Hi,
you are probably using the branch of the repository and not destiny. Take a
look at the first reply above, which explains that the monitoring component
is only on the Destiny branch, and how to get it.
(Using Destiny is suggested at this point, as it is more up-to-date version
of nox with several bug fixes and features. In any case, the example code in
"monitor" which you already looked at probably answers your question.)
