-From the Web Interface<br>+
--Click on the Administration Tab<br>+
--Mark "Enable" next to SNMP<br>+
--Click Submit<br>+
--Click Continue<br>+
--Fill in the information in the SNMP section that opened up.<br>+
-(Location, Contact, Name, RO Community, RW Community)<br>+

-There are a number of installation guides on the [http://people.ee.ethz.ch/~oetiker/webtools/mrtg/ MRTG website].<br>+
-In the guide, substitute:<br>+
-'''public''' for the ''RO Community'' you filled in earlier<br>+
-'''10.10.10.1''' with the Local IP address of your router.<br>+
- +
-===Windows===+
-You should have Windows IIS installed, or some other web server you're familiar with.+
-Substitute '''D:\InetPub\wwwroot\''' for the wwwroot of your IIS installation.+
- +
-Follow the guide at: http://people.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg-nt-guide.html+
- +
-Remove the line: WorkDir: c:\www\mrtg from the bottom of +
-Make the folder '''D:\InetPub\wwwroot\'''MRTG+
-Create a new virtual folder in IIS and point it to '''D:\InetPub\wwwroot\'''MRTG+
-Browse to http://127.0.0.1/MRTG to see your traffic logs.+

-Alternately for a quick look, use STG which will let you monitor 2 OIDs at a time.+

-* 8 (vlan1) - WAN traffic+
-* 9 (br0) - vlan0-eth1 bridge traffic+

Introduction

From the MRTG website:
The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network-links. MRTG generates HTML pages containing graphical images which provide a LIVE visual representation of this traffic. Check http://www.ee.ethz.ch/stats/mrtg/ for an example. MRTG is based on Perl and C and works under UNIX and Windows NT. MRTG is being successfully used on many sites around the net.
