Untuk mempublikasikan metrik khusus ke Amazon CloudWatch
Contoh berikut menggunakan
put-metric-data
perintah untuk menerbitkan metrik kustom ke Amazon CloudWatch:aws cloudwatch put-metric-data --namespace
"Usage Metrics"
--metric-datafile://metric.json
Nilai untuk metrik itu sendiri disimpan dalam JSON file,
metric.json
.Berikut adalah isi dari file tersebut:
[ { "MetricName": "New Posts", "Timestamp": "Wednesday, June 12, 2013 8:28:20 PM", "Value": 0.50, "Unit": "Count" } ]
Untuk informasi selengkapnya, lihat Menerbitkan Metrik Kustom di Panduan CloudWatch Pengembang Amazon.
Cara menentukan beberapa dimensi
Contoh berikut menggambarkan cara menentukan beberapa dimensi. Masing-masing dimensi ditentukan sebagai sebuah pasangan Name=Value. Beberapa dimensi dipisahkan menggunakan koma.:
aws cloudwatch put-metric-data --metric-name

--namespaceMyNameSpace
--unitBytes
