| - | ==== What It Is ==== | ||
| - | ---- | ||
| - | 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. | ||
| - | |||
| - | |||
| - | ==== 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. | ||
