C#: How do you implement health checks in ASP.NET Core?

1builder.Services.AddHealthChecks()
2    .AddSqlServer(connectionString, name: "sql")
3    .AddRedis(redisConnection, name: "redis")
4    .AddCheck<CustomHealthCheck>("custom");

1public class CustomHealthCheck : IHealthCheck
2{
3    public async Task<HealthCheckResult> CheckHealthAsync(
4        HealthCheckContext context,
5        CancellationToken ct = default)
6    {
7        try
8        {
9            // Check something
10            return HealthCheckResult.Healthy("OK");
11        }
12        catch (Exception ex)
13        {
14            return HealthCheckResult.Unhealthy(ex.Message);
15        }
16    }
17}

1app.MapHealthChecks("/health");
2app.MapHealthChecks("/health/ready", new HealthCheckOptions
3{
4    Predicate = check => check.Tags.Contains("ready")
5});
