Examples

PerformanceCounter is a class used for measuring computer performance metrics, assisting developers in monitoring system performance and conducting various performance analysis and optimization operations.

The PerformanceCounter class offers a range of properties and methods for creating and managing performance counters. Here are some commonly used example methods:

1. Create a new instance of a performance counter. You can specify information such as the counter’s name, category, counter type, and more.
2. Create a new PerformanceCounter object that monitors the Processor instance’s % Processor Time for all cores.
3. NextValue: Retrieve the next sampled value of the counter. This method is used to get the current value of the counter and update it on the next call.
4. Obtain the next value and store it as a floating-point number in the variable “value”.
5. RawValue: Obtain or set the original value of the counter. This method can be used to set the initial value of the counter or retrieve the current value of the counter.
6. Set counter’s RawValue to 100 and then access it as an integer stored in the variable value.
7. IncrementBy: 增加计数器的值。这个方法可以用于对计数器的值进行递增操作。
8. Increase the counter by 10.
9. Decrease: Reduce the value of the counter. This method can be used to decrement the value of the counter.
10. Decrease the counter.
11. Reset: Restoring the value of the counter. This method sets the value of the counter back to zero.
12. Reset the counter.

Developers can easily create and manage performance counters to monitor system performance and make necessary optimization operations using the PerformanceCounter class.
