I am using the health check for .Net core api and I am using latest health check package.
I am facing issue with HealthCheckExecutionHistory history.
If i use the as per the sample

 .AddCheck(name: "random", () =>
                {
                    return DateTime.UtcNow.Second % 2 == 0 ? HealthCheckResult.Healthy() : HealthCheckResult.Unhealthy();
                })

This service returns both Healthy and unhealthy status. and i can see the entry in exection histry and sma eon the UI.

But in My services I am using

.AddCheck(name: "random", () =>
                {
                    return HealthCheckResult.Healthy() ;
                })

which will return healthy if my service is up and running.
and in case of service failure UI client will get request failure instead of unhealthy json response.
in this case UI client will not add history entry and only show Unhealthy status.
I want history to be maintained in case of whole service service.
Is there any thing I am missing?
