AspNetCore.Diagnostics.HealthChecks | Enterprise HealthChecks for ASP.NET Core Diagnostics Package | Continuous Deployment library

I am trying to implement health checks in my blazor application. To do so, I have used the Microsoft.AspNetCore.Diagnostics.HealthChecks package among others. Below you can see sql and url health checks.

startup.cs

I'm trying to setup healthchecks for some required services to my dotnet core 3.1 API and I'm struggling on Amazon DynamoDB check.

We're using the Xabaril healthcheck packages and the DynamoDb one ask for a DynamoDBOptions that requires the AccessKey, SecretKey and RegionEndpoint.

I know the AWS SDK get this information from the environment Credentials profile configuration:

I am trying to implement a health check in one of my application which is .Netcore service by refering to Readme.md file.

Here is my code in startup.cs file

net core 5 application. I have added docker-file and running container which works fine. I have added health check into my application. In my application I have just added swagger and added sql health check. Below is my dockerfile

I'm evaluating the use of Microsoft Health Checks to improve routing of our internal load balancer. So far I'm very happy with the functionality provided by this feature and the community around it. However there's one thing I did not find yet and wanted to ask if it is possible out of the box:

The Health Checks seem to retrieve their own status as soon as they are requested. But because our service might have a hard time processing a lot of request in that given moment, the query to a thrid-party component like the SQL Server might take it's time to respond. Therefore, we would like to pre-evaluate that health check periodically (like every few seconds) and return that state when the health check api gets called.

The reason is, that we want our load balancer to get the health state as quickly as possible. Using pre-evaluated results seems to be good enough for our use case.

Now the question is: Is it possible to add a kind of "poll" or "auto-update" mechanism to the ASP.NET Core health checks? Or does this mean I have to implement my own health check returning values from a background service which pre-evaluates the results periodically?

Please note, I want to use pre-evaluated results on each request which is NOT HTTP Caching where the live result is cached for the next requests.

I've setup healthchecks for my app running in kubernetes. https://github.com/Xabaril/AspNetCore.Diagnostics.HealthChecks/blob/master/doc/k8s-ui-discovery.md

I see the healthchecks working under /healthui endpoint:

Kubernetes service yaml:

I have HealthCheckUI defined in my ConfigMaps yaml:

However I get an exception:

How does one setup HealthChecksUI in kubernetes?

I want to create HealthChecks portal via HealthChecksUI but with limited access with authorization.
Also I using Blazor to accomplish authorization dialog creation and receiving access token.

So I configuring HealthChecksUI:
