使用gha_ctl monitor 命令，对数据库集群状态进行监控。
语法格式
gha_ctl monitor all/server/gtm/coordinator/datanode/dcs
<-c cluster> <-H> -l
dcslist
其中参数说明：
-c 参数：表示数据库名称，为可选字段。缺省默认值gbase。
dcslist 为DCS 地址，一般情况下可以只列出一个节点地址，其他节点会自动同步消息。
为了保证高可用，也可以列出所有节点地址。
-H 参数：如指定该参数，则集群状态结果以表格形式展示。
状态
running：节点处于正常运行状态

stopped：节点处于正常停止状态
unstable：节点处于不稳定的中间状态。检查故障处理。
示例
具体操作命令如下：
[gbase@gbase8c ~]$ gha_ctl monitor all -l http://10.0.7.16:2379 -H
若返回运行中，则表示集群节点处于运行状态：
