\textbf{Report Submission Deadline: Thursday 8 August 2002}
\vspace{2ex}

Your task is to create a web-based system that monitors broadcast and
multicast network traffic using Cricket and \SNMP.  You are required
to provide monitoring of the following:
\begin{itemize}
\item monitor incoming and outgoing network traffic on \emph{all network
  interfaces} of your computer;
\item monitor incoming and outgoing traffic which is \emph{not
    unicast} on \emph{all network interfaces} of your computer.
\end{itemize}
All network traffic is to be monitored in units of \emph{bits per
  second}.  Kilobits or megabits per second are okay.  One kilobit per
second is $2^{10}$ bits per second; one megabit per second is $2^{20}$
bits per second.

You are required to submit a report showing screenshots of your work,
including a hard copy of the Cricket setup that you wrote to achieve
this, and a written description of how it works.  At least one of your
screenshots should show a short-term graph with at least six hours of
data collected by your system.

To do this, you will need to have the agent running on your machine,
configured with access to the Mib-2 tree.  You should have done this
already; the process is described in the handout entitled \emph{SNMP
  Agent and the Set Operation}\@.

For each of the two variables you monitor, you should provide:
\begin{itemize}
\item at least one set of graphs, monitoring the data over a daily,
  weekly, monthly and annual basis;
\item meaningful labels to the graphs; for example, the graph for
  Internet network traffic should be labelled something like:
  ``Internet network traffic'' rather than as ``\texttt{3}'' or
  ``\texttt{ppp0}''.  The axes of the graphs should also be labelled
  properly.
\item meaningful names on the links to the graphs.
\end{itemize}
For each network interface, there should be one set of graphs for the
broadcast and multicast data, and another set for the total network
traffic.

Note that the Net-\SNMP agent does not implement the deprecated
\texttt{ifInNUcastPkts} or \texttt{ifOutNUcastPkts} managed objects in
the \texttt{mib-2} \texttt{ifTable}.  To implement the requirement for
monitoring non-unicast network traffic, you will need Cricket to
perform some arithmetic with the data from the available managed
objects in the \texttt{mib-2} \texttt{ifTable}.

Please note that I have revised the first Cricket document quite a
lot, with some useful description of the way that Cricket works, and
its configuration.  It is available at
\url{http://ictlab.tyict.vtc.edu.hk/snm/lab/cricket/cricket.pdf} and
\url{http://sysadmin.no-ip.com/snm/lab/cricket/cricket.pdf}.

You should be able to explain what you did and why.  Your work must be
original.
