You can configure thresholds in your AWS CloudWatch monitor to define when it enters Critical or Warning state.
In the monitor settings go to the Thresholds tab and click Add Threshold.
Choose the CloudWatch metric to define the condition.
- Currently, only one AWS CloudWatch metric can be used in the threshold. Possibility to use more than one metric in the threshold will be added in the upcoming releases.
- If no data is received for a CloudWatch metric used in the threshold, the threshold will not be violated unless you have used the “Not equal” operator in the metric condition, in which case the threshold will be violated.
See Thresholds for more info.
