>Multi Router Traffic Grapher (MRTG)</A

|

is a tool to monitor the traffic load on network-links. MRTG generates HTML pages
|
|
containing GIF images which provide a LIVE visual representation of this
|
|
traffic. MRTG is based on Perl and C and works under
|
|
<SPAN

|

<B

<B

In the first case, <B

|
CLASS="command"
|
|
>ntop</B
|
|
> displays the network
|
|
status on the user's terminal. In web mode a web browser (e.g.
|
|
netscape) can attach to <B
|
|
CLASS="command"
|
|
>ntop</B
|
|
> (that acts as a web
|
|
server) and get a dump of the network status. In the latter case,
|
|
<B
|
|
CLASS="command"
|
|
>ntop</B
|
|
> can be seen as a simple RMON-like agent with
|
|
an embedded web interface.
