Hi @lirulei and thanks for this first contribution.

A preview alert was added for tracking the connection count. Can you explain why you choose

sum by(instance) (mysql_info_schema_processes_by_host) / sum by(instance) (mysql_global_variables_max_connections) * 100 > 80

vs

max_over_time(mysql_global_status_threads_connected[1m]) / mysql_global_variables_max_connections * 100 > 80

?

Also, I moved your work into _data/rules.yml.
