CloudWatch Metrics for Bring Your Own Containers

If the publish_cloudwatch_metrics value is Enabled in the Environment map in the /opt/ml/processing/processingjobconfig.json file, the container code emits Amazon CloudWatch metrics in this location: /opt/ml/output/metrics/cloudwatch.

The schema for this file is closely based on the CloudWatch PutMetrics API. The namespace is not specified here. It defaults to the following:

However, you can specify dimensions. We recommend you add the following dimensions at minimum:

The following JSON snippets show how to set your dimensions.

For a real-time endpoint, see the following JSON snippet which includes the Endpoint and MonitoringSchedule dimensions:

{ 
    "MetricName": "", # Required
    "Timestamp": "2019-11-26T03:00:00Z", # Required
    "Dimensions" : [{"Name":"Endpoint","Value":"endpoint_0"},{"Name":"MonitoringSchedule","Value":"schedule_0"}]
    "Value": Float,
    # Either the Value or the StatisticValues field can be populated and not both.
    "StatisticValues": {
        "SampleCount": Float,
        "Sum": Float,
        "Minimum": Float,
        "Maximum": Float
    },
    "Unit": "Count", # Optional
}

For a batch transform job, see the following JSON snippet which includes the MonitoringSchedule dimension:

{ 
    "MetricName": "", # Required
    "Timestamp": "2019-11-26T03:00:00Z", # Required
    "Dimensions" : [{"Name":"MonitoringSchedule","Value":"schedule_0"}]
    "Value": Float,
    # Either the Value or the StatisticValues field can be populated and not both.
    "StatisticValues": {
        "SampleCount": Float,
        "Sum": Float,
        "Minimum": Float,
        "Maximum": Float
    },
    "Unit": "Count", # Optional
