Установка Nagiosgraph в Unix/Linux

nagiosgraph — это утилита которая анализирует выходные и производительные данных из плагинов Nagios и хранит данные в RRD файлах. nagiosgraph создает диаграммы и генерирует HTML-страницы. И в своей статье «Установка Nagiosgraph в Unix/Linux» я расскажу как установить Nagiosgraph в Unix/Linux

Процесс установки и готовый скрипт приведен в статье:

Установка Nagios с nginx в CentOS

Установка Nagiosgraph в Unix/Linux

Можно установить данной ПО несколькими способами.

Для начала, устанавливаем все необходимые для работы библиотеки:

# yum install perl-GD php-gd rrdtool-perl rrdtool-php rrdtool perl-CGI perl-Time-HiRes perl-Nagios-Plugin perl-CPAN -y

И еще вот эти:

# cpan Nagios::Config -y && perl -MCPAN -e 'install Nagios::Config'  && perl -MCPAN -e 'install Module::Build'

Затем, переходим в нужный каталог и скачиваем nagiosgraph (на момент написание статьи — самая последняя версия данной утилиты),  так же, я распакую архив:

# cd /usr/local/src && wget http://jaist.dl.sourceforge.net/project/nagiosgraph/nagiosgraph/1.5.2/nagiosgraph-1.5.2.tar.gz && gunzip nagiosgraph-* && tar xvf nagiosgraph-*

Удалим ненужное:

# rm -f /usr/local/src/nagiosgraph-*.tar

1. Полу-автоматическом режиме.

Переходим в каталог и проверяем что все с конфигурацией нормально:

# cd nagiosgraph-* && ./install.pl --check-prereq

Вывод:

[root@localhost src]# cd /usr/local/src/nagiosgraph-* && ./install.pl --check-prereq

И выполняем установку:

# ./install.pl --layout overlay --install

  To complete the installation, do the following:

  * In the nagios configuration file (nagios.cfg),
    add these lines:

# process nagios performance data using nagiosgraph
process_performance_data=1
service_perfdata_file=/tmp/perfdata.log
service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=30
service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph


  * In the nagios commands file (command.cfg),
    add these lines:

# command to process nagios performance data for nagiosgraph
define command {
  command_name process-service-perfdata-for-nagiosgraph
  command_line /usr/local/nagios/libexec/insert.pl
}


  * In the apache configuration file (httpd.conf),
    add this line:

include /usr/local/nagios/etc/nagiosgraph/nagiosgraph-apache.conf

  * Check the nagios configuration:

/usr/local/nagios/bin/nagios -v /path/to/nagios.cfg

  * Restart nagios to start data collection:

/etc/init.d/nagios restart

  * Restart apache to enable display of graphs:

/etc/init.d/httpd restart

  * To enable graph links and mouseovers, see README sections:
       Displaying Per-Service and Per-Host Graph Icons and Links
       Displaying Graphs in Nagios Mouseovers

[root@localhost nagiosgraph-1.5.2]# 

В ходе установки, будут спрашивать что и куда установить.

2. Вручную.

После того как скачали и распаковали архив, все данные нужно раскидать (переместить ) в соответствующие папки. И так, начнем выполнение этого.

# mkdir -p /usr/local/nagios/etc/nagiosgraph

Скопируем конфиг-файлы:

# cp -r /usr/local/src/nagiosgraph-*/etc/* /usr/local/nagios/etc/nagiosgraph

Так же, скопируем остальные файлы:

# cp /usr/local/src/nagiosgraph-*/lib/insert.pl /usr/local/nagios/libexec
# cp /usr/local/src/nagiosgraph-*/cgi/*.cgi /usr/local/nagios/sbin/
# cp /usr/local/src/nagiosgraph-*/share/nagiosgraph.css /usr/local/nagios/share/stylesheets/
# cp /usr/local/src/nagiosgraph-*/share/nagiosgraph.js /usr/local/nagios/share/js
# cp /usr/local/src/nagiosgraph-*/share/nagiosgraph.ssi /usr/local/nagios/share/ssi/common-header.ssi
# mv /usr/local/nagios/share/images/action.gif /usr/local/nagios/share/images/action.gif_origin
# cp -i /usr/local/src/nagiosgraph-*/share/graph.gif /usr/local/nagios/share/images/action.gif
# cp /usr/local/src/nagiosgraph-*/share/nagiosgraph.ssi /usr/local/nagios/share/ssi/common-header.ssi

Отредактируем следующий конфиг-фал:

# vim /usr/local/nagios/etc/nagiosgraph/nagiosgraph.conf

И приводим к такому виду:

[...]
# Location of output from nagiosgraph data processing
logfile = /usr/local/nagios/var/nagiosgraph.log

