由于无法访问SMTP服务器、未生成事件通知

适用场景

问题描述

• 按照以下知识库文章为电子邮件通知配置事件筛选器： 如何为电子邮件目标配置事件筛选器和事件通知

::> event notification show
ID   Filter Name                     Destinations
---- ------------------------------  -----------------
1    default-trap-events             snmp-traphost
2    Events_filter                   Email_Notification
3    Events_filter                Syslog
3 entries were displayed.

• 如果尝试为电子邮件通知生成测试事件、则不会触发任何事件：

::> set diag
::*> event generate -node Node-01 -message-name monitor.volume.nearlyFull -values TEST,TEST,TEST,TEST,TEST,TEST

::*> event notification history show -destination Email_Notification
There are no entries matching your query.

• 但是、系统日志服务器上会针对 同一筛选器触发事件：

::*> event notification history show -destination Syslog
Time         Node        Severity    Event
------------------- ---------------- ------------- ---------------------------
11/20/2023 06:32:52 Node-01         ERROR      monitor.volume.nearlyFull: TEST TESTTESTTEST is nearly full (using or reserving TEST% of space and TEST% of inodes).

• 事件配置中会提及SMTP主机名：

::*> event config show
               Mail From:  admin@localhost
              Mail Server:  smtp.server.com
               Proxy URL:  -
               Proxy User:  -
  Publish/Subscribe Messaging Enabled:  true

• 尝试对SMTP服务器执行ping操作失败、并显示以下错误：

::*> network ping -node Node-01 -destination smtp.server.com
Unknown host smtp.server.com
