This topic describes how to set the monitoring frequency of an ApsaraDB RDS for MySQL instance.
Background information
ApsaraDB RDS supports the following monitoring frequencies:
- Every 5 seconds (paid feature)
- Every 60 seconds
- Every 300 seconds
Note ApsaraDB RDS allows you to query the monitoring data from the most recent 30 days. 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 type | Every 5 seconds | Every 60 seconds | Every 300 seconds |
|---|---|---|---|
| RDS High-availability Edition or RDS 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.) |
| RDS High-availability Edition or RDS 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 |
| RDS Basic Edition | Not supported | Not supported | Supported free of charge (This is the default monitoring frequency.) |
| RDS Cluster Edition | Not supported | Supported free of charge | Supported free of charge |
Note If your RDS instance uses standard SSDs or enhanced SSDs (ESSDs), the monitoring frequency is fixed as every 60 seconds. Changes of the monitoring frequency do not take effect.
