All

This processor parses log events that are in JSON format. It can extract JSON key-value pairs and place them under a destination that you specify.

Additionally, because you must have at least one parse-type processor in a transformer, you can use ParseJSON as that processor for JSON-format logs, so that you can also apply other processors, such as mutate processors, to these logs.

For more information about this processor including examples, see parseJSON in the CloudWatch Logs User Guide.
