This would only show immediate peers, i.e. next-hop peers. In a routed
configuration, it only gives you active router NIDs on clients and
servers.

At least on OSS, there's per-client stat somewhere under /proc -
I forgot the exact path, but should not be too hard to find(1) - e.g.
find /proc | grep a_client_nid.
