Upgrade of Metrics for ApsaraDB RDS for PostgreSQL and ApsaraDB RDS for SQL Server on August 31, 2022

[Alibaba Cloud][CloudMonitor][Announcement of Upgrade of Metrics]
Time window: 10:00 (UTC+8) to 22:00 (UTC+8) on August 31, 2022
Adjustment: From 10:00 (UTC+8) to 22:00 (UTC+8) on August 31, 2022, CloudMonitor will upgrade and adjust the metrics for ApsaraDB RDS for PostgreSQL and ApsaraDB RDS for SQL Server. Description:
1. The latency of minute-timing metrics is reduced.
2. High-precision metrics that are accurate to seconds are provided. You can view or obtain relevant metric data by activating Hybrid Cloud Monitoring.
3. The calculation issues related to the read-only synchronization latency (PG_RO_ReadLag) and read-only stream replication status (PG_RO_StreamingStatus) metrics in ApsaraDB RDS for PostgreSQL are fixed.
Impact: For instances other than read-only ApsaraDB RDS for PostgreSQL instances, the PG_RO_ReadLag and PG_RO_StreamingStatus metrics are no longer displayed in the CloudMonitor console.
We apologize for any inconvenience that may arise because of the upgrade. If you have any questions, you can submit a ticket or contact the service hotline at any time.
