Hi Dan This seem to be a known issue [1], and which is now tracked in [2].
As a whole, now the record sent only shows the records sent by the "last" operator in the chain, thus if there are chained sideoutput, the number of records in main output would be overriden.

Even though the main output of the operator goes to another operator, the "Records Sent" metric is still zero. I'd expect it to be the number of records of the main output (not the side sink operators). Is this a known issue? [Screen Shot 2022-03-17 at 3.04.04 PM.png]
