  • Cluster monitoring enables you to quickly view the health status of hosts and services.
  • Graphical metric monitoring and customization enable you to quickly obtain key information about the system.
  • Service property configurations can meet service performance requirements.
  • With cluster, service, and role instance functions, you can start or stop services and clusters in one click.
