[mrtg] MRTG installation is DONE

[Lyle Giese]

The native MRTG setup uses rateup and stores the data in log files.  
Every 5 minutes, MRTG scans for data and then uses rateup to recreate 
ALL graphs.

With the RRD option, MRTG scans for data and stores the data in a 
different type of database called rrd or round-robin database.  No 
graphs are generated automatically.  This utilizes much less CPU and you 
can actually monitor more equipment this way.  But you still need to 
create graphs and that is where routers2 comes in.  It's referred to as 
a frontend to the MRTG rrd data.

When you convert to RRD, all your html pages and any webstuff referring 
to the old png graphs, have to call routers2.cgi to create the graphs on 
the fly.  Now the graphs are only re-created when needed.  Instead of 
all graphs being recreated every 5 minutes.  Much more CPU efficient.  
You can even run routers2 from a different computer now.
