      MongoDB v6.0
      Replica set setup

      db.serverStatus().metrics.commands.aggregate value increments about every second on all nodes of the replica set on a system with no aggregations run by user.

      This behavior is different from version 5.3 and earlier versions.  We have tests where we expect the value to be 0 when no queries have been run, which fail now.
