about开源监控nagios.

nagios作为开源监控工具，以其快速定位故障的能力而闻名。同类软件如cacti，zabbix，gangla等等。

这里只是做个笔记。一些小技巧吧。

一.因为监控软件我们一般放在内网的主体网络中。或者通过添加路由的方式来监控整个网络。

作为内网去监控整个平台，建议取消输入用户名以及密码的功能。

方法：在apache主配置文件中添加如下带颜色的代码即可。

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
#  SSLRequireSSL
   Options ExecCGI
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
   AuthName "Nagios Access"
   AuthType Basic
   satisfy  any
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
#   AuthUserFile /usr/local/nagios/etc/htpasswd.admin
   Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
#  SSLRequireSSL
   Options None
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
