Entity Framework Core (EF Core) Health Checks
· 1 min read
ASP.NET Core allows us to use health checks to monitor the health of our application. This is useful for monitoring the health of our database, cache, and other services.
Adding a health check for an Entity Framework Core database is not immediately apparent, but is quite simple.
Lets first add the Microsoft.Extensions.Diagnostics.HealthChecks.EntityFrameworkCore package to our project.
I discovered this package by reading the ASP.NET Core source code on GitHub.
Now, where we configure our services, we can add a health check for our database:
e.g. Program.cs
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddHealthChecks().AddDbContextCheck<ApplicationDbContext>();
...Easy as that! The health check will call DatabaseFacade.CanConnectAsync() to check the health of the database.
