The correct answer is D. Installing the StackDriver Agent and configuring the MySQL plugin is the most straightforward and least development-intensive approach to achieve the monitoring and alerting requirements for MariaDB on GCE VM Instances using StackDriver. The StackDriver Agent is designed to collect system and application metrics from virtual machine instances and send them to StackDriver Monitoring. The MySQL plugin allows the collection of MySQL-specific metrics, which include network connections, disk IO, and replication status, making it suitable for monitoring MariaDB as well.
