AWS AmazonCloudWatch documentation change
Summary
Clarified Network Health Indicator (NHI) metric scope to focus on AWS network paths
Security assessment
Improves accuracy of network monitoring documentation but does not relate to security vulnerabilities or introduce security features.

NHI can be one of two values: 1 or 0. A value of 1 indicates that Network Synthetic Monitor observed a network degradation within the AWS controlled network path. A value of 0 indicates that Network Synthetic Monitor did not observe any network degradation along the path. Observing the NHI value enables you to more quickly gain awareness of the cause of network issues.

NHI can be one of two values: 1 or 0. A value of 1 indicates that Network Synthetic Monitor observed a network degradation within the AWS controlled network path. A value of 0 indicates that Network Synthetic Monitor did not observe any network degradation for the AWS network along the path. Using the NHI value enables you to more quickly gain awareness of the cause of network issues. For example, you can set alerts on the NHI metric so you're notified about ongoing issues with the AWS network along your network paths.
