text: Check the MariaDB log files
  NOTE: We are in the process of modifying the configuration for many Bitnami stacks. On account of these changes, the file paths and commands stated in this guide may change depending on whether your Bitnami stack uses MySQL or MariaDB. To identify which database server is used in your stack, run the command below:
  $ test -d /opt/bitnami/mariadb && echo "MariaDB" || echo "MySQL"
  The output of the command indicates which database server (MySQL or MariaDB) is used by the installation, and will allow you to identify which guides to follow in our documentation for common database-related operations.
  The main MariaDB log file is located at /opt/bitnami/mariadb/logs/mysqld.log, on the MariaDB database server host:
  MariaDB database performance and connectivity can be affected by low disk space and/or low available memory. These resources can be checked using the df and free commands, as described in the server performance troubleshooting guide.
