fix: use aws-opentelemetry-distro and add input/output logging for LangGraph agent#552
Conversation
…ngGraph agent The LangGraph template was using the generic opentelemetry-distro which doesn't integrate properly with AWS X-Ray and CloudWatch. This resulted in only 1 span and no input/output logs in the runtime log group. Switch to aws-opentelemetry-distro (matching the Strands template) to enable proper AWS-native telemetry with botocore instrumentation that captures Bedrock model calls, tool usage, and trace context. Also add input/output logging to the agent entrypoint. Fixes #551
