This document explains how to configure MinIO server to log to different logging targets.

## Log Targets

MinIO supports currently two target types

- console
- http

### Logging Console Target

Console target is on always and cannot be disabled.

### Logging HTTP Target

Como esse código é executado antes de a aplicação **começar** a receber requisições e logo depois que ela **termina** de lidar com as requisições, ele cobre todo o **lifespan** da aplicação (a palavra "lifespan" será importante em um segundo 😉).
