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.
