Amazon CloudWatch is a managed monitoring and observability service from Amazon Web Services. It collects metrics, logs and traces from AWS resources and, through an OpenTelemetry-compatible agent, from workloads running outside AWS. Users can set alarms and anomaly detection, build dashboards, query telemetry with PromQL or SQL, and use AI-assisted investigation features. It is delivered as a cloud service and managed through the AWS console, APIs and command-line tools.
Amazon.com, Inc. is headquartered in Seattle, so the provider is subject to US jurisdiction, including the CLOUD Act. CloudWatch has endpoints in several European AWS regions, among them Frankfurt, Ireland, Paris, Stockholm and Zurich, and the customer decides which region telemetry is sent to. AWS offers a data processing addendum with EU standard contractual clauses for transfers. European organisations that want monitoring entirely outside US control can compare EU-headquartered or self-hosted options.
