Logstash基础操作-Filter

Grok配置案例：

##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
