Georg Henzler commented on SLING-6855:
--------------------------------------

[~bdelacretaz] Thanks for fixing this - I light-heartedly only tested with 
synchronous tests. I think the fix is good (except that I maybe would use 
{{@Reference  HealthCheckResultCache cache}} in {{AsyncHealthCheckExecutor}} 
instead of passing it in as parameter)

> The cache keeps one result of each type, by design
Yes this is intended - if someone wants to keep the full history this is better 
to be done in a monitoring tool that can store the historic results. Here it is 
"only" about  changing the result status if something went wrong in the past, 
then one per type is sufficient.

> If we agree on how this feature works we should document it
I agree, will do so on Monday! (I will also look into how to create a release, 
have not done that yet). 

> Sticky Results Support

>            Assignee: Georg Henzler
>             Fix For: Health Check Annotations 1.0.6, Health Check Core

> Introduce HC service property {{hc.warningsStickForMinutes}} to allow old 
> WARN/CRITICAL/HEALTH_CHECK_ERROR results to be sticky (see also 
> http://sling.markmail.org/thread/tawikgt7bqxvnlj5#query:+page:1+mid:57hhg55hekr7ib33+state:results)
> --- Original Request ----
> *Create ResultRegistry to provide health check behavior for executing code 
> that does not want a HealthCheck* 
> I want to provide a Registry service that can be leveraged to provide health 
> check results.
> These results can be for a period of time through an expiration, until the 
> JVM is restarted, or added and later removed.
> This can be useful when code observes a specific (possibly bad) state, and 
> wants to alert through the health check API that this state has taken place.
>  Some examples: 
>  An event pool has filled, and some events will be thrown away.
>   This is a failure case that requires a restart of the instance.
>   It would be appropriate to trigger a permanent failure.
>    
>  A quota has been tripped. This quota may immediately recover, but it is 
> sensible to alert for 30 minutes that the quota has been tripped.
>  If you expect the failure will clear itself within a certain window, setting 
> the expiration to that window can be ideal.
> GHPR to follow
