Here is first go at documenting this.
FAQ Entry.
Colors are used on several of the NTOP html pages to convey extra
information to the user. (in particular the ACTIVE TCP SESSIONS and the
LOCAL HOST STATS pages). There are 4(four) basic colors used to depict how
long the host has been active since it was first seen by NTOP.
The colors are as follows:
Age of Host Color Used HTML Color Code/description
-------------------------------------------------------------------
0-5 Minutes RED { color:#FF0000 }
5-15 Minutes Fuchsia/ Magenta { color:#FF00FF }
15-30 Minutes Coral { color:#FF7F00 } (light orange)
30-60 Minutes Slate Blue { color:#007FFF } (lighter less intense
blue)
60+ Minutes Blue { color:#0000FF }
The pages which display these colors use a html style sheet called
style.css located in html subdirectory where NTOP is installed. This style
sheet defines the following:
A.age0min { color:#FF0000 }
A.age5min { color:#FF00FF }
A.age15min { color:#FF7F00 }
A.age30min { color:#007FFF }
A.age60min { color:#0000FF }
Here is an abbreviated example of the HTML code produced by NTOP. Note the
value in the class= parameter. By looking at the HTML source code for the
generated page you can verify the color settings for each line. If you can
not see html source similar to below it is because you have the wrong frame
displayed or your browser doesn't support frames.
<TR ><TD ALIGN=RIGHT><A HREF="/10.10.10.1.html" class="age0min" (rest of
line cut for space)
<TR ><TD ALIGN=RIGHT><A HREF="/10.10.10.2.html" class="age5min" (rest of
