看官方文档有这么一句话:Service Selector provides 2 level selectors, service group list and service name list. The group name is separated from the service name if it follows <group name>::<logic name> format. Topology map is available for single group, single service, or global(include all services).

意思是说：分组是一种服务名的命名规则：<group name>::<logic name>

例如: export SKYWALKING__SERVICENAME=dev::svc-user
