Centos nagios监控windows主机并开启PNP模块

浏览数：40 / 时间：2015年06月11日

OS：centos 5.7final 32bit
Apache/2.4.2
PHP/5.3.13
Nagios Core 3.4.1
nagios-plugins-1.4.15
rrdtool-1.4.7
pnp4nagios-0.6.17

一、安装Apache
去Apache官网下载apr和apr-util
apr
./configure --prefix=/usr/local/apr
make
make install

apr-util
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config
make
make install

编译安装apache
./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
make
make install

二、安装PHP
./configure --prefix=/usr/local/php --with-gd --enable-sockets --with-zlib --with-jpeg-dir --with-freetype-dir --with-apxs2=/usr/local/apache2/bin/apxs
make
make install
vim /usr/local/apache2/conf/httpd.conf
找到DirectoryIndex 在后面添加index.php
并在最后增加
<IfModule mod_php5.c>
AddType application/x-httpd-php .php
AddType application/x-httpd-php .php .phtml .php3
AddType application/x-httpd-php-source .phps
</IfModule>

#/usr/local/apache2/bin/apachectl stop
#/usr/local/apache2/bin/apachectl start
至此apache已经支持php了

三、安装nagios
#useradd -m nagios
#groupadd nagios
#usermod -a -G nagios nagios
#usermod -a -G nagios apache

编译安装nagios
./configure --prefix=/usr/local/nagios --with-httpd-conf=/usr/local/apache2/conf
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf

/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.users admin 创建用户名为admin的验证文件
按要求输入密码。

#vim /usr/local/apache2/conf/httpd.conf
User deamon 改为 User nagios
Group deamon 改为 Group nagios
在最后加入Include conf/nagios.conf

# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
检查nagios.cfg是否有错误

#chkconfig --add nagios
#chkconfig nagios on

安装nagios-plugins
./configure --prefix=/usr/local/nagios
make
make install

乱码问题的解决方法：
修改httpd.conf文件，并找到以下文字，去掉“#”,重启apache
#LoadModule cgid_module modules/mod_cgid.so
#LoadModule actions_module modules/mod_actions.so

#vim /usr/local/nagios/etc/cgi.cfg
修改如下：
authorized_for_system_information=nagiosadmin,admin
authorized_for_configuration_information=nagiosadmin,admin
authorized_for_system_commands=nagiosadmin,admin
authorized_for_all_services=nagiosadmin,admin
authorized_for_all_hosts=nagiosadmin,admin
authorized_for_all_service_commands=nagiosadmin,admin
authorized_for_all_host_commands=nagiosadmin,admin

#vim /usr/local/nagios /etc/nagios.cfg
找到如下字段并去掉#号，监控windows主机
cfg_file=/usr/local/nagios/etc/objects/windows.cfg
在被监控主机上需装NSClinet软件并启用服务。

#vim /usr/local/nagios /etc/pages/contacts.cfg
将email地址改为自己的邮件地址，有报警直接发送给该地址

#vim /usr/local/nagios /etc/pages/windows.cfg
将ip address改为要监控的主机

#/usr/local/apache2/bin/apachectl stop
#/usr/local/apache2/bin/apachectl start
#service nagios start

四、安装pnp4nagios
首先安装rrdtool
./configure --prefix=/usr/local/rrdtool
make
make install
cp -r /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/* /usr/lib/perl5/5.8.8/i386-linux-thread-multi/

安装pnp4nagios
./configure --prefix=/usr/local/pnp4nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-httpd-conf=/usr/local/apache2/conf
make all
make install
make install-webconf
make install-config
make install-init

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

vim httpd.conf
加入如下文字
Include conf/pnp4nagios.conf
去掉LoadModule rewrite_module modules/mod_rewrite.so 的#

vim /usr/local/nagios/etc/nagios.cfg
process_performance_data=0改为1
下面的2行去掉#号
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata

vim /usr/local/nagios/etc/objects/commands.cfg
修改如下
define command {
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
}
define command {
command_name process-service-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl
}

vim /usr/local/nagios/etc/objects/templates.cfg
添加如下内容
define host {
name host-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
register 0
}
define service {
name srv-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}

vim /usr/local/nagios/etc/objects/windows.cfg
修改如下
define host{
use windows-server,host-pnp ; Inherit default values from a template
……
define service{
use generic-service,srv-pnp
……
check_command check_counter!-l "\\Network Interface(Broadcom BCM5708C NetXtreme II GigE [NDIS VBD Client])\\Bytes Sent/sec","%.f"
注意这里"%.f"必须加，不加不出图！
(%.f没有e格式，默认6位仅只小数点后面包含6位。%.2f带两位小数点)

mv /usr/local/pnp4nagios/share/install.php ii.php

至此架设nagios+rrdtool+pnp4nagios监控windows主机已经完成。
