Overview
CLS manages its stored metric data by using Metric Topics and Logsets. A Metric Topic is the basic unit for collecting, storing, and querying metric data, while a Logset categorizes metric topics to help users manage them more easily. A Logset can contain both metric topics and log topics simultaneously. This document describes how to manage metric topics. Note:
The metric topics service ended its public beta on July 1, 2024, and is now officially a paid service. For more details, see the Billing Overview. Prerequisites
