> Triggers determine whether to generate events by measuring if the time since the last event is greater than {{waitFor}} or not. That is not the intended purpose of {{waitFor}}. They should actually keep checking whether the violation remains for the duration of the {{waitFor}} time, and only then generate events.
> This is further complicated by the fact that all triggers are paused whenever an event is being processed (SOLR-11747). It seems that instead they should not be paused but continue running to properly track the cluster state - they just should not generate any events, or their events should be IGNORED.
