Ruby Fluentd自定义解析器插件引发未初始化的常量Fluent错误

我正在尝试实现一个自定义解析器插件。正如中所建议的，我创建了名为

parser\u unordered\u multiline.rb的以下文件，并将其放置在
/etc/td-agent/plugin/
位置

module Fluent
    class TextParser
        class UnorderedMultilineParser < Parser

            Plugin.register_parser('unordered_multiline', self)

            ## Define configuration params
            config_param :delimiter, :string, :default => " "
            config_param :time_format, :string, :default => nil

            ## configures our parser plugin
            def configure(conf)
                super

                if @delimiter.length != 1
                    raise ConfigError, "delimiter must be a single character. #{@delimiter} is not."
                end

                @time_parser = TimeParser.new(@time_format)
            end


            def parse(text)
                time, key_values = text.split(" ", 2)
                time = @time_parser.parse(time)
                record = {}
                key_values.split(@delimiter).each { |kv|
                    k, v = kv.split("=", 2)
                    record[k] = v
                }

                yield time, record

            end
        end
    end
end

下面是完整的堆栈跟踪

这就是我的配置文件的样子

<source>
    type tail
    path /var/log/mail/mail*
    pos_file /var/log/td-agent/tmp/access.log
    exclude_path ["/var/log/mail/*.gz", "/var/log/mail/*.zip"]
    read_from_head true
    time_format %M %d %H:%M:%S
    port 5140
    format unordered_multiline
    tag  mail
</source>


<match mail>
    type copy
    <store>
       type elasticsearch
       logstash_format true
       flush_interval 30s
    </store>
</match>


型尾
路径/var/log/mail/mail*
pos_文件/var/log/td-agent/tmp/access.log
排除路径[“/var/log/mail/*.gz”，“/var/log/mail/*.zip”]
从你的头上读出来是真的
时间\u格式%M%d%H:%M:%S
5140端口
设置无序多行的格式
标签邮件
打印副本
类型弹性搜索
logstash_格式为true
冲洗间隔30秒

我是ruby和fluentd的新手，有人能告诉我这个错误是怎么回事吗

更新
根据调查，甚至这条路似乎都是正确的

<source>
    type tail
    path /var/log/mail/mail*
    pos_file /var/log/td-agent/tmp/access.log
    exclude_path ["/var/log/mail/*.gz", "/var/log/mail/*.zip"]
    read_from_head true
    time_format %M %d %H:%M:%S
    port 5140
    format unordered_multiline
    tag  mail
</source>


<match mail>
    type copy
    <store>
       type elasticsearch
       logstash_format true
       flush_interval 30s
    </store>
</match>
