Nagios 中文安装（二）
到此在cacti中添加npc插件来调用nagios# cd /usr/local/apache/htdocs/cacti/plugins
# tar -zxvf /install/npc-2.0.4.tar.gz
# vim ../include/config.php
$plugins[] = "npc";
测试：

(15)PNP
# tar -zxvf pnp-0.4.13.tar.gz -C /usr/src/
# cd /usr/src/pnp-0.4.13/
# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata
# make all
# make install
# make install-config
# make install-init
配置pnp
# cd /usr/local/nagios/etc/pnp/
# cp process_perfdata.cfg-sample process_perfdata.cfg
# cp npcd.cfg-sample npcd.cfg
# cp rra.cfg-sample rra.cfg
# chown -R nagios:nagios /usr/local/nagios/etc/pnp/
# vim /usr/local/nagios/etc/pnp/process_perfdata.cfg
LOG_FILE = /usr/local/nagios/var/perfdata.log
# Loglevel 0=silent 1=normal 2=debug
LOG_LEVEL = 2
修改nagios配置文件
1、
# vim /usr/local/nagios/etc/objects/templates.cfg
define host{
name hosts-pnp
register 0
action_url /nagios/pnp/index.php?host=$HOSTNAME$
process_perf_data
}
##############################################################
define service {

}
2、
# vim /usr/local/nagios/etc/nagios.cfg
833 process_performance_data=1
845 host_perfdata_command=process-host-perfdata
846 service_perfdata_command=process-service-perfdata
3、
# vim /usr/local/nagios/etc/objects/commands.cfg
# 'process-host-perfdata' command definition
define command{

(16)配置Nagios客户端（远程主机）
# yum -y install *gcc*
# useradd -s /sbin/nologin nagios
# tar -zxvf nagios-plugins-1.4.14.tar.gz -C /usr/src/
# cd /usr/src/nagios-plugins-1.4.14/
# ./configure
# make
# make install
# chown nagios:nagios /usr/local/nagios/
# chown -R nagios:nagios /usr/local/nagios/libexec/
安装NRPE
# tar -zxvf nrpe-2.12.tar.gz -C /usr/src/
# cd /usr/src/nrpe-2.12/

在服务端安装NRPE和配置nagios
# tar -zxvf nrpe-2.12.tar.gz -C /usr/src/
# cd /usr/src/nrpe-2.12/
# ./configure
# make all
# make install-plugin
测试插件于客户端是否通信
# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.115
NRPE v2.12
定义一个check_nrpe命令
# vim /usr/local/nagios/etc/objects/commands.cfg
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
添加远程主机监控在这我们监控远程主机服务：用户数、CPU利用率
# vim /usr/local/nagios/etc/objects/services.cfg
define service{
use local-service,services-pnp
host_name 125-server
service_description users
check_command check_nrpe!check_users
}
define service{
use local-service,services-pnp
host_name 125-server
service_description load
check_command check_nrpe!check_load
}
define service{
use local-service,services-pnp
host_name 125-server
service_description swap
check_command check_nrpe!check_swap
}
define service{
use local-service,services-pnp
host_name 125-server
service_description Total Proocesses
check_command check_nrpe!check_total_procs
}
define service{
use local-service,services-pnp
host_name 125-server
service_description Zombie Proocesses
check_command check_nrpe!check_zombie_procs
}
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
# service nagios stop
# service nagios start
