 Description   

At startup we log the replica set config, which generally is specified in terms of hostnames.
Whenever we accept a new connection, we log the IP address that the connection came in on.

It would be nice to have a way to correlate incoming connections to what replica set member they came from. If at startup we printed the IP address(es) that we can resolve the hostname to, that could give us additional information that would be useful when reading customer log files.

Closing because SERVER-35540 is a better approach.

I opened SERVER-35540 to track possible work in moving more of our logging towards HostAndPort's, rather than in transport layer specific primitives.

mira.carey@mongodb.com, then can you just point us towards what we should use to get the resolved IP address from the hostname?

spencer we think this is a replication feature - bouncing back to you to triage.
