NAGIOS插件pnp4nagios安装
注：nagios版本nagios4.0.8

1.下载安装 pnp4nagios-0.6.25.tar.gz

wget http://sourceforge.net/projects/pnp4nagios/files/PNP-0.6/pnp4nagios-0.6.25.tar.gz

yum -y install rrdtool perl-Time-HiRes perl-File-Tail rrdtool rrdtool-perl php-gd

tar zxvf? pnp4nagios-0.6.25.tar.gz

cd pnp4nagios-0.6.25

#perl -MRRDs -le ‘print q(ok!)‘
如果返回值是ok!，则可以进行pnp4nagios配置和安装
#./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/bin/rrdtool?--with-perl_lib_path=/usr/lib64/perl5/vendor_perl/auto/RRDs
#make all
#make install
#make install-webconf
#make install-config
#make install-init

2.创建配置文件

cd /usr/local/pnp4nagios/etc

mv misccommands.cfg-sample? misccommands.cfg

mv nagios.cfg-sample? nagios.cfg

mv npcd.cfg-sample npcd.cfg

mv process_perfdata.cfg-sample? process_perfdata.cfg

#?mv rra.cfg-sample rra.cfg

#? cd pages

mv web_traffic.cfg-sample web_traffic.cfg

cd ../check_commands

mv check_all_local_disks.cfg-sample? check_all_local_disks.cfg

mv check_nrpe.cfg-sample? check_nrpe.cfg

mv check_nwstat.cfg-sample? check_nwstat.cfg

1. 重启服务

   /etc/init.d/npcd restart

   echo “/etc/init.d/npcd start”>>/etc/rc.local
   4.修改 nagios 的配置文件.打开performance_data

   cd /usr/local/nagios/etc

   vim nagios.cfg

   #打开注释项：
   process_performance_data=1
   host_perfdata_command=process-host-perfdata
   service_perfdata_command=process-service-perfdata
   #######################添加如下内容####################################
   service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
   service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICEC::HECKCOMMAND::$SERVICECHECKCOMMAND$\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 performancedata 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
   ###########################################################
   5.修改 commands.cfg

   cd /usr/local/nagios/etc/objects

   vim commands.cfg

   ##添加
   #################################################################
   define command{
   command_name process-service-perfdata
   command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
   }

define command{
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
}

1. 添加小太阳模版，镶嵌在nagios页面上。

   vim templates.cfg

   在最后添加

   define host {
   name host-pnp
   action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=HOST
   register 0
   }
   define service {
   name srv-pnp
   action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
   register 0
   }
   7，修改 hosts.cfg 和services.cfg

   cd /usr/local/nagios/etc/objects

   #修改hosts.cfg

   vim hosts.cfg

   define host{
   ????????use???????????????????? linux-server,host-pnp??
   ????????host_name????????? wwwserver
   ????????alias???????????????????? wwwserver
   ????????address????????????????? 10.10.10.111
   ????????}

修改 services.cfg

define service{
????????use???????????????????????? ?local-service,srv-pnp??????
????????host_name?????????????????? ?wwwserver
????????service_description???????? PING
????????check_command???????????? check_ping!100.0,20%!500.0,60%
}
其他的主机和服务以此类推
检查配置文件正确与否
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

返回值如上图片，则重启nagios
8.重启?nagios?服务
#/etc/init.d/nagios restart
效果图：

这时点击小太阳会出现如下提示：The requested URL /pnp4nagios/graph was not found on this server.
解决方法如下：
原因，当你在pnp4nagios安装的时候执行了make install-webconf，注意它生成了一个apache的配置文件。
你把这个文件：/etc/httpd/conf.d/pnp4nagios.conf?中的所有内容全部添加到apache的httpd.conf文件最后，再重新启动nagios和apache就应该可以啦。

[[email protected] etc]# find / -name pnp4nagios.conf
/etc/httpd/conf.d/pnp4nagios.conf
[[email protected] etc]# vim /etc/httpd/conf.d/pnp4nagios.conf
[[email protected] etc]# cat /etc/httpd/conf.d/pnp4nagios.conf>>/usr/local/apache/conf/httpd.conf
#service httpd restart
#service Nagios restart
这时再点击小太阳，会出现pnp4nagios的测试页，结果如下：

告诉要删掉或重命名/usr/local/pnp4nagios/share/install.php
故障2：
安装测试：
http://monitor.dreamlive.tv//pnp4nagios/index.php

#cd /usr/local/pnp4nagios/share
#mv install.php install.php.bak
在此测试：显示如下：

没有图像出现，主要原因就是：导致
解决方法：

改为：

重启httpd
结果就正常了

报如下错误

Yum -y install pango pango-devel
然后重启系统
