版本说明：系统CentOS6.5 64位  nagios-4.0.5 nagios-plugins-2.0 nrpe-2.15 pnp4nagios-0.6.24 rrdtool-1.4.9

nagios服务已经安装完成，下面先安装rrdtool，http://oss.oetiker.ch/rrdtool/ 

yum install  libjpeg-devel libpng-devel pango* libart_lgpl-devel pango-devel* cairo-devel* libxml2-devel libjpeg-devel libpng-devel php-gd gd-devel perl-GD libtoul-ltdl-devel rrdtool-perl perl-devel perl-ExtUtils-Embed perl-Time-HiRes

tar -xzf rrdtool-1.4.9.tar.gz 

cd rrdtool-1.4.9

./configure –prefix=/usr/local/rrdtool

make

make install

cd ..

安装pnp4nagios http://www.pnp4nagios.org/

tar -xzf pnp4nagios-0.6.24.tar.gz 
cd pnp4nagios-0.6.24
ls /usr/local/pnp
./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool
make all
make install 
make install-webconf  
make install-config  
make install-init
 
cd /usr/local/pnp4nagios/etc/ 
cp rra.cfg-sample rra.cfg

#PNP的五种模式 Synchronous Mode、Bulk Mode、Bulk Mode with NPCD、Bulk Mode with npcdmod、Gearman Mode http://docs.pnp4nagios.org/pnp-0.6/modes   

#下面是Bulk Mode with NPCD模式配置

cd /usr/local/nagios/etc/objects/

vim commands.cfg
# 'process-host-perfdata' command definition
#注释默认的process-host-perfdata和process-service-perfdata，添加以下
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.$TIMET$
 }

#启动npcd服务

/usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

vim /usr/local/nagios/etc/nagios.cfg
process_performance_data=1  
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata  
service_perfdata_file_template=DATATYPE::SERVICEPERFDATAtTIMET::$TIMET$tHOSTNAME::$HOSTNAME$tSERVICEDESC::$SERVICEDESC$tSERVICEPERFDATA::$SERVICEPERFDATA$tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$tHOSTSTATE::$HOSTSTATE$tHOSTSTATETYPE::$HOSTSTATETYPE$tSERVICESTATE::$SERVICESTATE$tSERVICESTATETYPE::$SERVICESTATETYPE$

vim localhost.cfg 
 define host{
        use                     linux-server,host-pnp #修改这里
        host_name               localhost
        alias                   localhost
        address                 127.0.0.1
        }
define service{
        use                             local-service,service-pnp #需要画图的都加上service-pnp      
        host_name                       localhost
        service_description             PING
        check_command                   check_ping!100.0,20%!500.0,60%
        }

vim templates.cfg
define host{
        name       host-pnp
        register   0
        action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
        process_perf_data 1
        }
define service{
        name       service-pnp
        register   0
        action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$ 
        process_perf_data 1
        }

配置完成，检查nagios配置后将nagios和apache重启

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

service nagios restart

service httpd restart

出现这个页面说明安装完成，那么将install.php删除后刷新即可看到出图的页面

mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php.bak

如下：

如果需要在nagios页面即可查看到动态曲线那么需要做如下改动：

到pnp4nagios-0.6.24解压目录下

cp pnp4nagios-0.6.24/contrib/ssi/status-header.ssi /usr/local/nagios/share/ssi/

vim /usr/local/nagios/etc/objects/templates.cfg 
define host{
        name       host-pnp
        register   0
        action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=_HOST_
        process_perf_data 1
        }
define service{
        name       service-pnp
        register   0
        action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDESC$  
        process_perf_data 1
        }

备注：

生成的rrd文件在此目录/usr/local/pnp4nagios/var/perfdata/localhost

如果因为网络不稳定导致出图问题，可以修改一下超时时间

vim /usr/local/pnp4nagios/etc/process_perfdata.cfg

TIMEOUT = 30  #默认是15秒
