Logstash中的JSON解析错误

Question

当尝试使用Logstash解析JSON数据时，解析似乎失败，并且我的JSON没有按预期发送给ES。任何建议都很好。尝试记录失败的Wordpress登录，但是对JSON的解析没有运气。

当前在FreeBSD 11上使用Logstash 6.4.2。

示例日志文件。文件除了此数据外别无其他。

{

"ip": "11.11.11.11"
}

Logstash配置

input {

    file {
        type => "json"
        codec => "json"
        sincedb_path => "/dev/null"
        path => "/var/log/lighttpd/badlogin.txt"
        start_position => "beginning"#
        tags => ["wpbadlogin"]
    }
}

#filter { }

output {

    stdout {
        codec => rubydebug
    }

    elasticsearch {

        hosts => ["10.0.5.30:9200"]
        template => "/usr/local/etc/logstash/templates/wpbadlogin.json"
        template_name => "wpbadlogin"
        template_overwrite => true
        index => "wpbadlogin"
    }
}
