-
ingested_as_first_pipeline_in_bytesnumberrequired -
Total number of bytes of all documents ingested by the pipeline. This field is only present on pipelines which are the first to process a document. Thus, it is not present on pipelines which only serve as a final pipeline after a default pipeline, a pipeline run after a reroute processor, or pipelines in pipeline processors.
-
produced_as_first_pipeline_in_bytesnumberrequired -
Total number of bytes of all documents produced by the pipeline. This field is only present on pipelines which are the first to process a document.
