Amazon Bedrock AgentCore now delivers unified observability with traces and logs in a single log group

Amazon Bedrock AgentCore Unified Observability

Amazon Bedrock AgentCore now delivers agent traces and prompts to the same log group as your agent's logs, providing unified observability for AI agents in a single Amazon CloudWatch log group.

Previously, AgentCore split agent telemetry across multiple destinations, requiring debugging across multiple log groups. With this update, all telemetry traces, prompts, structured logs, and standard output are delivered to a single per-agent log group. This allows for easier correlation of traces and logs, fine-grained access control, and CMK encryption at the individual agent level.

What to do

• For new agents created after July 20, 2026, unified observability is enabled by default.
• For existing agents, set the `UNIFIED_TRACES_DESTINATION_ENABLED=true` environment variable and upgrade ADOT to version 0.17.1 or later.
