Instance Method Details

#handle_failure!(options) ⇒ Object

this handles issues where instance cannot be restarted due to normal reboot. since hard stopping takes longer, we don’t want to do it unless necessary. the reset failure count is semi wonky because it will reset even if success hasnt yet been reached, however it is much less complicated than trying to query state of multiple instances. basically if threshold is reached, hard stop the instances, then on next pass since we reset the failure count, it should attempt normal reboot, which will cause the instances to start
