Untuk menampilkan informasi tentang alarm-alarm yang terkait dengan sebuah metrik
Contoh berikut menggunakan
describe-alarms-for-metric
perintah untuk menampilkan informasi tentang alarm apa pun yang terkait dengan EC2 CPUUtilization metrik Amazon dan instance dengan ID i-0c986c72. :aws cloudwatch describe-alarms-for-metric --metric-name
CPUUtilization
--namespaceAWS/EC2
--dimensionsName=InstanceId,Value=i-0c986c72
