Logstash基礎(chǔ)操作-Filter

Grok配置案例：

##啟動(dòng)文件配置：
#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{}
}
filter?{
grok?{
match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\
%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
???}
}
output?{
??stdout{
????codec?=>?"rubydebug"
??}
}
##輸出文件內(nèi)容
172.16.213.132?[07/Feb/2018:16:24:19?+0800]?"GET?/?HTTP/1.1"?403?5039
##顯示內(nèi)容
{
??????"@version"?=>?"1",
????"@timestamp"?=>?2019-11-10T06:02:42.865Z,
??????????"host"?=>?"localhost.localdomain",
???????"message"?=>?"172.16.213.132?[07/Feb/2018:16:24:19?+0800]?\"GET?/?HTTP/1.1\"?403?5039",
?????"timestamp"?=>?"07/Feb/2018:16:24:19?+0800",
?????????"bytes"?=>?"5039",
??????"response"?=>?"403",
??????"clientip"?=>?"172.16.213.132",
??????"referrer"?=>?"\"GET?/?HTTP/1.1\""
}

Grok 過濾重復(fù)字段

##?配置文件
#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{
?}
}
filter?{
??grok?{
??match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\?
??%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
??remove_field?=>?["message"]
???}
}
output?{
??stdout{
??codec?=>?"rubydebug"
??}
}

Grok搭配Date時(shí)間插件配置

#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{
??}
}
filter?{
grok?{
?match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\?
?%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
?remove_field?=>?["message"]
???}
date?{
??match?=>?["timestamp",?"dd/MMMM/yyyy:HH:mm:ss?Z"]
??}
}
output?{
??stdout{
??codec?=>?"rubydebug"
??}
}

Date 過濾重復(fù)得字段配置

#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{
??}
}
filter?{
?grok?{
???match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\?
???%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
???remove_field?=>?["message"]
???}
date?{
??match?=>?["timestamp",?"dd/MMMM/yyyy:HH:mm:ss?Z"]
??
??}
mutate?{
???remove_field?=>?[?"timestamp"?]??
??}
}
output?{
?stdout{
??codec?=>?"rubydebug"
??}
}

綜合練習(xí)配置參數(shù)

#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{
??}
}
filter?{
??grok?{
???match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\?
???%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
???remove_field?=>?["message"]
??}
?date?{
??match?=>?["timestamp",?"dd/MMMM/yyyy:HH:mm:ss?Z"]?
??}
?mutate{
????rename?=>?{"response"?=>?"response_new"}
????gsub?=>?["referrer",?"\"",?""]
????remove_field?=>?[?"timestamp"?]
????split?=>?["clientip",?"."]
??}
}
output?{
?stdout{
??codec?=>?"rubydebug"
??}
}

Geoip 地理位置插件操作方式

#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{
??}
}
filter?{
????grok?{
?????match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\?
?????%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
?????remove_field?=>?["message"]
???}
???date?{
????match?=>?["timestamp",?"dd/MMMM/yyyy:HH:mm:ss?Z"]?
??}
???mutate{
??????remove_field?=>?[?"timestamp"?]
??}
??geoip?{
????source?=>?"clientip"
????database?=>?"/usr/local/include/GeoLite2-ASN_20191105/GeoLite2-ASN.mmdb"
???}
}
output?{
??stdout{
????codec?=>?"rubydebug"
??}?
}

Geoip輸出指定屬性值

#?Sample?Logstash?configuration?for?creating?a?simple
#?Beats?->?Logstash?->?Elasticsearch?pipeline.
input?{
??stdin{
??}
}
filter?{
????grok?{
?????match?=>?["message","%{IP:clientip}\?\[%{HTTPDATE:timestamp}\]\?
?????%{QS:referrer}\?%{NUMBER:response}\?%{NUMBER:bytes}"]
?????remove_field?=>?["message"]
???}
???date?{
????match?=>?["timestamp",?"dd/MMMM/yyyy:HH:mm:ss?Z"]
??}
???mutate{
??????remove_field?=>?[?"timestamp"?]
??}
geoip?{
source?=>?"clientip"
#database?=>?"/usr/local/include/GeoLite2-Country_20191015/GeoLite2-Country.mmdb"
database?=>?"/usr/local/include/GeoLite2-City_20191105/GeoLite2-City.mmdb"
fields?=>?["city_name",?"region_name",?"country_name",?"ip",?"latitude",?"longitude",?"timezone"]
???}
}
output?{
??stdout{
????codec?=>?"rubydebug"
??}
}
模擬數(shù)據(jù)：
36.7.152.182?[07/Feb/2018:16:24:19?+0800]?"GET?/?HTTP/1.1"?403?5039

#?Sample?Logstash?configuration?for?creating?a?simple
