Description
|
||
|
|
===========
|
||
|
|
|
||
|
|
RRD_ is a system to store and display time-series data (i.e. network
|
||
|
|
bandwidth, machine-room temperature, server load average).

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 exists
|
||
|
|
before the first run as lighttpd has to create the DB for you.
|
||
|
|
|
||
|
|
e.g.: ::
|
||
|
|
|
||
|
|
rrdtool.db-name = "/var/www/lighttpd.rrd"
