As a MySQL database administrator, keeping a close eye on the performance of your MySQL server is crucial to ensure optimal database operations. PMM monitors the MySQL uptime: show global status like 'uptime'; Indicates the amount of time (seconds) the MySQL server has been running since the last restart.
