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::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_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
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
