Description
===========
RRD_ is a system to store and display time-series data (i.e. network
bandwidth, machine-room temperature, server load average).
.. _RRD: http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/
Options
=======
rrdtool.binary
path to the rrdtool binary
e.g.: ::
rrdtool.binary = "/usr/bin/rrdtool"
rrdtool.db-name
filename of the rrd-database. Make sure that <rrdtool.db-name> doesn't exist
before the first run, as lighttpd has to create the DB for you.
e.g.: ::
rrdtool.db-name = "/var/www/lighttpd.rrd"
