<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>The Network Weathermap program, created by Howard Jones, works well
with the MRTG/RRD/Routers2 setup. When configuring, you need to specify
URLs for destination links ( ‘INFOURL’ ) and for obtaining popup
graphs ( ‘OVERLIBGRAPH’ ). Both of these URLs can be
generated for Routers by identifying the MRTG configuration file and the Target
name.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>In the example below, the configuration file is <b><span
style='font-weight:bold'>node1.cfg</span></b> and the Target name is <b><span
style='font-weight:bold'>node1_1</span></b>. The other options ensure
that we are looking at the Daily graph and (in the case of OVERLIBGRAPH) that
the image is created at the correct size.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Note how ‘page=image’ is used to retrieve just the graph
image without the surrounding HTML and frame set, and ‘xgtype=ds’
sets the graph to be ‘Daily Summary’ – that is, the Daily
graph as used in Summary pages, which does not have a legend and is smaller
sized.<o:p></o:p></span></font></p>
