如何配置 logstash 电子邮件输出插件以发送电子邮件警报。

Ensure postfix or sendmail is configured on the logstash server, refer to another post here which config postfix with gmail smtp to send email

Create a new logstash conf file in /etc/logstash/conf.d and add below content

input {
   syslog {
        type => syslog
        port => 5514
      }
    }

output {
   email {
        to => "username@example.com"
        subject => "Test from logstash email output"
        body => "The message from logstash input: %{message}"
      }
    }

Next restart logstash

$ service logstash restart

Finally test with telnet in another terminal on the same vm

$ telnet localhost 5514
$ => then after connected, enter some message and press enter

In a few seconds the actual "username@example.com" should receive an email sent by logstash with the subject and body matching what's configured above.
