rrdgraph add-on is introduced from 4.1.9.

RRDtool is the OpenSource industry standard, high performance data logging and graphing system for time series data. Serverstats (http://serverstats.berlios.de/) is a simple tool(in PHP) for creating graphs using rrdtool

This add-on is Serverstats configured for litespeed. it can save years' real-time stats data of litespeed server and disply them in rrd graph at any time.

if your lsws is installed at /usr/local/lsws, to install the add-on:

#cd /usr/local/lsws/add-ons/rrdgraph
#./rrdgraph_install.sh

then follow the instruction … and that's it!

• rrdtool PATH

the php script assume rrdtool installed at /usr/bin/rrdtool, if your rrdtool installed in other location, for example /usr/local/cpanel/3rdparty/bin/rrdtool, please modify ls_stats/config/main.php,

change
'rrdtool' => '/usr/bin/rrdtool',
to
'rrdtool' => '/usr/local/cpanel/3rdparty/bin/rrdtool',

• change log method of cron job

default method is using syslog, you can change to other by modify ls_stats/config/log.php

• receving lots of emails from cron job

if the original cron job is:
* * * * * /path/to/lsphp5 /path/to/ls_stats/update.php
change to
* * * * * /path/to/lsphp5 /path/to/ls_stats/update.php >/dev/null

is recommended. this will redirect STDOUT only to /dev/null, but not STDERR. so if there is any error message to STDERR, e.g., “/path/to/lsphp5” is deleted for some reason, you'll receive an warning email from logwatch.
