Pour publier une métrique personnalisée sur Amazon CloudWatch

L'exemple suivant utilise la put-metric-data commande pour publier une métrique personnalisée sur Amazon CloudWatch :

aws cloudwatch put-metric-data --namespace "Usage Metrics" --metric-data file://metric.json

Les valeurs de la métrique elle-même sont stockées dans le JSON fichiermetric.json.

Voici le contenu de ce fichier :

[
  {
    "MetricName": "New Posts",
    "Timestamp": "Wednesday, June 12, 2013 8:28:20 PM",
    "Value": 0.50,
    "Unit": "Count"
  }
]

Pour plus d'informations, consultez la section Publication de métriques personnalisées dans le manuel Amazon CloudWatch Developer Guide.
