Teams working with distributed applications accumulate logs across multiple log groups, including application logs, access logs, and audit trails. When something needs investigating, an engineer opens the console and starts writing queries from scratch. The same query gets written differently by different people. The results lack context because the log event does not contain who […]

Editor’s note (July 2026): This post has been updated to reflect the launch of Amazon CloudWatch Coding Agent Insights, a purpose-built experience for monitoring AI coding agent usage. The dashboard deployment section now references Coding Agent Insights for CloudWatch users, with the custom PromQL dashboard retained for Amazon Managed Grafana. If your engineering organization uses […]

If you run Kubernetes or microservices workloads on AWS, you probably track latency, request durations, and other value distributions with Prometheus histograms. To do that with classic histograms, you predefine a set of bucket boundaries, and Prometheus emits one time series per boundary plus a sum and a count. A single latency histogram with 20 […]

Welcome to the first edition of the AWS Observability ICYMI (In Case You Missed It) recap! The first five months of 2026 has been transformational for AWS observability with over 40 launches across Amazon CloudWatch, AWS X-Ray, Amazon Managed Grafana, and Amazon Managed Service for Prometheus. Two major themes defined this period: OpenTelemetry as the […]

Organizations managing workloads on AWS rely on AWS CloudTrail to answer the fundamental questions: Who did what, where, and when? Since January 2022, customers have stored their CloudTrail activity logs in CloudTrail Lake, a managed data lake purpose-built for capturing, storing, querying user and API activity across their AWS environment.  As organizations scale across multiple […]

Editor’s note (July 2026): This post has been updated to reflect the general availability of Amazon CloudWatch native OpenTelemetry metrics ingestion and PromQL support, including new capabilities and revised pricing. If you run Kubernetes or microservices workloads on AWS, your metrics likely carry dozens of labels: namespace, pod, container, node, deployment, replica set, and custom […]

Introduction Enterprise applications using AWS X-Ray generate large volumes of distributed tracing data across multiple services. Static sampling strategies keep costs down by capturing a fixed percentage of traffic. However, they frequently miss critical data during intermittent failures or sudden latency spikes. Tracing every request for maximum visibility at scale may increase sampling costs for […]

When a critical service fails, you need to know how much revenue you’re losing, not just that latency has increased. This post shows you how to integrate business metrics with CloudWatch Application Signals to see both technical performance and business impact in one unified view. With CloudWatch Application Signals, you can view metrics, traces, and […]

Introduction Global, distributed AWS architectures are the backbone for customers seeking high availability, resilience, and regulatory compliance. Workloads are commonly deployed across multiple AWS Regions and Availability Zones (AZs), often using AWS PrivateLink to connect services securely and privately across Amazon Virtual Private Cloud (Amazon VPC) networks. This approach enhances security and separation while requiring […]

Amazon CloudWatch RUM now supports iOS and Android applications, expanding real user monitoring beyond web applications. Developers and SREs can now quickly isolate mobile application issues and improve end-user experience, with visibility into performance metrics such as screen load times, crash rates, and API latencies.
