nagios安装PNP图形化工具

首先安装必要软件：

安装扩展源：

访问https://fedoraproject.org/wiki/EPEL/zh-cn，选择相应的epel-release'包

安装：

wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

rpm -Uvh epel-release-5-4.noarch.rpm

yum -y install php-gd rrdtool-perl rrdtool

或是编译安装：(不建议，依赖关系太复杂)

1、从http://oss.oetiker.ch/rrdtool/pub/?M=D 下载最新的的RRDtool：

wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.6.tar.gz

tar xzf rrdtool-1.4.6.tar.gz

cd rrdtool-1.4.6

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

make && make install

2、从http://sourceforge.net/projects/pnp4nagios/files/PNP-0.4/ 下载最新的pnp

wget http://nchc.dl.sourceforge.net/sourceforge/pnp4nagios/pnp-0.4.14.tar.gz

tar -xzf pnp-0.4.14.tar.gz

cd pnp-0.4.14

./configure --with-nagios-user=nagios --with-nagios-group-nagios --with-rrdtool=/usr/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata/

make all

make install

make install-config

make install-init

修改配置文件：

cd /usr/local/nagios/etc/pnp/

rename .cfg-sample .cfg *.cfg-sample

vi process_perfdata.cfg

#可不改

# Loglevel 0=silent 1=normal 2=debug

#

#LOG_LEVEL = 0

LOG_LEVEL = 2 #日志级别改成debug模式

修改templates.cfg

vi /usr/local/nagios/etc/objects/templates.cfg

#add pnp host service

define host {

name hosts-pnp

register 0

action_url /nagios/pnp/index.php?host=$HOSTNAME$

process_perf_data 1

}

define service {

name services-pnp

register 0

action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$

process_perf_data 1

}

修改：

vi /usr/local/nagios/etc/nagios.cfg

#Default Mode:

process_performance_data=1

host_perfdata_command=process-host-perfdata

service_perfdata_command=process-service-perfdata

#Bulk Mode with NPCD:

process_performance_data=1

service_perfdata_file=/usr/local/nagios/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/nagios/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

修改：

vi /usr/local/nagios/etc/objects/commands.cfg

两种模式任选一种即可

#Default Mode:

# 'process-host-perfdata' command definition

define command{

command_name process-host-perfdata

command_line /usr/local/nagios/libexec/process_perfdata.pl

}

# 'process-service-perfdata' command definition

define command{

command_name process-service-perfdata

command_line /usr/local/nagios/libexec/process_perfdata.pl

}

#Bulk Mode with NPCD:

define command{

command_name process-service-perfdata-file

command_line /bin/mv /usr/local/nagios/var/service-perfdata /usr/local/nagios/var/spool/perfdata/service-perfdata.$TIMET$

}

define command{

command_name process-host-perfdata-file

command_line /bin/mv /usr/local/nagios/var/host-perfdata /usr/local/nagios/var/spool/perfdata/host-perfdata.$TIMET$

}

修改相应的主机文件例如：

vi /usr/local/nagios/etc/hosts/192.168.56.103.cfg

define host{

use linux-server,hosts-pnp ; Name of host template to use

; This host definition will inherit all variables that are defined

; in (or inherited by) the linux-server host template definition.

host_name 192.168.56.103

alias Debian 6.0 Server

address 192.168.56.103

contact_groups admins

}

define service{

use generic-service,services-pnp

host_name 192.168.56.103

check_command check_http

register 1

}

启动npcd服务：

/usr/local/nagios/bin/npcd -d -f /usr/local/nagios/etc/pnp/npcd.cfg

显示PHP GD Support not found.

安装 yum -y install php-gd

重启apache服务：

/etc/init.d/httpd restart

启动顺序：

nagios->npcd

加入自启动：

vi /etc/rc.local

#add nagios pnp

/usr/local/nagios/bin/npcd -d -f /usr/local/nagios/etc/pnp/npcd.cfg
