# AWS Lambda Telemetry

> Compare AWS Lambda ingestion options for function logs, platform logs, metrics, and traces to choose between CloudWatch, extensions, or the ADOT layer.

AWS Lambda emits function logs (your application output), platform logs (cold starts, timeouts, out-of-memory events), and — when instrumented — distributed traces. The right ingestion path depends on your runtime and whether you also want traces.

## Recommended method

[**ADOT Lambda Layer**](./aws-adot-lambda) — sends logs, metrics, and traces directly to Bronto over OTLP on supported runtimes. The signals generated automatically depend on the ADOT layer and instrumentation versions you deploy.

## Alternatives

* [**CloudWatch Log Forwarder**](./aws-client-cloudwatch) — captures Lambda's automatic `stdout` / `stderr` and works with runtimes the ADOT layer doesn't support (Ruby, custom runtimes).

See [Ingesting AWS Data into Bronto](./aws-overview) for the full service-to-method mapping.
