Application Signals provides OTEL support via X-Ray OTLP endpoint for traces

CloudWatch Application Signals, an application performance monitoring (APM) solution, enables developers and operators to easily monitor the health and performance of their applications hosted across different compute platforms such as EKS, ECS and more. Customers can now use OpenTelemetry Protocol (OTLP), an open-source protocol, to send traces to the X-Ray OTLP endpoint, and unlock application performance monitoring capabilities with Application Signals.

OpenTelemetry Protocol (OTLP) is a standardized protocol for transmitting telemetry data from your applications to monitoring solutions like CloudWatch. Developers who use OpenTelemetry to instrument their applications can now send traces to the X-Ray OTLP endpoint, unlocking, via Application Signals, pre-built, standardized dashboards for critical application metrics (throughput/latency/errors), correlated trace spans, and interactions between applications and its dependencies (such as other AWS services). This provides operators with a complete picture of the application's health, allowing them to pinpoint the source of performance issues. By creating Service Level Objectives (SLOs) within Application Signals, customers can track performance indicators of crucial application functions. This makes it simple to spot and address any operations falling short of their business goals. Finally, customers can also analyze application issues in business context such as troubleshoot customer support tickets or find top customers impacted due to application disruptions by searching and analyzing transaction (or trace) spans.

OTLP endpoint for traces is available in all regions where Application Signals is generally available. For pricing, see Amazon CloudWatch pricing. See documentation to learn more.
