主从服务器延迟检测， 从服务器mk-heartbeat命令显示信息如何解读问题请教

yepkeepmoving

公司数据库偶尔出现订单主从服务器延迟现象，而当时通过show slave status \G查看时，看到Seconds_Behind_Master: 0
但确实是主从查询不一致，于是想进一步查看主从延迟情况，采用了mk-heartbeat工具
但具体显示的信息不是很明白，还请知道的给予解释下，多谢各位
问题：从服务器输入检测命令后显示的信息具体含义是什么
开始没有数据传输，延迟为0，每列和每行数据代表什么意思呢？
具体检测命令如下：
主服务器： mk-heartbeat -D mm  --update -h10.72.16.85 -uroot -padmin   --daemonize
从服务器： mk-heartbeat -D mm --monitor -h10.72.16.86 -uroot -padmin123
从服务器显示信息如下：
