Alibaba Cloud API Gateway provides the log management feature that is supported by Log Service. You can use this feature to ship API Gateway access logs to Log Service in real time. Log Service allows you to query, transform, and consume the data in real time. This topic describes the resources, billings, and limits that are related to the log management feature.

API Gateway provides the API hosting service to facilitate microservice aggregation, frontend and backend separation, and system integration. When you send an API request, an access log entry is generated. This log entry contains information such as the IP address of the API caller, request URL, response latency, response status code, and number of bytes of the request and response messages. You can use the log data to monitor the operating status of your web services.API Gateway
