             Summary: Operator Topology and Metrics Inside Vertex
                 Key: FLINK-14136
                 URL: https://issues.apache.org/jira/browse/FLINK-14136
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Web Frontend
            Reporter: Yadong Xie

In the screenshot below, users can get vertex topology data in the job detail page, but the operator topology and metrics inside vertex is missing in the graph.

There are actually two operators in the first vertex, their names are Source: Custom Source and Timestamps/Watermarks, but users can only see Source: Custom Source -> Timestamps/Watermarks in the vertex level.

We can already get some metrics at the operator-level such as records-in and records-out from the metrics REST API (in the screenshot below).

If we can get the operators’ topology data inside a vertex, users can the whole operator topology with record-received and records-sent information after a glance at the graph, we think it would be quite useful to troubleshoot jobs’ problem when it is running. Here is a demo in the gif below.
