监测mysql查询时间

public Organization getOrg
            (String organizationId) {
        Span newSpan = tracer.createSpan("getOrgDBCall");//创建一个新的自定义跨度，名为getOrgDBCall

        }
        finally{
          newSpan.tag("peer.service", "mysql");//将标签信息添加到跨度中，提供了将要被Zipkin捕获的服务名称
          newSpan.logEvent(org.springframework.cloud.sleuth.Span.CLIENT_RECV);//记录事件，告诉Spring Cloud Sleuth捕获调用完成的时间
          tracer.close(newSpan);//关闭跟踪，否则报错
