==== What Is It? ====
----
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 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.


==== How To Install ====
----
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!


==== Notes ====
----

  * **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.
