> Currently, the health check library [ignores *all* failures|https://github.com/apache/mesos/blob/b053572bc424478cafcd60d1bce078f5132c4590/src/health-check/health_checker.cpp#L192-L197] from the task’s start (technically from the health check library initialization) [until after the grace period ends|https://github.com/apache/mesos/blob/b053572bc424478cafcd60d1bce078f5132c4590/include/mesos/v1/mesos.proto#L403].
> This behaviour is misleading. Once the health check succeeds for the first time, grace period rule for failures should not be applied any more.
> For example, if the grace period is set to 10 minutes, the task becomes healthy after 1 minute and fails after 2 minutes, the failure should be treated as a normal failure with all the consequences.
