nagios与zorka是如何协作的

*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]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:// /download] /download）下载Nagios core和Nagios plugins 这里（[ ttp://exchange. /directory/Addons/Monitoring-Agents/NRPE--2D-Nagios-Remote-Plugin-Executor/details] /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：[ /flguo/blog/419455#]?

1 2 3 4 5 6 7 8 9 10 11

apt-get install apache2 php5 libssl0.9.8 libssl-dev openssl libgd2-xpm-dev apache2-utils mailx openssl libssl-dev useradd -m nagios passwd nagios usermod -G nagios nagios groupadd nagcmd usermod -G nagcmd nagios usermod -G nagcmd www-data mkdir /usr/local/nagios chown -R nagios.nagios /usr/local/nagios ll -d /usr/local/nagios/

测试php安装成功： [ /flguo/blog/419455#]?

gedit var/www/phpindex.php <?php phpinfo(); ?>

解压nagios，编译安装：[ /flguo/blog/419455#]? nagios实施

1 2 3 4 5 6

./configure --with-command-group=nagcmd make all make install make install-init make install-config make install-commandmode

安装Nagios的WEB配置文件 [ /flguo/blog/419455#]?

/usr/bin/install -c -m 644 sample-config/httpd.conf /etc/apache2/conf-enabled/nagios.conf htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin service apache2 restart

安装Nagios 插件 [ /flguo/blog/419455#]?

1 2 3

cd ../nagios-plugins-2.0.3 ./configure --prefix=/usr/local/nagios make && make install

开启apache对cgi的支持： [ /flguo/blog/419455#]?

1	ln -s /etc/apache2/mods-available/cgi.load /etc/apache2/mods-enabled/cgi.load

设置启动Nagios的服务:[ /flguo/blog/419455#]?

1 2 3 4

<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 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
[ /flguo/blog/419455#]?

./configure -prefix=/usr/local/nagios -with-ssl-inc=/usr/include -with-ssl-lib=/usr/lib/x86_64-linux-gnu make all make install-plugin

测试连接：[ /flguo/blog/419455#]?

1	/usr/local/nagios/libexec/check_nrpe -n -H 202.117.54.248 -p 5669 -c 'nagios.cmd["MEM_POOL"]'

nagios配置完成后添加host，command, service,指定被监控的主机地址以及相关属性信息：
[ /flguo/blog/419455#]?

1 2 3 4 5 6 7 8 9 10 11 12

gedit /usr/local/nagios/etc/objects/hosts.cfg define host{ use linux-server host_name Nagios-Linux 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 [ /flguo/blog/419455#]?

1 2 3 4 5 6

gedit /usr/local/nagios/etc/objects/commands.cfg # '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： [ /flguo/blog/419455#]?

1 2 3 4 5 6 7

gedit /usr/local/nagios/etc/objects/services.cfg define service{ use local-service host_name Nagios-Linux service_description Check Memory 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
[ /flguo/blog/419455#]?

1 2 3 4

gedit /usr/local/nagios/etc/nagios.cfg # nrpe remote host monitoring cfg_file=/usr/local/nagios/etc/objects/hosts.cfg cfg_file=/usr/local/nagios/etc/objects/services.cfg

重新加载nagios：[ /flguo/blog/419455#]? nagios安装

1	service nagios reload

转至 nagios/ ，点击services
