Configure the features of generating and collecting the access logs of an ASM gateway - Alibaba Cloud Service Mesh

You can separately configure the features of generating and collecting the access logs of a Service Mesh (ASM) gateway based on your business requirements. If you enable the feature of generating the access logs of an ASM gateway, the gateway prints the access logs to the standard output. You can customize the fields that are printed in the access logs. If you enable the feature of collecting the access logs of an ASM gateway, the logs printed by the gateway are collected to Simple Log Service of Alibaba Cloud, which allows you to store and analyze logs and visualize the query and analysis results on charts. This topic describes how to configure the features of generating and collecting the access logs of an ASM gateway and view the access logs.
