Untuk mendapatkan CPU pemanfaatan per instance EC2

Contoh berikut menggunakan get-metric-statistics perintah untuk mendapatkan CPU pemanfaatan untuk sebuah EC2 instance 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. Masing-masing dimensi ditentukan sebagai sebuah pasangan Nama/Nilai, yang menggunakan koma antara nama dan nilai tersebut. 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
