SHOW instance_name LOG FILES
The command lists all log files used by the instance. The result set contains the path to the log file
and the log file size. If no log file path is specified in the instance section of the configuration file (for
example, log=/var/mysql.log), the Instance Manager tries to guess its placement. If Instance
Manager is unable to guess the log file placement you should specify the log file location explicitly by
using a log option in the appropriate instance section of the configuration file.
mysql> SHOW mysqld LOG FILES;
+-------------+------------------------------------+----------+
| Logfile | Path

| ERROR LOG | /home/cps/var/mysql/owlet.err
| GENERAL LOG | /home/cps/var/mysql/owlet.log
