发送邮件(Email)

配置示例

output {
    email {
        to => "[email protected],[email protected]"
        cc => "[email protected]"
        via => "smtp"
        subject => "Warning: %{title}"
        options => {
            smtpIporHost       => "localhost",
            port               => 25,
            domain             => 'localhost.localdomain',
            userName           => nil,
            password           => nil,
            authenticationType => nil, # (plain, login and cram_md5)
            starttls           => true
        }
        htmlbody => ""
        body => ""
        attachments => ["/path/to/filename"]
    }
}

注意：以上示例适用于 Logstash 1.5 ，options => 的参数配置在 Logstash 2.0 之后的版本已被移除，（126 邮箱发送到 qq 邮箱）示例如下：

output {
    email {
        port           =>    "25"
        address        =>    "smtp.126.com"
        username       =>    "[email protected]"
        password       =>    ""
        authentication =>    "plain"
        use_tls        =>    true
        from           =>    "[email protected]"
        subject        =>    "Warning: %{title}"
        to             =>    "[email protected]"
        via            =>    "smtp"
        body           =>    "%{message}"
    }
}

解释

outputs/email 插件支持 SMTP 协议和 sendmail 两种方式，通过 via 参数设置。SMTP 方式有较多的 options 参数可配置。sendmail 只能利用本机上的 sendmail 服务来完成 —— 文档上描述了 Mail 库支持的 sendmail 配置参数，但实际代码中没有相关处理，不要被迷惑了。。。
