MRTG generates HTML pagescontaining GIF images which provide a LIVE visual representation ofthis traffic. Check <A HREF="http://www.ee.ethz.ch/stats/mrtg/">http://www.ee.ethz.ch/stats/mrtg/</A> for an example. MRTG is basedon Perl and C and works under UNIX and Windows NT. MRTG is being successfully used on many sites around the net.

These graphs are embeddedinto webpages which can be viewed from any modern Web-browser</P><P>In addition to a detailed daily view, MRTG also creates visualrepresentations of the traffic seen during the last seven days, thelast four weeks and the last twelve months. This is possible becauseMRTG keeps a log of all the data it has pulled from the router. Thislog is automatically consolidated, so that it does not grow over time,but still contains all the relevant data for all the traffic seen overthe last two years. This is all performed in an efficient manner.Therefore you can monitor 50 or more network links from any halfwaydecent UNIX box. </P><P>MRTG is not limited to monitoring traffic though, it is possible tomonitor any SNMP variable you choose. You can even use anexternal program to gather the data which should be monitored viaMRTG. People are using MRTG, to monitor things such as System Load,Login Sessions, Modem availability and more. MRTG even allows you toaccumulate two or more data sources into a single graph.</P></MULTICOL></TD></TR></TABLE><TABLE CELLSPACING=0 CELLPADDING=0 WIDTH=476><TR><TD><A NAME="HIGH"></A><TABLE WIDTH="100%" BGCOLOR=silver CELLSPACING=0 CELLPADDING=4><TR><TD><FONT COLOR=black SIZE="+2"><B>Highlights of MRTG</B></FONT></TD></TR></TABLE><OL> <LI>Works on most UNIX platforms and Windows NT</LI> <LI>Uses Perl for easy customization</LI> <LI>Has a highly portable SNMP implementation written entirely in Perl thanks to Simon Leinen.

Obviously everybody was interestedin knowing how the link was performing. So I wrote a quick hack whichcreated a constantly updated graph on the web, showing the trafficload on our Internet link. This eventually evolved into a ratherconfigurable Perl script called MRTG-1.0 which I released in spring1995. After a few updates I left my job at DMU, to start work at theSwiss Federal Institute of Technology. Due to lack of time I had toput MRTG aside. One day in January of 1996, I received email fromDave Rand asking if I had any ideas why MRTG was so slow. Actually Idid. MRTG's programming was not very efficient and it was writtenentirely in Perl. After a week or so, Dave wrote back to me and saidhe had tried what I had suggested for improving MRTG's speed. Since⌨️ 快捷键说明
