> Is RRDTool a rewrite of MRTG?
It's a rewrite of a portion of it. "Classic" MRTG has some limitations
in terms of scalability and flexibility. As it was originally designed to
count bits (or bytes) passing through an interface in two directions, it
doesn't like values less than 0, non-integer values, negative numbers,
or plotting a number of variables other then 2. Thus, using it for things
such as plotting temperature can get tricky. Also, classic MRTG draws a
new graph every interval, five minutes by default. This can impact server
performance if there are many inputs.
RRDTool (Round Robin Database Tool) allows for more flexibility in the
type of data being plotted, and also doesn't create the actual graphs
until they are requested by a web page "hit". This overcomes the limitations
of MRTG for plotting oddball or multiple values, etc. It is also more
server-friendly in terms of CPU usage provided that your graphs don't
become the Slashdot feature site and you wind up with an enormous number
of hits.
