安装展示图形页面pnpnagios（rrdtool工具用来存储数据并画图，pnpnagios用来展示图形数据）
参考：http://docs.pnp4nagios.org/pnp-0.6/install
http://docs.pnp4nagios.org/pnp-0.6
tar xf pnp4nagios-0.6.25.tar.gz
cd pnp4nagios-0.6.25
yum install rrdtool rrdtool-perl -y
./configure
编译报错:
checking for Perl Module Time::HiRes... no
configure: error: Perl Module Time::HiRes not available
解决办法：
yum -y install perl-Time-HiRes
再次编译
./configure
make all
make install
make install-webconf
make install-config
make install-init
make fullinstall
安装后出现如下输出：
*** Configuration summary for pnp4nagios-0.6.25 03-01-2015 ***

type 'make all' to compile.
由于nagios采用的是4.1.1，pnp4nagios采用的是0.6.25
在官方文档有好几种配置pnp4nagios的模式，但是采用sync的模式会一直收集不到数据，而报错，于是改用了Bulk Mode with NPCD，成功出图，这里分析配置过程：
参考：http://www.aboutmonitoring.com/installing-nagios-core-4-pnp4nagios-check_mk-nagvis-centos-7-redhat-7/
1、编辑nagios.cfg文件，修改
process_performance_data=0将这个值改为1
##### Values: 1 = process performance data, 0 = do not process performance data
enable_environment_macros=1
2、然后去掉下面两个注释，使之启用：
#host_perfdata_command=process-host-perfdata
#service_perfdata_command=process-service-perfdata
然后在nagios.cfg配置文件中加入以下：
# service performance data
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file
#
# host performance data starting with Nagios 3.0
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file
各个文件的使用可以查看官方说明
3、修改commands.cfg
define command{
command_name process-service-perfdata-file
command_line /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$
}
define command{
command_name process-host-perfdata-file
command_line /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$
}
然后开启npcd服务：
/usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg
4、
[root@RS1 libexec]# /etc/init.d/nagios checkconfig
Running configuration check...
OK.
[root@RS1 libexec]# service httpd restart
停止 httpd： [确定]
正在启动 httpd：
[root@RS1 libexec]# /etc/init.d/nagios reload
Running configuration check...
Reloading nagios configuration...
done
5、浏览器访问
http://192.168.1.155/pnp4nagios/
出现报错：PHP GD extensionPHP GD extension not available
解决：
yum -y install php-gd
[root@RS1 libexec]# /etc/init.d/nagios checkconfig
Running configuration check...
OK.
[root@RS1 libexec]# service httpd restart
停止 httpd： [确定]
正在启动 httpd：
[root@RS1 libexec]# /etc/init.d/nagios reload
Running configuration check...
Reloading nagios configuration...
done
再看观察浏览器报错：
Your environment passed all requirements. Remove or rename the /usr/local/pnp4nagios/share/install.php file now.
解决办法：
mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php.ignore
以上只是解决了收集数据的功能，还必须在每一个host、service上展示相应的图形
设置如下：
编辑templates.cfg模板文件，创建host和service支持pnp4nagios功能：
define host {
name host-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
register 0
}
define service {
name srv-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}
定义完成之后，最后只需在定义的hosts、services配置文件中加入下操作：
define host{
use linux-server,host-pnp ; Name of host templates to use
; This host definition will inherit all variables that are defined
; in (or inherited by) the linux-server host template definition.
host_name localhost
alias localhost
address 127.0.0.1
}
define service{
use local-service,srv-pnp ; Name of service template to use
host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
于是整个配置工作完成，访问浏览器出图如下
至此结合图形展示成功
