Amazon CloudWatch Application Signals adds new SLO capabilities

Amazon CloudWatch Application Signals now offers three new console based capabilities for Service Level Objectives (SLOs): SLO Recommendations, Service-Level SLOs, and SLO Performance Report. CloudWatch Application Signals helps customers monitor and improve application performance on AWS. It automatically collects data from applications running on services like Amazon EC2, Amazon ECS, and Lambda. Previously, customers had to manually set SLO thresholds without data-driven guidance, often leading to misconfigured targets and alert fatigue. They also lacked visibility into overall service health across operations and had no way to track reliability trends over time or generate calendar periods performance reports. These new capabilities address each of those gaps, making it easier to set data-driven reliability targets, monitor overall service health, and identify reliability trends before they become incidents.

SLO Recommendations analyzes 30 days of service metrics (P99 latency and error rates) to suggest appropriate reliability targets. Customers can validate proposed targets before implementation to help reduce the cognitive and operational effort needed for new SLO deployments. Service-Level SLOs provide a holistic view of service reliability across all operations, simplifying alignment between technical monitoring and business objectives. SLO Performance Report provides historical analysis aligned with calendar periods, supporting daily, weekly, and monthly intervals. These capabilities support key use cases including proactive reliability management, SLO threshold optimization, and business reporting aligned with calendar periods.

These features are available in all AWS Regions where Amazon CloudWatch Application Signals is available. Pricing is based on the number of inbound and outbound requests to and from applications, plus Service Level Objectives charges, with each SLO generating 2 application signals per service level indicator metric period.
