　　 Linux中的命令NetCat有「瑞士軍刀」的美譽。咱們能夠經過nc命令查看Zookeeper的一行屬性數據。在Zookeeper中有不少四字命令，彙總以下：java

序號	使用命令	輸出說明
1	echo conf \| nc 10.9.3.253 2181	輸出Zookeeper相關服務的詳細配置信息，如客戶端端口，數據存儲路徑、最大鏈接數、日誌路徑、數據同步端口、主節點推舉端口、session超時時間等等
2	echo cons \| nc 10.9.3.253 2181	輸出鏈接到Zookeeper的服務器信息，包括隊列、數據接收量、數據發送量、sessionID、操做延時、最後的操做信息等等
3	echo crst \| nc 10.9.3.253 2181	重置當前的全部鏈接、會話等等
4	echo dump \| nc 10.9.3.253 2181	列出未經處理的會話和鏈接信息
5	echo envi \| nc 10.9.3.253 2181	列出zookeeper的版本信息、主機名稱、Java版本、java_home、class_path、服務器名稱、當前登錄用戶名、目錄等等；
6	echo ruok \| nc 10.9.3.253 2181	Are You Ok的縮寫，測試服務器是否正在運行，若是在運行返回imok，不然返回空
7	echo srst \| nc 10.9.3.253 2181	重置Zookeeper的全部統計信息
8	echo srvr \| nc 10.9.3.253 2181	列出zookeeper的版本信息、數據接收/發送量、鏈接數、節點模式、Node數、最大/平均/最小延遲數
9	echo stat \| nc 10.9.3.253 2181	列出鏈接客戶端列表、最大/平均/最小延遲數、數據接收/發送量、鏈接數、節點總數、模式
10	echo wchs \| nc 10.9.3.253 2181	列出watch的總數，鏈接數
11	echo wchp \| nc 10.9.3.253 2181	列出全部watch的路徑及sessionID
12	echo mntr \| nc 10.9.3.253 2181	列出集羣的關鍵性能數據，包括zk的版本、最大/平均/最小延遲數、數據包接收/發送量、鏈接數、zk角色（Leader/Follower）、node數量、watch數量、臨時節點數
