Laravel OpenTelemetry playground

This repository is inspired by https://github.com/open-telemetry/opentelemetry-php/blob/main/docs/laravel-quickstart.md It goes a bit deeper in defining spans and usage of OpenTelemetry tools in controllers

Google Cloud Traces&Logging

Create service account with permissions for writing logs and traces and create credentails for it. Download .json credentials and place them in storage/credentials.json. Check the .example.env for Google project environment variables.

If tracing and logging does not work the biggest chance is that credentials and permissions are not correctly set up. Currently hard to debug because tracer is instantiated outside Laravel scope. This implementation should be moved to Laravel lifecycle if possible.
