Hi, community: We know there are three important parts of observability with modern distributed system: logging, metric and tracing. The tracing feature for observability in ShardingSphere components, logging feature is easy to gain via some tools such like ELK.And it's the time to design and implement metrics feature now. Finally we get a complete observability with UI console(integration with promethus/grafana). So we will launch this mission for the certain tasks about metrics. @yu199195 will be in charge of them.
Any ideas and questions are welcome here.
