A ideia deste post é abordar algumas maneiras de fazer um gerenciamento out-of-band de uma aplicação. E a inspiração veio desta discussão sqlapi: library to connect to your erlang server via SQL: This library can help you to make an SQL server from your existing server. For example you have a server and let it be ejabberd. You want to give a list of connected users. Of course you will start from making HTTP endpoint that will reply with JSON with list of users.
