Switching a Monitor

Constraints

• This function is not applicable to API monitors.
• When the service database is abnormal, the automatic switchover will be triggered and take 10 seconds to complete. During this period, services may be interrupted.
• After data center 1 recovers, click Switch Back in the row that contains the target monitor.
• If DC 1 (active) is abnormal, MAS automatically sets DC 2 to active. However, MAS will not perform automatic switchover if DC 2 is active and becomes abnormal.

Switching a Monitor

1. Log in to the MAS console. On the Multi-Active Instances page, click an instance whose namespace type is Intra-city multi-active.
2. Go to the Applications tab page, click Switch Over Monitor, and click Switch Over on the Monitoring Status page.
3. Click OK.

   If the target data center is abnormal but you have to switch over the monitor, select the checkbox to confirm the switchover, and click OK.

   This may cause data loss.
