This topic describes how to set the monitoring frequency of an ApsaraDB RDS for MySQL instance.

Background information

ApsaraDB RDS for MySQL provides the following three monitoring frequencies:

  • Every 5 Seconds
  • Every 60 Seconds
  • Every 300 Seconds
Note ApsaraDB RDS allows you to query the monitoring data from the last 30 days or less. You may not be able to query the monitoring data over a time range of more than 30 days.

The following table describes the supported monitoring frequencies.

Instance configuration Every 5 Seconds Every 60 Seconds Every 300 Seconds
High-availability or Enterprise Edition with a memory capacity less than 8 GB Not supported Supported free of charge Supported free of charge (This is the default monitoring frequency.)
High-availability or Enterprise Edition with a memory capacity greater than or equal to 8 GB Supported with fees required Supported free of charge (This is the default monitoring frequency.) Supported free of charge
Basic Edition Not supported Not supported Supported free of charge (This is the default monitoring frequency.)
Note If your RDS instance uses standard or enhanced SSDs, the monitoring frequency is fixed to once every 60 seconds. In this case, all changes to the monitoring frequency do not take effect.

Billing

The monitoring frequencies that are supported with fees required are charged at an hourly rate based on the pay-as-you-go billing method. For example, if your RDS instance uses the Every 5 Seconds monitoring frequency, you are charged an hourly rate of USD 0.012.