# Location of output from nagiosgraph CGI scripts
cgilogfile = /usr/local/nagios/var/nagiosgraph-cgi.log

# Location of nagios performance data log file.
perflog = /usr/local/nagios/var/perfdata.log

# Directory in which to store RRD files
rrddir = /usr/local/nagios/var/rrd

# File containing regular expressions to identify service and perf data
mapfile = /usr/local/nagios/etc/nagiosgraph/map

# Nagiosgraph CGI URL.
nagiosgraphcgiurl = /nagios/cgi-bin

# Nagios CGI URL. If the Nagiosgraph CGI scripts are in a directory other
# than the Nagios CGI directory, then specify the Nagios CGI URL here.
#nagioscgiurl = /nagios/cgi-bin

# JavaScript: URL to the nagiosgraph javascript file.
javascript = /js/nagiosgraph.js

# Stylesheet: URL to the nagiosgraph stylesheet.
stylesheet = /stylesheets/nagiosgraph.css
[...]

Выставляем пермишены:

# chown nagios:nagios /usr/local/nagios/etc/nagiosgraph
# chown nagios:nagios /usr/local/nagios/sbin
# chown nagios:nagios /usr/local/nagios/libexec/insert.pl
# chown nagios:nagios /usr/local/nagios/share/stylesheets/nagiosgraph.css /usr/local/nagios/share/js/nagiosgraph.js
# chown nagios:nagios /usr/local/nagios/share/ssi/common-header.ssi

Создаем папку и назначаем права:

# mkdir /usr/local/nagios/var/rrd
# chown nagios:nginx /usr/local/nagios/var/rrd
# chmod 755 /usr/local/nagios/var/rrd

Откроем конфиг от nagios:

# vim  /usr/local/nagios/etc/nagios.cfg

И пропишем (я вставил в самый конец файла):

process_performance_data=1
service_perfdata_file=/usr/local/nagios/var/perfdata.log
service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=30
service_perfdata_file_processing_command=process-service-graph

Теперь, открываем:

# vim  /usr/local/nagios/etc/objects/commands.cfg

И пропишем:

define command {
command_name process-service-graph
command_line /usr/local/nagios/libexec/insert.pl
}

Проверяем:

# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Создаём файлы, каталоги, назначаем права:

# touch /usr/local/nagios/var/perfdata.log && touch /usr/local/nagios/var/nagiosgraph.log && touch /usr/local/nagios/var/nagiosgraph-cgi.log
# chmod 644 /usr/local/nagios/var/nagiosgraph.log
# chown nagios. /usr/local/nagios/var/nagiosgraph.log 
# chmod 644 /usr/local/nagios/var/nagiosgraph-cgi.log
# chown nginx /usr/local/nagios/var/nagiosgraph-cgi.log

Нужно  заменить путь к библиотекам:

sed -i -e "s/\/opt\/nagiosgraph\/etc/\/usr\/local\/nagios\/etc\/nagiosgraph/g" /usr/local/nagios/sbin/*.cgi
sed -i -e "s/\/opt\/nagiosgraph\/etc/\/usr\/local\/nagios\/etc\/nagiosgraph/g" /usr/local/nagios/libexec/insert.pl
sed -i -e "s/\/nagiosgraph\/nagiosgraph.js/\/js\/nagiosgraph.js/g" /usr/local/nagios/share/ssi/common-header.ssi

Открываем файл:

# vim /usr/local/nagios/etc/objects/templates.cfg

Нужно в этот файл( я вставил в самый конец файла) дописать проверку:

define service {
name graphed-service
action_url show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$' onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()' rel='showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w+450+-j
register 0
}

Теперь, открываем ваш хост (для примера взят  /usr/local/nagios/etc/objects/localhost.cfg) и прописываем(добавляем значение graphed-service):

define service{
 use local-service,graphed-service ; Name of service template to use
 host_name localhost
 service_description Swap Usage
 check_command check_local_swap!20!10
 }

PS: Между local-service,graphed-service не должно быть никаких пробелов!

Последние штрихи — открываем файл:

# vim /usr/local/nagios/share/side.php

Добавим ссылки на графики (в любом удобном для вас месте):

<ul>
<li><a href="/nagios/cgi-bin/show.cgi" target="main">Graphs</a></li>
<li><a href="/nagios/cgi-bin/showhost.cgi" target="main">Graphs by Host</a></li>
<li><a href="/nagios/cgi-bin/showservice.cgi" target="main">Graphs by Service</a></li>
<li><a href="/nagios/cgi-bin/showgroup.cgi" target="main">Graphs by Group</a></li>
</ul>

Перезагружаем нагиос:

# service nagios restart

Открываем свой браузер:

 http://YOUR_server_or_IP/nagios/cgi-bin/showconfig.cgi

PS: у меня будет использоваться вот так:

http://YOUR_server_or_IP/nagios/showconfig.cgi

И видим следующее:

Ругается что нет лог файлов, но я исправил это в своей статье и не стал переделывать рисунок. Для ленивых, вот готовая установка Nagiosgraph.

# cat Nagiosgraph.sh

Сам скрипт выглядит вот так:

# minute  hour mday month day who   command
   *        *    *    *     *  root  /usr/bin/perl /usr/local/nagios/libexec/insert.pl
