根据官方文档，逐步搭建数据守护，在启动Monitor的时候报错，如下：
dmdba@dm3 bin]$ ./dmmonitor /opt/dmdbms/data/dmmonitor.ini

因为报错是oguid不一致，所以检查主备库的oguid，但是是一样的
网上查询相关案例，说是因为dmmonitor.ini的组名和dmwatcher.ini的组名不一致导致，但是检查发现还是一样的
最后检查dmmonitor.ini配置文件发现，是oguid的那一行手误注释掉了，导致整个问题，去掉注释后重启监视器成功
[root@dm3 data]# cat dmmonitor.ini
MON_DW_CONFIRM = 1 #确认监视器模式
MON_LOG_PATH = /opt/dmdbms/data/log #监视器日志文件存放路径
MON_LOG_INTERVAL = 60 #每隔 60s 定时记录系统信息到日志文件
MON_LOG_FILE_SIZE = 32 #每个日志文件最大 32M
MON_LOG_SPACE_LIMIT = 0 #不限定日志文件总占用空间
[GRP1]
#MON_INST_OGUID = 453331 #组 GRP1 的唯一 OGUID 值 #以下配置为监视器到组 GRP1 的守护进程的连接信息，以―IP:PORT‖的形式配置
#IP 对应 dmmal.ini 中的 MAL_HOST，PORT 对应 dmmal.ini 中的 MAL_DW_PORT
MON_DW_IP = 192.168.48.133:65101
MON_DW_IP = 192.168.48.134:65121
