Overview

Note:

When making an API call, you may pass MetricTransformation data as a hash:

{
  metric_name: "MetricName", # required
  metric_namespace: "MetricNamespace", # required
  metric_value: "MetricValue", # required
  default_value: 1.0,
  dimensions: {
    "DimensionsKey" => "DimensionsValue",
  },
  unit: "Seconds", # accepts Seconds, Microseconds, Milliseconds, Bytes, Kilobytes, Megabytes, Gigabytes, Terabytes, Bits, Kilobits, Megabits, Gigabits, Terabits, Percent, Count, Bytes/Second, Kilobytes/Second, Megabytes/Second, Gigabytes/Second, Terabytes/Second, Bits/Second, Kilobits/Second, Megabits/Second, Gigabits/Second, Terabits/Second, Count/Second, None
}

Indicates how to transform ingested log events to metric data in a CloudWatch metric.

#default_valueFloat

(Optional) The value to emit when a filter pattern does not match a log event. This value can be null.

Returns:

  • (Float)

  SENSITIVE = []
  include Aws::Structure
end

#dimensionsHash<String,String>

The fields to use as dimensions for the metric. One metric filter can include as many as three dimensions.

Metrics extracted from log events are charged as custom metrics. To prevent unexpected high charges, do not specify high-cardinality fields such as `IPAddress` or `requestID` as dimensions. Each different value found for a dimension is treated as a separate metric and accrues charges as a separate custom metric.

To help prevent accidental high charges, Amazon disables a metric

filter if it generates 1000 different name/value pairs for the dimensions that you have specified within a certain amount of time.

You can also set up a billing alarm to alert you if your charges

are higher than expected. For more information, see [ Creating a Billing Alarm to Monitor Your Estimated Amazon Web Services Charges].

Returns:

  • (Hash<String,String>)
