Start with x-pack/metricbeat/module/oracle/tablespace/data.go at lines 44-46 and inspect addDataFileData and its call path. Determine whether the referenced range variable can be observed by a goroutine, then leave the requested Bug, Mitigated, or Desirable Behavior reaction as the completion signal.
