      Description

      Description:

      Added a new serverStatus metric named "repl.apply.batchSize" (https://docs.mongodb.com/manual/reference/command/serverStatus/#serverstatus.metrics.repl).

      Description:
      metrics.repl.apply.batchSize - The total number of oplog operations applied incremented at the oplog application batch boundaries whereas metrics.repl.apply.ops gets incremented after every operation.

      Engineering Ticket Description:

      repl.apply.ops is incremented for every op rather than at batch boundaries for the size of the entire batch so it's difficult to get a sense of the size of each batch. (https://docs.mongodb.com/manual/reference/command/serverStatus/#serverstatus.metrics.repl.apply.ops)
