Amazon Managed Service for Prometheus now provides Alert Manager & Ruler logs to help customers troubleshoot their alerting pipeline and configuration in Amazon CloudWatch Logs. Amazon Managed Service for Prometheus is a fully managed Prometheus-compatible monitoring service that makes it easy to monitor and alarm on operational metrics at scale. Prometheus is a popular Cloud Native Computing Foundation open source project for monitoring and alerting that is optimized for container environments. The Alert Manager allows customers to group, route, deduplicate, and silence alarms before routing them to end users via Amazon Simple Notification Service (Amazon SNS). The Ruler allows customers to define recording and alerting rules, which are queries that are evaluated at regular intervals. With Alert Manager and Ruler logs, customers can troubleshoot issues in their alerting pipelines including missing Amazon SNS topic permissions, misconfigured alert manager routes, and rules that fail to execute.
