98.4.2. filter

98.4.2.1. 日期格式化

系统默认是 ISO8601 如果需要转换为 yyyy-MM-dd-HH:mm:ss 参考:

				

filter {
  date {
    match => [ "ctime", "yyyy-MM-dd HH:mm:ss" ]
    locale => "cn"
  }
 date {
    match => [ "mtime", "yyyy-MM-dd HH:mm:ss" ]
    locale => "cn"
  } 
}				
				
				
98.4.2.2. patterns

创建匹配文件 /usr/share/logstash/patterns

				
mkdir /usr/share/logstash/patterns
vim /usr/share/logstash/patterns

NGUSER %{NGUSERNAME}
NGINXACCESS %{IPORHOST:clientip} %{NGUSER:ident} %{NGUSER:auth} \[%{HTTPDATE:timestamp}\] "%{WORD:verb} %{URIPATHPARAM:request} HTTP/%{NUMBER:httpversion}" %{NUMBER:response} (?:%{NUMBER:bytes}|-) (?:"(?:%{URI:referrer}|-)"|%{QS:referrer}) %{QS:agent}

    }
  }
}

  }
  syslog {
    type => "syslog"
    port => "5544"
  }
}
 
filter {
  grok {
    type => "syslog"
    match => [ "message", "%{SYSLOGBASE2}" ]
    add_tag => [ "syslog", "grokked" ]
  }
}
 
output {

    }
}
 
filter {
	csv {
		columns => ["Code","Source"]
		separator => ","
	}
	kv {
		source => "uri"
		field_split => "&?"
		value_split => "="
	}
 
}
 
# output logs to console and to elasticsearch
output {
    stdout {}
    elasticsearch {
        hosts => ["172.16.1.1:9200"]
    }
}

input {
    stdin {}
}
filter {
    ruby {
        init => "
            begin
                @@csv_file    = 'output.csv'
                @@csv_headers = ['A','B','C']
                if File.zero?(@@csv_file) || !File.exist?(@@csv_file)
                    CSV.open(@@csv_file, 'w') do |csv|
                        csv << @@csv_headers
                    end
                end
            end
        "
        code => "
            begin
                event['@metadata']['csv_file']    = @@csv_file
                event['@metadata']['csv_headers'] = @@csv_headers
            end
        "
    }
    csv {
        columns => ["a", "b", "c"]
    }
}
output {
    csv {
        fields => ["a", "b", "c"]
        path   => "%{[@metadata][csv_file]}"
    }
    stdout {
        codec => rubydebug {
            metadata => true
        }
    }
}				
				
				

测试

				
echo "1,2,3\n4,5,6\n7,8,9" | ./bin/logstash -f csv-headers.conf				
				
				

输出结果

				
A,B,C
1,2,3
4,5,6
7,8,9
				
				
98.4.2.6. 执行 ruby 代码

日期格式化, 将ISO 8601日期格式转换为 %Y-%m-%d %H:%M:%S

保存下面内容到配置文件data.conf

				
input {
	stdin{}
}
filter {

	ruby {
		init => "require 'time'"
        code => "event.set('ctime', event.get('ctime').time.localtime.strftime('%Y-%m-%d %H:%M:%S'))"
    }

	ruby {
		init => "require 'time'"
        code => "event.set('mtime', event.get('mtime').time.localtime.strftime('%Y-%m-%d %H:%M:%S'))"
    }
}
output {

	stdout {
		codec => rubydebug
	}

}
				
				

/usr/share/logstash/bin/logstash -f date.conf

配置实现每日切割一个 index

					
index => "logstash-%{+YYYY.MM.dd}"

"_index" : "logstash-2017.03.22"	
					
					

index 自定义 logstash-%{type}-%{+YYYY.MM.dd}

					
input {

    redis {
        data_type => "list"
        key => "logstash:redis"
        host => "127.0.0.1"
