In Preview3 IHealthCheck doesn't seem to be able to return granular HealthStatus about diagnostics

Thanks for contacting us, @alecor191.
@rynowak, can you please handle this? Thanks!

Hi @alecor191 - this is an intentional change - we want the application developer to be able to configure the status reported by a health check. This is essential if the health check is supplied by a library that you didn't write.

For your use case, I a few options:

You can include these details in the data returns by your health check https://github.com/aspnet/Diagnostics/blob/release/2.2/samples/HealthChecksSample/GCInfoHealthCheck.cs#L60 and then configure a custom writer to include information in the response https://github.com/aspnet/Diagnostics/blob/release/2.2/samples/HealthChecksSample/CustomWriterStartup.cs

Or you could just register two health checks. Write a check that accepts 'days remaining' as a parameter, and register the same code twice, once with 30 days remaining and once with 0 days. Then, configure one of them to report degraded when it fails.

I hope this helps.

Thanks @rynowak!

Those two approaches should work fine for me. I just found the previous approach a bit more convenient/simple in my setup. However, I understand that there are other scenarios where a more generic approach is required.
