email - Nagios 不发送电子邮件

Question

我想设置 nagios 来发送电子邮件通知。
我可以通过单击 nagios Web 界面中的“发送自定义服务通知”手动发送电子邮件通知。正在创建通知，并且正在成功发送和发送电子邮件。
但是 nagios 不会自动发送通知。我已经测试过它关闭了机器上的 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

如何强制 nagios 发送通知电子邮件？

Answer 1

我有一个类似的问题。结果是两个问题的结合:

1) 我等待警报的时间不够长。将服务的 normal_check_interval 和 retry_check_interval*max_check_attempts 相加，您会发现必须等待 9 分钟才能收到通知。如果您必须更快地了解服务的故障，请减少 normal_check_interval 和 max_check_attempts。请注意，使用默认的 Nagios 配置，它可能需要 15 分钟才能通知您。

2) linux-server 的默认配置是在工作时间通知你，但有问题的服务器是 UTC。确保任何地方的 notification_period 变量都是 24x7。

祝你好运。
