Need minor improvement in mongodump logging capability. It will be good if mongodump log has details of mongod instance from which it is currently reading data from directly.

This would be convenient in debugging any performance related problems between mongodump tool and the servers. Currently users have to check mongod logs of each of the servers to come to conclusion from which server mongodump is actually reading.
It will be good if this information can be logged in the mongodump log possibly at -vvvvv level.

Thank you in advance.

Update: need to do the same for mongoexport as well
