Hello Ricardo,

    It has been a long time since I have seen polyrrd used...

We briefly document what polyrrd is on its man page. For example:
http://manpages.ubuntu.com/manpages/lucid/man1/polygraph-polyrrd.1.html

The tool requires a running udp2tcpd daemon, which is a part of the
runtime monitoring tool set:
http://manpages.ubuntu.com/manpages/lucid/man1/polygraph-udp2tcpd.1.html

You will need MRTG-like software to visualize data logged by polyrrd. We
do not provide such software, but others do.

Here is the corresponding change log entry (v2.6.0):

Most likely, modern test reports generated by polygraph-reporter contain
essentially the same information. If so, polyrrd's primary value is in
facilitating visualizing test information as the test runs (as opposed
to post-mortem analysis performed by polygraph-reporter).


HTH,
