Not specific to mariadb (similar things happen with the standalone mytop)
but noticed this while testing:
$ mytop
Cannot connect to MySQL server. Please check the:
* database you specified "test" (default is "test")
* username you specified "root" (default is "root")
* password you specified "" (default is "")
* hostname you specified "localhost" (default is "localhost")
* port you specified "3306" (default is 3306)
* socket you specified "/var/run/mysql/mysql.sock" (default is "")
The options my be specified on the command-line or in a ~/.mytop
config file. See the manual (perldoc mytop) for details.
Here's the exact error from DBI. It might help you debug:
