> Just checking for service checks that were run within the last hour does not 
> seem to be a warranty of anything. For example, user could install cluster, 
> run service checks once, and then enable security/LDAP/change configuration 
> as required by some pre-upgrade check/whatever, and still have Health Check 
> passing.
> So the current idea is to check configuration change history and compare 
> config change timestamps with last time the service check for related service 
> was run.
> Also log to Ambari log timestamps of latest service checks for services, and 
> timestamps of latest service config changes (INFO level)
