'Unexpected field for mongos collStats' is filling our logs for no reason

I’m running Mongos 5.0.3 in a cluster and we have log issues with these things:

..."Unexpected field for mongos collStats","attr":{"fieldName":"$topologyTime"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"operationTime"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"freeStorageSize"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"indexBuilds"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"scaleFactor"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"$gleStats"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"lastCommittedOpTime"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"$configServerState"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"$clusterTime"}...
..."Unexpected field for mongos collStats","attr":{"fieldName":"$configTime"}...

Looking at the source code for 5.0.3 I can indeed not find these fields.

I know very little about the ins and outs of MongoS itself, so I have to ask:

  1. Why is this beeing logged?

  2. Can I configure MongoS to not log these? Clear out log id “22749” please :smiley:

  3. What initiates this functionality - is it something I can configure?
