nagios监控三部曲之——为什么nagios不能发送报警邮件(2)

最近我写了关于naigos监控的安装与配置的技术文档，公司运维按照我的文档部署naigos，发现不能发送报警邮件，经过我的检查，发现问题如下：

1、hosts里的配置

1. [root@nagios ~]# cat /etc/hosts  
2. # Do not remove the following line, or various programs  
3. # that require network functionality will fail.  
4. 127.0.0.1   localhost.localdomain localhost  
5. ::1     localhost6.localdomain6 localhost6  
6. 172.16.4.3  nagios.com  nagios ##一定要有本机的ip对应  

3、去nagios的web里，选择报警的服务（如果httpd），

点击http旁边的这个摁钮，如果你看到notification状态为disabled       那么你可以选择右侧的，然后选择commit 。出现下面对话框

1. [root@nagios var]# tail -f nagios.log
2. [1326419317] Auto-save of retention data completed successfully.
3. [1326422917] Auto-save of retention data completed successfully.
