Summary

Adds Dynamic Instrumentation to CloudWatch Application Signals, enabling live capture of variables, arguments, return values, and stack traces without restarting or redeploying applications.
Supported in Java, Python, and JavaScript/TypeScript via the ADOT SDKs; instrumentation is toggled with a flag and configured through the MCP server or CLI, with snapshots sent to CloudWatch Logs and correlated with traces.
Provides configurable data capture granularity and follows standard CloudWatch Logs ingestion and storage pricing.
