Instrumentation to capture console logs as OTel logs

[martinkuba]

Is your feature request related to a problem? Please describe

This is a feature request to capture console logs and send them to OTLP backends using the OTel Logs API/SDK.

Describe the solution you'd like to see

User should be able to capture console logs and export them to OpenTelemetry backends.

Related to open-telemetry/opentelemetry-js-contrib#1558 and open-telemetry/opentelemetry-js-contrib#1559

This would be super useful, especially for capturing errors that occur before a backend application can detect them and forward on to the collector.

for now the only solution seems to be creating a dedicated app route for collecting frontend console.[] calls, right? 🥹

[martinkuba]

@el-buku If by app route you mean a custom backend endpoint for collecting the logs, you can collect the logs by sending them to a Collector or any OTLP backend that supports OTel logs. This instrumentation unfortunately still does not exist, but you can generate the logs manually using the Logs API and SDK.
