Amazon RDS metrics and alerts

This documentation contains a list of metrics and alerts that are available when monitoring Amazon RDS SQL Server instances and the requirements for collecting them. If you can't find a specific metric or alert you would like to use when monitoring your RDS instances, send us feedback.

Metrics

Machine metrics

To get access to machine metrics in Amazon RDS you need to provide SQL Monitor with your AWS API credentials. To learn how to do that, please see Add Amazon RDS SQL Server.
The following table summarizes the machine metrics that SQL Monitor can  collect, for Amazon RDS servers, and which of those are collected only if Amazon RDS Enhanced Monitoring is enabled for your Amazon RDS instances:

Metric nameAmazon RDS Enhanced Monitoring required?
Machine: Processor time-
Machine: Memory usedYes
Network utilization-
Disk usedYes
Disk capacity Yes
Disk read and write bytes/secYes
Disk transfers/sec-

Alerts

Alerts are based on metrics, so if the metric, or metrics, used by an alert require AWS API credentials or RDS Enhanced Monitoring to be collected, the alert will consequently have the same requirements.
The following table describes the requirements for the supported alerts:
