CasCap.Common.Extensions.Diagnostics.HealthChecks

Custom ASP.NET Core health check base classes for monitoring HTTP endpoint availability.

Installation

dotnet add package CasCap.Common.Extensions.Diagnostics.HealthChecks

Target frameworks: netstandard2.0, net8.0, net9.0, net10.0

Usage

Implement IHealthCheckConfig and supply it to a derived check. This ASP.NET Core example registers an HTTP client and exposes the check through the standard health endpoint:

using System.Collections.Generic;
using System.Net.Http;
using CasCap.Common.Diagnostics.HealthChecks;
using CasCap.Common.Diagnostics.HealthChecks.Abstractions;
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSingleton<IHealthCheckConfig>(new EndpointConfig());
builder.Services.AddHttpClient<EndpointHealthCheck>();
builder.Services.AddHealthChecks().AddCheck<EndpointHealthCheck>("upstream");

var app = builder.Build();
app.MapHealthChecks("/healthz");
app.Run();

public sealed record EndpointConfig : IHealthCheckConfig
{
    public string HealthCheckUri { get; init; } = "https://example.com/health";
    public IReadOnlyList<int> HealthCheckExpectedHttpStatusCodes { get; init; } = [200];
}

public sealed class EndpointHealthCheck(
    ILogger<EndpointHealthCheck> logger,
    HttpClient client,
    IHealthCheckConfig config) : HttpEndpointCheckBase(logger, client, config, "Upstream");

Replace the example URI with the caller's endpoint through application configuration. The base class sends a GET and reports healthy only for an expected status; ConnectionActive tracks the last result. Configure timeouts on the injected HttpClient.

Each probe logs only at Debug. When the endpoint becomes inaccessible the check logs one Warning, repeated failures log at Debug with the count, and the next successful probe logs one Information recovery with the failure count. Log messages name the display name, not the URI.

Configuration Examples

The library does not bind a fixed JSON section. Your application supplies IHealthCheckConfig, either directly as above or by binding its own options.

Property Minimal value Customized example
HealthCheckUri Required endpoint URI https://example.com/ready
HealthCheckExpectedHttpStatusCodes [200] [200, 204]

On .NET Standard 2.0, implement both properties. On .NET 8+, the interface supplies [200] when the status list is not overridden.

Kubernetes Probe Tags

KubernetesProbeTypes.GetTags() maps probe flags to ready, live and startup strings for use with health-check registration and endpoint predicates. Tagging a check does not create Kubernetes probes or configure HTTP health endpoints.
