## 1. Apa itu structured logging di Laravel?

**Jawaban**

Structured logging adalah pencatatan data dalam format terstruktur (JSON, array) alih-alih teks biasa. Ini memudahkan pencarian, pemfilteran, dan analisis log dengan tool seperti Elasticsearch atau Datadog. Laravel menggunakan Monolog yang secara native mendukung structured logging melalui context dan processor.

## 2. Apa peran utama log channels di Laravel?

**Jawaban**

Log channels memungkinkan perutean log ke berbagai tujuan (file, Slack, Sentry) tergantung konteks. Dikonfigurasi di config/logging.php, channels memungkinkan misalnya mengirim error kritis ke Slack sambil tetap menyimpan log INFO di file lokal. Ini memberikan fleksibilitas maksimal untuk observability multi-tujuan.

## 3. Komponen Laravel mana yang menggunakan Monolog secara internal?

**Jawaban**

Laravel menggunakan Monolog sebagai mesin logging yang mendasari melalui facade Log dan service LogManager. Monolog adalah pustaka PHP standar yang menyediakan handler (file, Slack, Sentry), formatter (JSON, baris), dan processor (penambahan konteks). Laravel membungkusnya untuk menawarkan API yang sederhana dan ekspresif.
