Monitor Application Performance in .NET

Monitoring application performance in .NET is essential to ensure that your system is running efficiently and to quickly identify and resolve performance issues. Various tools and techniques are available to track performance, including built-in .NET capabilities, third-party services, and custom logging approaches.

Below are some of the key strategies to monitor application performance in .NET:

1. Use Application Insights (Azure Monitor)

Azure Application Insights is a powerful, cloud-based monitoring tool that provides detailed telemetry data for .NET applications. It tracks metrics like request performance, dependency tracking, exceptions, and custom events.

Steps to Set Up Application Insights:

Install the Microsoft.ApplicationInsights.AspNetCore NuGet package:

dotnet add package Microsoft.ApplicationInsights.AspNetCore

Add Application Insights to your application in Program.cs:

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddApplicationInsightsTelemetry(builder.Configuration["ApplicationInsights:InstrumentationKey"]);

var app = builder.Build();
