MetricFilterDimensionArgs

Specifies the CW metric dimensions to publish with this metric. Because dimensions are part of the unique identifier for a metric, whenever a unique dimension name/value pair is extracted from your logs, you are creating a new variation of that metric. For more information about publishing dimensions with metrics created by metric filters, see Publishing dimensions with metrics from values in JSON or space-delimited log events. 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 Charges.
