class Aws::CloudWatchLogs::Types::MetricTransformation
Indicates how to transform ingested log events to metric data in a CloudWatch metric.
@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 }
@!attribute [rw] metric_name
The name of the CloudWatch metric. @return [String]
@!attribute [rw] metric_namespace
A custom namespace to contain your metric in CloudWatch. Use namespaces to group together metrics that are similar. For more information, see [Namespaces][1]. [1]: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cloudwatch_concepts.html#Namespace @return [String]
@!attribute [rw] metric_value
The value to publish to the CloudWatch metric when a filter pattern matches a log event. @return [String]
@!attribute [rw] default_value
(Optional) The value to emit when a filter pattern does not match a log event. This value can be null. @return [Float]
@!attribute [rw] dimensions
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][1]. [1]: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/monitor_estimated_charges_with_cloudwatch.html @return [Hash<String,String>]
@!attribute [rw] unit
The unit to assign to the metric. If you omit this, the unit is set as `None`. @return [String]
