Что такое RRD ?
При установке скрипта perl в описание продукта: You need to install rrdtool first Вопервых подскажите что делает данный продукт ? и Как его утановить ?
RDR это кольцевая база данных.

Цитата

RRD – это кольцевая база данных. Главная особенность данной БД заключается в том, что она всегда имеет фиксированный размер. То есть когда, будет достигнут конец в каком-нибудь поле в такой БД, то данные будут записываться в самое начало, тем самым, затирая предыдущие. В RRD вместо таблиц, колонок и полей вводятся другие понятия. В ней есть так называемые источники данных (DS), которые сами по себе ничего не хранят. Для простоты их можно интерпретировать как обычные колонки в таблице. Хранение же данных возлагается на кольцевые архивы (RRA). RRA привязывается к источнику данных и обладает такими свойствами как: количество ячеек; применяемая функция консолидации; интервал времени, после которого к данным применяется функция консолидации, и результат ее работы записывается в очередную ячейку. Пожалуй, это все, что требуется знать о структуре данных в RRD.

Установка RDR FreeBSD
Код
cd /usr/ports/databases/rrdtool
make config
make install clean


Установка RDR Linux
yum install rrdtool

Вот еще RedHat Linux
Install RRDTool on Red Hat Enterprise Linux

Q. I’ve downloaded RRDTool package called rrdtool-1.3.1.tar.gz. But ./configure command giving out lots of error messages. How do I install RRDTool on Red Hat Enterprise Linux 5.x – 64 bit version?

A. RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. It can be used either via simple wrapper scripts (from shell or Perl) or via frontends that poll network devices and put a friendly user interface on it.



Installing RRDTool on RHEL

In order to install RRDTool on Red Hat Enterprise Linux / CentOS Linux 64 bit version you need to install few development tools and libraries.

Step # 1: Install required dependencies

Login as root and type the following command:
# yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel

Step # 2: Download latest rrdtool tar ball

Type the following commands:
# cd /opt/
# wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz

Untar tar ball, enter:
# tar -zxvf rrdtool-1.3.1.tar.gz

Step #3: Compile and install rrdtool

You need to set PKG_CONFIG_PATH, enter:
# export PKG_CONFIG_PATH=/usr/lib/pkgconfig/

Type the following commands:
# ./configure

Sample output:

config.status: executing default-1 commands
config.status: executing intltool commands
config.status: executing default commands
config.status: executing po/stamp-it commands
checking in... and out again
ordering CD from http://tobi.oetiker.ch/wish .... just kidding ;-)

Config is DONE!
         With MMAP IO: yes
      Static programs: no
         Perl Modules: perl_piped perl_shared
          Perl Binary: /usr/bin/perl
         Perl Version: 5.8.8
         Perl Options: PREFIX=/usr/local/rrdtool-1.3.1 LIB=/usr/local/rrdtool-1.3.1/lib/perl/5.8.8
         Ruby Modules:
          Ruby Binary: no

Type 'make' to compile the software and use 'make install' to
install everything to: /usr/local/rrdtool-1.3.1.
      ... that wishlist is NO JOKE. If you find RRDtool useful
make me happy. Go to http://tobi.oetiker.ch/wish and
place an order.
                              -- Tobi Oetiker
----------------------------------------------------------------
Now compile and install RRDTool on RHEL:
# make
# make install
# cd /usr/local/
# ln -s rrdtool-1.3.1/ rrdtool/
# cd rrdtool
# ls -l

How do I verify my installation?
Now RRDtool is installed and ready to use. You can go to /usr/local/rrdtool/share/rrdtool/examples/ directory and run them to see if your installation has been successful or not:
# cd /usr/local/rrdtool/share/rrdtool/examples/
# ./stripes.pl
# ls -l
# cp stripes.png /var/www/html/

Fire a web browser and see a graph for yourself by typing the following url:
http://your-domain.com/stripes.png


(Fig.01: Sample RRDTool Graph)

Optional compile time settings
By default RRDTool will get installed at /usr/local/rrdtool-1.3.1/ directory. To change default installation directory use following command:
# ./configure --prefix=/usr/local/rrdtool
# make install

To see all compile configuration option enter:
# ./configure --help
