What is performance counter in .NET?

The Performance Counter is a Windows feature that allows you to record and publish system and application performance metrics.

Processes, threads, events, mutexes, and semaphores, as well as features of your own running programs, may all be monitored and analyzed using performance counters. They may assist you in identifying bottlenecks in your system and application, as well as fine-tuning system and application performance.

With a set of easy-to-use types, the.NET Framework supports performance counters. The Common Language Runtime (CLR) also provides its own collection of preconfigured counters.

What is performance counter in .NET?

A performance counter is a feature that measures your system’s or application’s performance. Metrics such as the number of active threads in a process or the value of elapsed time spent executing instructions by threads in a process are typical examples.

Categories are used to organize and group performance counters. The processor category, for example, contains all counters related to the processor’s operation, such as processor time, idle time, interrupt time, and so on.

Windows includes a number of predefined performance counters that can be obtained programmatically or viewed in the Performance Monitor. These counters are used to keep track of how much operating system’s resources are being used.

The CLR offers its own set of performance statistics in the.NET world. From exception handling to security checks, these cover every area of CLR functioning.

.NET CLR Performance Counters

To help you monitor and improve your application’s performance, the.NET Common Language Runtime offers nine performance counter categories. A list of these categories, along with a brief description, can be found in the table below.

There are far too many performance counters linked with these categories to list them all here. You may get more information about performance counters in the.NET Framework General Reference.

Other performance counter categories that aren’t listed in the previous table or in the.NET Framework documentation may be installed on your machine (my installation also includes a Data category for monitoring SQL Server connections.)

ASP.NET exposes its own set of performance counters for people working with Web applications. See “Performance Counters for ASP.NET” in the.NET Framework Developer’s Guide for more details.

Performance Counters in the .NET framework

Following are the different performance counters in the .NET framework:

Exception performance counter

Interop performance counter

JIT performance counter

Loading performance counter

Locks and Threads performance counter

Memory performance counter

Networking performance counter

Security performance counter

Conclusion

We constantly evaluate the performance of our code (applications, services, drivers, and so on) in a testing environment. Then we’ll be able to diagnose and fix problems in the future. We may publish, capture, and analyze the performance statistics of running code using performance counters. There are a lot of counters in each category some of which were mentioned in this post.
