*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[/url])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[/url])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[/url])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:

/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。
