Purpose: This alert will tell us that replication is not running on a replica DB

Scenario: MySQL Slave SQL thread has not been running on <server> for 5m .

Resolution: Check the replica for errors with a query.

Manual Action Steps:

1. Log into the replica
2. SHOW SLAVE STATUS;
3. check the mysql error and fix it if possible
4. STOP SLAVE;
5. SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1; This skips the problem query
6. START SLAVE
