版本说明：系统CentOS6.5 64位 nagios-4.0.5nagios-plugins-2.0 nrpe-2.15pnp4nagios-0.6.24rrdtool-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-gdgd-devel perl-GD libtoul-ltdl-devel rrdtool-perl perl-devel perl-ExtUtils-Embedperl-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pnp4nagioshttp://www.pnp4nagios.org/

#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/

#启动npcd服务

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

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.cfgdefinehost{namehost-pnpregister0action_url/pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_'class='tips'rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=_HOST_process_perf_data1}defineservice{nameservice-pnpregister0action_url/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$'class='tips'rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDESC$process_perf_data1}

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
