     "Nyx monitors the performance of relays participating in the
@uref{https://www.torproject.org/, Tor anonymity network}.  It displays this
information visually and in real time, using a curses-based terminal interface.
This makes Nyx well-suited for remote shell connections and servers without a
graphical display.  It's like @command{top} for Tor, providing detailed
statistics and status reports on:

@enumerate
@item connections (with IP address, hostname, fingerprint, and consensus data),
@item bandwidth, processor, and memory usage,
@item the relay's current configuration,
@item logged events,
@item and much more.
@end enumerate

Potential client and exit connections are scrubbed of sensitive information.")
