Logstash电子邮件警报

Question

我配置了logstash以发送电子邮件警报，以防日志消息中包含某些单词组合。 我收到警报，但没有收到警报中的消息字段值，而是收到单词“ @message”。 我怎么解决这个问题？

这是我的logstash配置文件：

root@srv-syslog:~# cat /etc/logstash/conf.d/central.conf
input {
    syslog {
        type => "syslog"
        port => 5144
    }
    tcp {
        type => "cisco_asa"
        port => 5145
    }
    tcp {
        type => "cisco_ios"
        port => 5146
    }
}
output {
    elasticsearch {
        bind_host => "127.0.0.1"
        port => "9200"
        protocol => http
    }
    if "executed the" in [message]  {
        email {
            from => "logstash_alert@company.local"
            subject => "logstash alert"
            to => "myemail@company.local"
            via => "smtp"
            body => "Here is the event line that occured: %{@message}"
        }
    }
}

Answer 1

在这种情况下，字段名称是message ，而不是@message 。

观看演示：

input {
    generator {
        count => 1
        lines => ["Example line."]
    }
}

filter {
    mutate {
        add_field => {
            "m1" => "%{message}"
            "m2" => "%{@message}"
        }
    }
}

output {
    stdout {
        codec => rubydebug{}
    }
}

对于您的情况，您只需要修复以下一行：

body => "Here is the event line that occured: %{message}"

Answer 2

删除@符号。 该字段是消息，而不是@message。
