AWS Distro for OpenTelemetry vs syslog-ng

AWS Distro for OpenTelemetry (ADOT) collects logs, metrics, and traces, with options to send correlated telemetry to one or more observability backends. Applications can be instrumented once, and auto-instrumentation can generate traces without changes to application code. ADOT also gathers metadata from AWS resources and managed services to connect application performance data with infrastructure information. Documented destinations include Amazon Managed Service for Prometheus, Amazon CloudWatch, AWS X-Ray, Amazon OpenSearch, OTLP-compliant backends, and Amazon MSK. It supports workloads on AWS App Runner, Lambda, EC2, ECS, EKS on EC2, Fargate, and on-premises datacenters. Getting-started guides cover Go, Java, JavaScript, Python, Ruby, .NET, PHP, and Android. The project describes ADOT as backed by AWS Support, testing, and certification, and says it contributes changes and fixes to the OpenTelemetry community. ADOT is free and supports cloud and self-hosted deployment. The download page lists Collector version 0.50.0, released August 25, 2026, under the Apache-2.0 license.
