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.To learn more, visit the AWS documentation.
