監(jiān)測Elasticache的Failover event
Cluster Status是通過describe-cache-clusters獲取的渠旁，而describe-cache-clusters目前能顯示的狀態(tài)只有“available , creating , deleted , deleting , incompatible-network , modifying , rebooting cluster nodes , restore-failed , or snapshotting” 不會顯示類似 recovering或者 unavailable這樣的狀態(tài)巴粪，通過控制面板的Cluster Status是無法檢測Failover這種行為的轧粟。
利用describe-event來看才是最準確的：
describe-events
[--source-identifier ]
[--source-type ]
[--start-time ]
[--end-time ]
[--duration ]
[--cli-input-json ]
[--starting-token ]
[--page-size ]
[--max-items ]
[--generate-cli-skeleton ]
