This is an example project of how to use Jaeger tracing with the Echo framework. Tracing is used to provide observability within distributed systems. In this example, we have a proxy which routes requests either to the account service or the booking service. When a request is sent to the booking service it calls a login endpoint in the account service. It then sends the booking request to RabbitMQ. The batch service then reads from the message queue and sends a request to the account service. This can all be traced in Jaeger.
