Currently the ceilometer-expirer doesn't delete expired AlarmChanges. Remained AlarmChanges would be cause of wasted disk-space and slow response. This patch aims to delete AlarmChanges. This patch adds a new config option: [database] alarm_history_time_to_live = -1 Implements: blueprint delete-alarmhistory DocImpact Change-Id: Ib6bda6df720cf8514b621bfe13dd3acba941949f
