Hello, sorry for my English, there is such a problem, I configured Percona XtraDB Cluster on 3 servers, everything is working fine now, but how do I look at the time delay of the slave from the master? If I’m watching now
mysql -e "show slave status\G"
then I get nothing from this documentation https://www.percona.com/blog/2014/05/02/how-to-identify-and-cure-mysql-replication-slave-lag/ swears at
Detected value is empty; something failed? Trigger exit status: 0
Seconds_Behind_Master parameter is not defined.
How can I see the delay?
