XperienceCommunity.AspNetCore.HealthChecks

This project is a NuGet package specifically designed to integrate Kentico Health Checks into applications using the Microsoft.AspNetCore.Health framework. It provides a set of custom health checks that monitor various aspects of a Kentico application, ensuring its optimal performance and stability.

The health checks included in this package cover a wide range of Kentico functionalities, from site configuration and event logs to web farm and search tasks. By leveraging the Microsoft.AspNetCore.Health framework, these health checks can be easily added to any ASP.NET Core application, providing developers with immediate insights into the health of their Kentico applications.

This package is an essential tool for any developer working with Kentico in an ASP.NET Core environment, simplifying the process of monitoring and maintaining the health of their applications.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

1. .NET 6/.NET 8
2. Kentico Xperience 13 Application.

Installing

This package provides a set of Kentico-specific health checks that you can easily add to your ASP.NET Core project. Here's how you can do it:

1. First, make sure you have the necessary dependencies installed. You will need the Microsoft.Extensions.DependencyInjection package for the IServiceCollection interface.

2. Install this package via NuGet.

3. In your Startup.cs file (or wherever you configure your services), use the AddKenticoHealthChecks extension method on your IServiceCollection instance. Here's an example:

Add all Kentico Health Checks and Microsoft Health Checks

This method will add all the Kentico Health checks to your application.

public void ConfigureServices(IServiceCollection services)
{
    services.AddKenticoHealthChecks();
}

Add all Kentico Health Checks

This method will add all the Kentico Health checks to your application.

public void ConfigureServices(IServiceCollection services)
{
    services
    .AddHealthChecks()
    .AddKenticoHealthChecks();
}

Add specific Kentico Health Checks

This method will allow you the most flexibility to add only the health checks you want for your application.

public void ConfigureServices(IServiceCollection services)
{
    services.AddHealthChecks()
            .AddCheck<SiteConfigurationHealthCheck>("Site Configuration Health Check");
}

Middleware Registration

In your Startup.cs file (or wherever you configure your application), use the UseHealthChecks extension method on your IApplicationBuilder instance. This registers the health checks as middleware.Here's an example:

public void Configure(IApplicationBuilder app)
{    
    app.UseHealthChecks("/kentico-health");
}

Endpoint Registration

In your Startup.cs file (or wherever you configure your application), use the MapHealthChecks extension method on your IEndpointRouteBuilder instance. This registers the health checks as an endpoint. Here's an example:

app.UseEndpoints(endpoints =>
{
    endpoints.MapHealthChecks("/kentico-health");
}

Endpoint Registration with Custom Writer

In your Startup.cs file (or wherever you configure your application), use the MapHealthChecks extension method on your IEndpointRouteBuilder instance. This registers the health checks as an endpoint. This allows you to customize your HealthCheckOptions class, and specifiy a custom Response Writer.

Here's an example:

app.UseEndpoints(endpoints =>
{
    endpoints.MapHealthChecks("/kentico-health",
        new HealthCheckOptions()
        {
            AllowCachingResponses = true,
            ResponseWriter = HealthCheckResponseWriter.WriteResponse
        });
}

Health Checks

Application Initialized Health Check

The ApplicationInitializedHealthCheck class is an implementation of the IHealthCheck interface. It is used to perform a health check on the application initialization.

Azure Search Task Health Check

The AzureSearchTaskHealthCheck is a health check implementation that checks the Azure Search Task for any errors.

Email Health Check

The EmailHealthCheck class is an implementation of the IHealthCheck interface. It is used to perform a health check on the email service in the application.

EventLogHealthCheck

The EventLogHealthCheck class is an implementation of the IHealthCheck interface. It is used to perform a health check on the event log by investigating the last 100 event log entries for errors.

LocalSearchTaskHealthCheck

The LocalSearchTaskHealthCheck class is an implementation of the IHealthCheck interface. It is responsible for checking the health of local search tasks and determining if any errors are present. This health check is used to monitor the status of search tasks in the application.

SiteConfigurationHealthCheck

The SiteConfigurationHealthCheck class is an implementation of the IHealthCheck interface. It is responsible for checking the health of the site configuration in a CMS (Content Management System) application.

SitePresentationHealthCheck

The SitePresentationHealthCheck class is an implementation of the IHealthCheck interface. It is responsible for checking the health of the site presentation configuration in an ASP.NET Core application.

StagingTaskHealthCheck

The StagingTaskHealthCheck class is an implementation of the IHealthCheck interface. It is responsible for checking the health of staging tasks in a Kentico Xperience CMS application.

WebFarmHealthCheck

The WebFarmHealthCheck class is an implementation of the IHealthCheck interface provided by the Microsoft.Extensions.Diagnostics.HealthChecks namespace. It is used to perform health checks on the Kentico web farm servers.

WebFarmTaskHealthCheck

The WebFarmTaskHealthCheck class is an implementation of the IHealthCheck interface. It is responsible for checking the health of the web farm server tasks.
