      Description

      When trying to run mongoreplay monitor against a 3-node replica set running version r3.6.4-rc0, hash: 4c5a017, I see the following error messages in the message logs when trying to monitor the traffic on the primary:

      Certain message types appear to display properly, like isMaster, but other, internal replica set messages do not i.e. replSetUpdatePosition. I am running this on Ubuntu Linux 16.10, with version f5c4a44 of mongo-tools.

      The exact command line invocation used:

      ./bin/mongoreplay monitor -i lo -e "port 42310"
