To continuously enhance the functional completeness and data accuracy of CloudMonitor, we will perform an upgrade on certain CloudMonitor metrics for ApsaraDB for SelectDB, ApsaraDB for OceanBase, and ApsaraDB for ClickHouse starting from 13:00:00 to 20:00:00 (UTC+8) on June 24, 2026.

• Upgrade Content: Upgrade of the underlying CloudMonitor computing functions.
• Upgrade Impact: During the upgrade process, there may be significant data fluctuations, and alert notifications may be triggered. Data will return to normal once the upgrade is complete.

This optimization does not involve any billing changes, nor does it affect the use of other features.
