O&M architecture

The O&M architecture provides visualized, standard, and granular system operations management to

help the system administrators operate and maintain the system with ease for higher efficiency. As shown in Figure-1, the O&M architecture provides basic, advanced, scenario-based, and custom O&M capabilities. Figure-1 O&M architecture

• Basic O&M capabilities—Help you gain a holistic view of the NSphere platform in tables and graphs. Available information includes resource usage statistics and distribution, network topology of hosts, VMs, and resources, task progresses, and log.

• Advanced O&M capabilities—Provide actionable statistics and insights.

General O&M recommendations

• Review the health state and resource usage of the system daily.

• Subscribe to system alarm notifications. After receiving an alarm, take action as recommended to clear the alarm. On the management platform, you can maintain a list of maintenance records for each alarm.
