# Cuplikan templat Amazon CloudWatch Log
Amazon CloudWatch Logs dapat memantau sistem, aplikasi, dan file log kustom Anda dari instans Amazon EC2 atau sumber lain. Anda dapat menggunakan CloudFormation untuk menyediakan dan mengelola grup log dan filter metrik. Untuk informasi selengkapnya tentang CloudWatch Log Amazon, lihat [Panduan Pengguna CloudWatch Log Amazon](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html).

## Kirim CloudWatch log ke Log dari instance Linux
Template berikut menunjukkan cara mengatur server web di Amazon Linux 2023 dengan integrasi CloudWatch Log. Template melakukan tugas-tugas berikut:
+ Menginstal Apache dan PHP.
+ Mengkonfigurasi CloudWatch agen untuk meneruskan log akses Apache ke CloudWatch Log.
+ Menyiapkan peran IAM untuk memungkinkan CloudWatch agen mengirim data log ke CloudWatch Log.
+ Membuat alarm dan notifikasi khusus untuk memantau kesalahan 404 atau penggunaan bandwidth tinggi.
Peristiwa log dari server web menyediakan data metrik untuk CloudWatch alarm. Dua filter metrik menjelaskan bagaimana informasi log diubah menjadi CloudWatch metrik. Metrik 404 menghitung jumlah kejadian 404. Metrik ukuran melacak ukuran permintaan. Kedua CloudWatch alarm akan mengirimkan pemberitahuan jika ada lebih dari dua 404 dalam waktu 2 menit atau jika ukuran permintaan rata-rata lebih dari 3500 KB selama 10 menit.

## Kirim CloudWatch log ke Log dari instance Windows
Template berikut mengkonfigurasi CloudWatch Log untuk instance Windows 2012R2.
Agen CloudWatch Log di Windows (agen SSM di Windows 2012R2 dan Windows 2016 AMIs) hanya mengirim log setelah dimulai, jadi log apa pun yang dihasilkan sebelum startup tidak dikirim. Untuk mengatasi ini, templat membantu untuk memastikan agar agen dimulai sebelum log ditulis oleh:
+ Pengonfigurasian penyiapan agen sebagai item `config` yang pertama dalam `configSets` cfn-init.
+ Penggunaan `waitAfterCompletion` untuk menyisipkan jeda setelah perintah yang memulai agen.
