nagios与zorka是如何协作的
来自：网络
*简介：Nagios是一款开源的免费网络监视工具，Zorka增加了与nagios连接的NRPE协议和基本的bsh配置文件。
我在之前的博客（fliguo/article/details/45367043）详细介绍了如何配置zorka对tomcat的监控 nagios培训
在此基础上我们配置nagios，使之与zorka协同运行。
官网（[ ttp://www. /download]http://www. /download）下载Nagios core和Nagios plugins
这里（[ ttp://exchange. /directory/Addons/Monitoring-Agents/NRPE--2D-Nagios-Remote-Plugin-Executor/details]http://exchange. /direc ... in-Executor/details）下载NRPE插件
被监控端zorka配置，启动tomcat：添加至nagios配置项到zorka.properties:

# nagios setting
nagios = yes
nagios.listen.addr = 202.117.10.234
nagios.listen.port = 5669
nagios.server.addr = 192.168.60.129
监控主机端Ubuntu 15.04下配置nagios：环境配置：?

开启apache对cgi的支持：
?

ln -s /etc/apache2/mods-available/cgi.load /etc/apache2/mods-enabled/cgi.load
设置启动Nagios的服务:?

<pre name="code" class="plain">ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
/etc/init.d/nagios start
(这里也可以用service nagios start或者 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg）
访问 http://localhost/nagios/就可以得到结果 监控软件 -u nagiosadmin
-p yourpassword
这是可以访问nagios，查看预定义的对本机监控的结果了。

编译安装活动监控代理NRPE：安装NRPE后nagios定时查询将有NRPE代理

alias Nagios-Linux
address 192.168.60.134 #被监控的主机地址，这个地址可以是ip，也可以是域名。
}
define hostgroup{
hostgroup_name zorka-servers
alias zorka servers
members Nagios-Linux
}
指定NRPE发送的命令格式： nagios配置 ?

# 'check_zorka' command definition
define command{
command_name check_zorka
command_line $USER1$/check_nrpe -n -H $HOSTADDRESS$ -p 5669 -c 'nagios.cmd["$ARG1$"]'
}
添加监控的service，这里以监控内存为例：

gedit /usr/local/nagios/etc/objects/services.cfg
define service{

check_command check_zorka!MEM_POOL
}
将配置文件包含在nagios配置文件中，重新加载nagios配置文件： 开源监控软件

重新加载nagios：? nagios安装
