安裝head
head插件可以用來快速查看elasticsearch中的數據概況以及非全量的數據，也支持控件化查詢和rest請求，但是體驗都不是很好。
一般就用它來看各個索引的數據量以及分片的狀態。
[root@localnode1 bin]# ./plugin install mobz/elasticsearch-head

安裝sense
sense插件可以方便的執行rest請求，但是中文輸入的體驗不是很好。
安裝sense只需要在Kibana端安裝插件即可，插件會自動安裝到kibana的應用菜單中。
[hdfs@localnode1 bin]$ kibana plugin -install elastic/sense
-bash: kibana: command not found
[hdfs@localnode1 bin]$ ./kibana plugin -install elastic/sense
Please specify either --install, --remove, or --list.
[hdfs@localnode1 bin]$ ./kibana plugin --install elastic/sense

安裝完成后，可以通過導航面板進入，也可以直接訪問http://localhost:5601/app/sense
安裝marvel
marvel工具可以幫助使用者監控elasticsearch的運行狀態，不過這個插件需要license。安裝完license后可以安裝marvel的agent，agent會收集elasticsearch的運行狀態。
然后在Kibana段安裝marvel插件，這個插件與sense類似，都集成在kibana的導航列表面。
