Linkerd not displaying count of requests, success and failure rates

Question

I am new to linkerd and trying to proxy all the requests to my microservices via linkerd and with file based service discovery. I was able to do it successfully and the requests successfully got registered with the admin dashboard running on port 9990.

But my problem is the dashboard always shows N/A for the success rate and failure rate. It becomes 100% for just a sec the request is received and again goes back to N/A. But I want to keep track of all my request via linkerd i.e I want linkerd to remember the number of requests and the successrate and failure rate.

Here is the screenshot of my problem

Linkerd community forum回答了这个问题。为了完整起见，在这里添加答案：

  

仪表板提供当前正在进行的快照 - 它每秒轮询/admin/metrics.json并显示当时的指标（因此在那一刻，有多少请求，重试，待处理请求，所以如果那一刻没有任何事情发生，那些统计数据将是0）。对于指标的长期视图，您还需要其他内容（有关收集指标的详细信息，请参阅https://linkerd.io/getting-started/admin/index.html#metrics）。

     

如果您使用的是Kubernetes或DC / OS，还可以查看linkerd-viz。希望有所帮助！
