Reviewing runtime coverage statistics and troubleshooting issues
After you enable Runtime Monitoring and the GuardDuty security agent gets deployed to your resource, GuardDuty provides coverage statistics for the corresponding resource type and individual coverage status for the resources that belong to your account. Coverage status is determined by making sure that you have enabled Runtime Monitoring, your Amazon VPC endpoint has been created, and the GuardDuty security agent for the corresponding resource has been deployed. A Healthy coverage status indicates that when there is a runtime event related to your resource, GuardDuty is able to receive the said runtime event through the Amazon VPC endpoint, and monitor the behavior. If there was an issue at the time of configuring Runtime Monitoring, creating an Amazon VPC endpoint, or deploying the GuardDuty security agent, the coverage status appears as Unhealthy. When the coverage status is unhealthy, GuardDuty will not be able to receive or monitor the runtime behavior of the corresponding resource, or generate any Runtime Monitoring findings.
The following topics will help you review coverage statistics, configure EventBridge notifications, and troubleshoot the coverage issues for a specific resource type.
