d) 检查Provider和Consumer正常通信
继执行3.3步骤后，检查启动日志，查看consumer完成对provider服务的消费。
可以看到consumer pod日志输出如下（Triple协议被Envoy代理负载均衡）：
consumer istio-proxy日志输出如下：
可以看到provider pod日志输出如下：
provider istio-proxy日志输出如下：
e) 流量治理-VirtualService实现按比例流量转发
部署v2版本的demo provider
设置VirtualService与DestinationRule，观察流量按照4:1的比例分别被引导到provider v1与provider v2版本。
从消费端日志输出中，观察流量分布效果如下图：
