我想设置nagios来发送电子邮件通知。我可以手动发送电子邮件通知，单击nagios Web界面中的“发送自定义服务通知”。正在创建通知，并且正在成功发送和传递电子邮件。但是nagios不会自动发送通知。我已经测试了它关闭了机器上的PING服务（echo 1> / proc / sys / net / ipv4 / icmp_echo_ignore_all）。 Nagios将PING服务设置为CRITICAL状态，但不发送通知电子邮件。
这些是我的配置文件：
templates.cfg的一部分

service_notification_period 24x7 ; service notifications can be sent anytime
host_notification_period 24x7 ; host notifications can be sent anytime

如何强制nagios发送通知电子邮件？
我有一个类似的问题。结果证明是两个问题的组合：
1）我没有等待足够长的警报。为服务添加normal_check_interval和retry_check_interval * max_check_attempts，您将看到在收到通知之前必须等待9分钟。如果必须更快地了解服务故障，请减少normal_check_interval和max_check_attempts。请注意，使用默认的Nagios配置，它可能会在通知您之前多达15分钟。
2）linux-server的默认配置是在工作时间通知您，但有问题的服务器是UTC。确保notification_period变量在任何地方都是24x7。
祝好运。
检查主nagios.cfg文件并确保notifications_enabled = 1。同时验证您的基本联系人模板是否也包含notifications_enabled = 1。
还请考虑flap_detection_enabled设置。如果启用此设置并确定存在振荡，Nagios将不会通知。振荡是指服务经常在OK，soft和normal状态之间切换。在测试期间，当我们测试以确保一切正常时，服务通常会“翻动”。在测试期间禁用主机和服务配置文件中的flap_detection_enabled设置。
