## Peristiwa tindakan siklus hidup
Saat Anda menambahkan kait siklus hidup ke grup Penskalaan Otomatis, Amazon EC2 Auto Scaling mengirimkan peristiwa EventBridge ketika instance beralih ke status tunggu. Acara diproduksi atas dasar upaya terbaik.

### Scale-out tindakan siklus hidup
Contoh peristiwa berikut menunjukkan bahwa Amazon EC2 Auto Scaling memindahkan instance ke `Pending:Wait` status karena hook siklus hidup peluncuran.

}
}
```
### Scale-in tindakan siklus hidup
Contoh peristiwa berikut menunjukkan bahwa Amazon EC2 Auto Scaling memindahkan instance ke `Terminating:Wait` status karena kait siklus hidup penghentian.
**penting**
Ketika grup Penskalaan Otomatis mengembalikan instance ke kumpulan hangat sesuai skala, mengembalikan instance ke kolam hangat juga dapat menghasilkan `EC2 Instance-terminate Lifecycle Action` peristiwa. Peristiwa yang dikirimkan saat instance pindah ke status tunggu pada skala dalam memiliki `WarmPool` nilai untuk`Destination`. Untuk informasi selengkapnya, lihat [Instance reuse policy](ec2-auto-scaling-warm-pools.md#instance-reuse-policy).

### Acara scale-out yang sukses
Contoh peristiwa berikut menunjukkan bahwa Amazon EC2 Auto Scaling berhasil meluncurkan instans.

### Acara scale-in yang sukses
Contoh peristiwa berikut menunjukkan bahwa Amazon EC2 Auto Scaling berhasil menghentikan instans.
**penting**
Ketika grup Penskalaan Otomatis mengembalikan instance ke kumpulan hangat sesuai skala, mengembalikan instance ke kolam hangat juga dapat menghasilkan `EC2 Instance Terminate Successful` peristiwa. Peristiwa yang dikirimkan ketika instance berhasil kembali ke kolam hangat memiliki `WarmPool` nilai untuk`Destination`. Untuk informasi selengkapnya, lihat [Instance reuse policy](ec2-auto-scaling-warm-pools.md#instance-reuse-policy).

### Peristiwa penskalaan yang tidak berhasil
Contoh peristiwa berikut menunjukkan bahwa Amazon EC2 Auto Scaling gagal menghentikan instans.
**penting**
Ketika grup Penskalaan Otomatis mengembalikan instance ke kumpulan hangat sesuai skala, kegagalan mengembalikan instance ke kolam hangat juga dapat menghasilkan `EC2 Instance Terminate Unsuccessful` peristiwa.
