In addition to
time_since_last_handshake
, expose atime_since_last_received
. This is useful to know downstream because it allows applications to react to connectivity problems. Keepalive packets will update this timer. As soon as this duration is > than the configured keep-alive (of the remote), we know that there is a connectivity problem.
