# Azure Functions Telemetry

> Choose the right ingestion path for function execution logs, host logs, metrics, and distributed traces from Azure Functions — the OTel SDK or a Collector.

Azure Functions emits function execution logs (your code's output), host logs, and — when instrumented — distributed traces. The right ingestion path depends on whether you want application telemetry emitted directly from the function or the Function App's platform logs.

## Recommended method

[**OpenTelemetry SDK**](/opentelemetry/overview) — instrument the function and send logs, metrics, and traces to Bronto, either directly or through a [Collector](./azure-otel#self-managed-opentelemetry-collector).

## Alternatives

* [**Azure Monitor OpenTelemetry Distro**](./azure-monitor-otel-distro) — if you already use Application Insights, you can forward the same standard OTLP logs, metrics, and traces to Bronto.
* [**Azure Event Hub Forwarder**](./azure-client) — Function App logs streamed through Azure Monitor diagnostic settings are automatically assigned to a dedicated collection and dataset by the forwarder.

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