This topic describes how to set the monitoring frequency for an RDS instance. ApsaraDB for RDS provides more than one monitoring frequency for you to select.
Two monitoring frequencies provided before May 15, 2018
- Once per 60 seconds (monitoring period: 30 days)
- Once per 300 seconds (monitoring period: 30 days)
Second-level monitoring frequency introduced since May 15, 2018
Minute-level monitoring frequencies cannot meet monitoring requirements of some users and maintenance personnel. Therefore, since May 15, 2018, RDS has introduced second-level monitoring frequencies. This facilitates problem locating and improves customer satisfaction.
Once per 5 seconds (monitoring period: 7 days), turning to once per minute since the eighth day
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)|

|High-availability or Enterprise Edition: Memory < 8 GB||Not supported||Supported for free||Default configuration|
