Using grafana to display info from the MYSQL master
Hello all, I feel this is really obvious task but I just cant sort it out.
We have many Percona master/slave pairs which are monitored using prometheus-mysqld-exporter. I need to display the cpu load factor and other items for the master server within grafana. Has anybody got a grafana expression to isolate the master_hosts. It is easy to get any stat for the slave. But how do I get info for the master?
