##启动文件配置: # 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" } } ##输出文件内容 172.16.213.132 [07/Feb/2018:16:24:19 +0800] "GET / HTTP/1.1" 403 5039 ##显示内容 { "@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 过滤重复字段
## 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时间插件配置
# 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 过滤重复得字段配置
# 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" } }
综合练习配置参数
# 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输出指定属性值
# 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" } } 模拟数据: 36.7.152.182 [07/Feb/2018:16:24:19 +0800] "GET / HTTP/1.1" 403 5039
