This alert monitors failures in exporting configuration history data from AWS Config to the designated S3 bucket. Export failures can result in incomplete records of resource configuration changes, affecting compliance auditing and troubleshooting efforts. The alert is triggered when an export job fails for more than one attempt within a monitoring period (e.g., 1 hour). Monitoring this metric helps ensure the integrity and availability of configuration history data for compliance reporting and operational insights. Customization Guidance: - Threshold: Adjust the threshold based on your tolerance for failed attempts before taking action (e.g., 1–3 failed attempts). - Monitoring Period: Set the monitoring period to align with the frequency of configuration export jobs (e.g., hourly or daily). - Notification Frequency: Configure notifications to provide timely updates on export failures without causing alert fatigue during transient issues. Action: If this alert is triggered, review the permissions and configuration of the S3 bucket to ensure AWS Config can write to it. Check for any service interruptions or connectivity issues and retry the export job.

This alert monitors insufficient permissions assigned to the AWS Config configuration recorder. Insufficient permissions can prevent AWS Config from recording resource configurations, leading to gaps in compliance monitoring and auditing. The alert is triggered when the configuration recorder lacks the required permissions to record resource configurations for more than 10 minutes. Monitoring this metric helps ensure that AWS Config has the necessary permissions to track and record resource changes continuously, supporting compliance and operational audits. Customization Guidance: - Threshold: Set the threshold based on the acceptable duration for insufficient permissions in your environment (e.g., 5–10 minutes). - Monitoring Period: Adjust the monitoring period to match the criticality of compliance tracking in your system. - Notification Frequency: Configure notifications to provide immediate alerts for prompt resolution while avoiding excessive alerts during transient issues. Action: If this alert is triggered, review and update the IAM role associated with the configuration recorder to ensure it has the required permissions for all target resources. Test the configuration recorder to confirm functionality after updates.

This alert monitors the drop in the number of configuration items recorded by AWS Config. A decrease in recorded items may indicate issues with resource monitoring, which can lead to gaps in compliance checks and auditing. The alert is triggered when the number of configuration items recorded drops below a specified threshold (e.g., less than 10 items in an hour). Monitoring this metric helps ensure that AWS Config is functioning correctly, providing continuous tracking of resource changes to maintain compliance and security. Customization Guidance: - Threshold: Adjust the threshold based on your typical resource changes and expected recording rates. - Monitoring Period: Set the monitoring period to reflect your environment's activity patterns, such as high or low resource update periods. - Notification Frequency: Configure notification frequency to ensure timely response without causing alert fatigue. Action: If this alert is triggered, consider investigating potential issues with AWS Config service permissions, connectivity to AWS Config, or anomalies in resource activity. Validate the configuration recorder and delivery channel setup.
