healthEventsConfig
Defines the threshold percentages and other configuration information for when Amazon CloudWatch Internet Monitor creates a health event. Internet Monitor creates a health event when an internet issue that affects your application end users has a health score percentage that is at or below a specific threshold, and, sometimes, when other criteria are met.
If you don't set a health event threshold, the default value is 95%.
For more information, see Change health event thresholds in the Internet Monitor section of the CloudWatch User Guide.
