             Summary: Python SDK sending unexpected MonitoringInfo
                 Key: BEAM-9488
                 URL: https://issues.apache.org/jira/browse/BEAM-9488
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Ruoyun Huang


element_count metrics is supposed to be tied with pcollection ids, but by 
inspecting what is sent over by python sdk, we see there are monitoringInfo 
sent wit ptransforms in it. 

[Double checked the job graph, these seem to be redundant. i.e. the 
corresponding pcollection does have its own MonitoringInfo reported.]

Likely a bug. 

Proof: 

urn: "beam:metric:element_count:v1"
type: "beam:metrics:sum_int_64"
metric {
  counter_data {
    int64_value: 1
  }
}
labels {
  key: "PTRANSFORM"
  value: "start/MaybeReshuffle/Reshuffle/RemoveRandomKeys-ptransform-85"
}
labels {
  key: "TAG"
  value: "None"
}
