问题描述
在此文档 A short introduction to Channelz 中，有一个名为 grpc-zpages 的网络工具可以方便地通过网页提供 channelz 数据。
但是，我们无法从此网络工具中找到任何 <script src="https://cdn.plot.ly/plotly-2.1.0.min.js"></script>

<div id="tester" style="width:600px;height:250px;"></div> 数据。有人遇到同样的问题吗？
为了运行这个网络工具，需要对代码进行一些更改
zprox.sh解决错误 function envoy_on_response(response_handle)
filter_name = "ENVOY"
response_handle:headers():add("my_Filter",filter_name)
end
-
注释
envoy_on_response() function not found. lua filter will not hook responses的network_mode: 'host'以解决错误start_docker.sh -
用
替换docker.errors.InvalidArgument: "host" network_mode is incompatible with port_bindings
manual.GenerateAndRegisterManualResolver()在 r := manual.NewBuilderWithScheme("whatever")
r.InitialState(resolver.State{Addresses: []resolver.Address{{Addr: ":10001"},{Addr: ":10002"},{Addr: ":10003"}}})
// Set up a connection to the server.
conn,err := grpc.Dial(r.Scheme()+":///test.server",grpc.WithInsecure(),grpc.WithResolvers(r),grpc.WithDefaultServiceConfig(`{"loadBalancingPolicy":"round_robin"}`),)
下
解决方法
请确保您已将 channelz 服务和反射服务添加到服务器。如果你的服务是一个客户端，你需要让客户端也有一个 grpc 服务器。调用服务器与通道连接后，即可获取相关数据。
grpc-zpages 不维护了，用起来很不方便。我建议使用 channelzcli 替换。
