In this release we are introducing support for agent-based monitoring with Prometheus (open-source systems monitoring and alerting system). Enable your cluster to use Prometheus exporters to collect metrics on your nodes and hosts. Avoid excessive SSH activity for monitoring and metrics collections and use SSH connectivity only for management operations.

You can use a set of new dashboards that uses Prometheus as the data source and gives access to its flexible query language and multi-dimensional data model with time series data identified by metric name and key/value pairs. In future releases, we will be adding more features such as allowing you to create and import your own dashboards.

We have also a new security feature to enable Audit Logging for MySQL based clusters. Enable policy-based monitoring and logging of connection and query activity executed on your MySQL servers.

Finally we have added support to easily scale out your cloud-deployed clusters by automating the cloud instance creation for the new DB node.
