Broker Service

Overview

The broker service provides an endpoint for storing logs in a mongodb back-end via the logger service. It accepts HTTP REST on port 8080 and uses gRPC on the back-end. In addition to this, it will expose custom metrics on an endpoint.

Getting started

• Spin up the stack by executing make up
• Create artificial load using hey command-line tool

• View documents via mongo-express client at http://localhost:8081
• See custom prometheus metrics by calling the /api/metrics endpoint
