> When constructing a proxy for remote peer to perform a RPC, DNS resolution is performed.  It would be great to add metrics to measure how much time the DNS resolution takes.  That information could be provided by :
> * a histogram for DNS resolver times
> * 'standard' cache metrics for the DNS resolver cache
