During the lifetime of every user account, various events are generated and published to the application's message queue. It is advantageous to capture and persist these events to provide an audit log of an account's activity. In this article, we will build the AccountHistoryService which performs this task. In addition to capturing the account events, the service also provides a REST endpoint to query these events. After construction, we will deploy the application and exercise the generated Swagger interface. We then view the operational metrics using the AccountHistory Grafana dashboard.
