 ## The problem
 There is a plenty monitoring and observability service for cloud-scale application, such as StatsD, DataDog, Prometheus, and etc. Those services are great for monitoring, but require a lot of effort to posts every parts and setup properly, many people probably still confused how to extends their discord bots with those services.
