编辑/etc/services添加NRPE daemon
nrpe 5666/tcp # NRPE

cd nagiosgraph-1.5.2
perl install.pl --check-prereq

./install.pl --layout overlay --prefix/usr/local/nagios
（配置路径部分均选择/usr/local/nagios）
vi share/nagiosgraph.ssi
src="/nagiosgraph/nagiosgraph.js" to src="/nagios/nagiosgraph.js"
cp share/nagiosgraph.ssi/usr/local/nagios/share/ssi/common-header.ssi
编辑Nagiosgraphp配置文件，确保一下参数路径
vi/usr/local/nagios/etc/nagiosgraph/nagiosgraph.conf
perflog =/usr/local/nagios/var/perfdata.log
rrddir = /usr/local/nagios/var/rrd
mapfile =/usr/local/nagios/etc/nagiosgraph/map
nagiosgraphcgiurl = /nagios/cgi-bin
javascript =/nagios/nagiosgraph.js
stylesheet =/nagios/nagiosgraph.css
logfile =/usr/local/nagios/var/nagiosgraph.log
cgilogfile =/usr/local/nagios/var/nagiosgraph-cgi.log
调整以下文件所属用户
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/nagiosgraph.css /usr/local/nagios/share/nagiosgraph.js
chown nagios:nagios/usr/local/nagios/share/ssi/common-header.ssi
创建RRD目录，并设置以下权限
mkdir /usr/local/nagios/var/rrd
chmod nagios:apache/usr/local/nagios/var/rrd
chmod 755 /usr/local/nagios/var/rrd
创建nagiosgraph.log nagiosgraph-cgi.log文件（有就不必创建），并调整权限
touch /usr/local/nagios/var/nagiosgraph.log
chown nagios/usr/local/nagios/var/nagiosgraph.log
chmod 644/usr/local/nagios/var/nagiosgraph.log
touch/usr/local/nagios/var/nagiosgraph-cgi.log
chown apache/usr/local/nagios/var/nagiosgraph-cgi.log
chmod 644/usr/local/nagios/var/nagiosgraph-cgi.log
编辑/usr/local/nagios/share/side.php在 ‘Trends’ heading下添加:
<li><ahref="<?php echo $cfg["cgi_base_url"];?>/trends.cgi"target="<?php echo $link_target;?>">Trends</a>
<ul>
<li><ahref="<?php echo $cfg["cgi_base_url"];?>/show.cgi"target="<?php echo$link_target;?>">Graphs</a></li>
<li><ahref="<?php echo$cfg["cgi_base_url"];?>/showhost.cgi" target="<?phpecho $link_target;?>">Graphs by Host</a></li>
<li><ahref="<?php echo$cfg["cgi_base_url"];?>/showservice.cgi"target="<?php echo $link_target;?>">Graphs byService</a></li>
<li><ahref="<?php echo$cfg["cgi_base_url"];?>/showgroup.cgi" target="<?phpecho $link_target;?>">Graphs by Group</a></li>
</ul>
</li>
验证配置并重启nagios
/usr/local/nagios/bin/nagios -v/usr/local/nagios/etc/nagios.cfg
/etc/init.d/nagios restart
验证nagiosgraphconfiguration
http://localhost/nagios/cgi-bin/showconfig.cgi
或者
http://Server-IP-Address/nagios/cgi-bin/showconfig.cgi
验证ok ，抓取一些数据，看看图形效果
http://localhost/nagios/cgi-bin/show.cgi
或者
http://Server-IP-Address/nagios/cgi-bin/show.cgi
Now we need to definean action URL for the services that we want to graph, so that you can click togo directly to the graphs for that service from the Nagios Core web interface.
编辑/usr/local/nagios/etc/objects/templates.cfg，添加graph URL service，以便直接在 web上点击链接。
define service {
name graphed-service
action_url /nagiosgraph/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$'onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()'rel='/nagiosgraph/cgi-bin/showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w+450+-j
register 0
}
服务用法示范
define service {
use generic-service,graphed-service
host_name web001
service_description PING
check_commandcheck_ping!100,10%!200,20%
}
/usr/local/nagios/bin/nagios -v/usr/local/nagios/etc/nagios.cfg
/etc/init.d/nagios reload

cp /usr/local/src/nagios/nagios-4.1.1/sample-config/mrtg.cfg/usr/local/nagios/etc/
mkdir -p/usr/local/nagios/share/stats
vim/usr/local/nagios/etc/mrtg.cfg，在前面添加
WorkDir:/usr/local/nagios/share/stats
初始化
env /usr/bin/mrtg/usr/local/nagios/etc/mrtg.cfg
创建HTML页面
/usr/bin/indexmaker/usr/local/nagios/etc/mrtg.cfg--output=/usr/local/nagios/share/stats/index.html
配置定时任务
vim/etc/cron.d/mrtg-nagios
Add thefollowing:
*/5 * * * * root env /usr/bin/mrtg /usr/local/nagios/etc/mrtg.cfg
You can nownavigate to https://example.org/nagios/stats/ to see the graphs.
编辑 sidebar file:
vim/usr/local/nagios/share/side.php
And add thefollowing somewhere in the menu:
<divclass="navsection">
<divclass="navsectiontitle">Extra Tools</div>
<divclass="navsectionlinks">
<ulclass="navsectionlinks">
<li><ahref="/nagios/stats" target="<?php echo$link_target;?>">MRTG stats</a></li>
<li><ahref="/nagiosgraph/cgi-bin/show.cgi" target="<?php echo$link_target;?>">Nagios Graph</a></li>
</ul>
</div>
</div>
</div>
hosts.cfg
hostgroups.cfg
service-test.cfg
servicegroups.cfg
重点强调templates.cfg commands.cfg
vim templates.cfg添加
define service {
name graphed-service
action_url /nagiosgraph/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$'onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()'rel='/nagiosgraph/cgi-bin/showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w+450+-j
register 0
}
vim commands.cfg
define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H$HOSTADDRESS$ -c $ARG1$ -t 120
}
由于整理资料费时，配置文件配置可参考/usr/local/nagios/etc/object/localhost.cfg,这里不细写 安装过程有其他问题google一下。
参考文件有官网的Installing_Nagios_Core_From_Source.pdf 、NRPE.pdf、安装nagiosgraph.txt和Nagios网络监控中文版.pdf
