   ### Question
   - What do you want to know?
   I'd like to monitor my Liferay Portal CE 7.2 GA1 instance with Apache SkyWalking 6.5.0. Liferay is a Java CMS. On that DEV environment following software is installed: Ubuntu 18.04.3 LTS, OpenJDK 11.0.4, Apache Tomcat 9.0.17 and MariaDB 10.1.41 as Liferay storage.
   
   In than configuration the MariaDB database is not recognized by SkyWalking completely.
   
   On a different VM with Ubuntu 19.10, Azul Zulu JDK 11.0.5 and MySQL 5.7.28 Skywalking recognizes the DB just fine. On that environment the DB is a different server, on the first one everything is on one machine.
   
   Is that a bug or SkyWalking just doesn't work with MariaDB and it's a missing Feature? Or coud it be a configuration issue? (Config is on both environments is similar).
   
   Thank you.

   ### Bug
   - Which version of SkyWalking, OS and JRE?
   SkyWalking 6.5.0, Ubuntu 18.04.3 LTS, OpenJDK 11.0.4, Apache Tomcat 9.0.17 and MariaDB 10.1.41
   - Which company or project?
   
   - What happen?
   If possible, provide a way for reproducing the error. e.g. demo application, component version.
   SkyWalking doesn't "see" the MariaDB database of the monitored application.
