Set monitoring frequency

Background information

The RDS console provides abundant performance metrics for users to conveniently view and know the running status of the instances. You can use the RDS console to set the monitoring frequency, view monitoring data of a specific instance, create monitoring views, and compare instances of the same type under the same account.

Before May 15, 2018, two monitoring frequencies were available:

• once per 60 seconds (monitoring period: 30 days)

• once per 300 seconds (monitoring period: 30 days)

However, the minute-level monitoring frequencies were not enough for certain users and maintenancen personnel. Therefore, since May 15, 2018, RDS has introduced the second-level monitoring frequency. This faciliates problem locating and improves customer satisfaction.

• once per 5 seconds (monitoring period: 7 days) The monitoring frequency beyond 7 days is once per minute.

• The detailed monitoring policies are described in the following table.

  Instance type	once per 5 seconds	once per minute (60 seconds)	once per 5 minutes (300 seconds)
  Basic Edition	Not supported	Supported for free	Default configuration
  High Availability or Finance Edition: Memory < 8 GB	Not supported	Supported for free	Default configuration
  High Availability or Finance Edition: Memory >= 8 GB	Supported (Not free)	Default configuration	Supported for free

Restrictions

• You can configure second-level monitoring for instances that meet the following conditions:

  • The instance is located in these regions: China (Hangzhou), China (Shanghai), China (Qingdao), China (Beijing), China (Shenzhen)
  • The instance is an RDS for MySQL instance.
  • The instance storage type is local SSDs.
  • The instance memory is 8 GB or more.

• All engines (MySQL, SQL Server, PG, PPAS) and database versions support these monitoring frequencies: once per 60 seconds; once per 300 seconds.
