#### [ CLI ]
**AWS CLI**
**Cara mendapatkan pemanfaatan CPU per instans EC2**
Contoh berikut menggunakan perintah `get-metric-statistics` untuk mendapatkan pemanfaatan CPU untuk instans EC2 dengan ID i-abcdef.
```
aws cloudwatch get-metric-statistics --metric-name CPUUtilization --start-time 2014-04-08T23:18:00Z --end-time 2014-04-09T23:18:00Z --period 3600 --namespace AWS/EC2 --statistics Maximum --dimensions Name=InstanceId,Value=i-abcdef
```
Output:
```

**Menentukan beberapa dimensi**
Contoh berikut menggambarkan cara menentukan beberapa dimensi. Setiap dimensi ditentukan sebagai Name/Value pasangan, dengan koma antara nama dan nilainya. Beberapa dimensi dipisahkan dengan satu spasi. Jika sebuah metrik mencakup beberapa dimensi, Anda harus menetapkan sebuah nilai untuk masing-masing dimensi yang ditetapkan.
Untuk contoh lainnya menggunakan `get-metric-statistics` perintah, lihat Mendapatkan Statistik untuk Metrik di *Panduan CloudWatch Pengembang Amazon*.
```
aws cloudwatch get-metric-statistics --metric-name Buffers --namespace MyNameSpace --dimensions Name=InstanceID,Value=i-abcdef Name=InstanceType,Value=m1.small --start-time 2016-10-15T04:00:00Z --end-time 2016-10-19T07:00:00Z --statistics Average --period 60
