nagios报警的问题
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
[*] # cat /etc/hosts
[*] # Do not remove the following line, or various programs
[*] # that require network functionality will fail.
[*] 127.0.0.1 localhost.localdomain localhost
[*] ::1 localhost6.localdomain6 localhost6
[*] 172.16.4.3nagios.comnagios ##一定要有本机的ip对应
2、hostname与/etc/sysconfig/network里的hostname一致，并与hosts里的一致 3、去nagios的web里，选择报警的服务（如果httpd），http://img1.运维网.com/attachment/201201/110506446.jpg
点击http旁边的这个摁钮，如果你看到notification状态为disabled http://img1.运维网.com/attachment/201201/110642409.jpg那么你可以选择右侧的http://img1.运维网.com/attachment/201201/110749730.jpg，然后选择commit 。http://img1.运维网.com/attachment/201201/110848197.jpg出现下面对话框http://img1.运维网.com/attachment/201201/110936204.jpg
下面查看一下nagios.log里的日志
[*] # tail -f nagios.log
[*] Auto-save of retention data completed successfully.
[*] Auto-save of retention data completed successfully.
[*] EXTERNAL COMMAND: ENABLE_SVC_NOTIFICATIONS;henan-cunchu;HTTP
[*] Caught SIGTERM, shutting down...
[*] Successfully shutdown... (PID=6823)
[*] Nagios 3.3.1 starting... (PID=25398)
[*] Local time is Fri Jan 13 11:13:54 CST 2012
[*] LOG VERSION: 2.0
[*] Finished daemonizing... (New PID=25399)
[*] SERVICE NOTIFICATION: nagiosadmin;henan-cunchu;HTTP;CRITICAL;notify-service-by-email;?.?杩..
如果内容有service notification这样的话，就代表nagios发送了邮件报警，下面是我接收到的报警邮件http://img1.运维网.com/attachment/201201/111609257.jpg
就代表你启动了这个http服务的报警了，这一步完成之后等待10s左右，刷新页面就能看看notification的状态变为enabled，而且能收到报警，其他的服务也类似这样操作。 本文出自 “吟—技术交流” 博客，请务必保留此出处http://dl528888.blog.运维网.com/2382721/763079
