29 Pipeline Worker(s) Input Queue Filter Output

30 # logstash.conf input { file { path => "/tmp/log.txt" } } filter {} output { stdout { codec=>rubydebug } } $ bin/logstash -f logstash.conf

31 T03:44:01.103Z client logged on filter { grok { match => { "message" => "%{NOTSPACE:timestamp} %{NOTSPACE:client_ip} %{GREEDYDATA:action}" } } }

32 filter { grok { match => { "message" => \ "%{TIMESTAMP_ISO8601:timestamp} %{IP:client_ip} %{GREEDYDATA:action}" } } date { match => [ "timestamp", "ISO8601" ] } }

33 filter { translate { field => "client_ip" destination => "user" dictionary => [ " ", "User A", " ", "User B" ] fallback => "Unknown user" } }

34 input { stdin { codec => json } } filter {} input { stdin {} } filter { json { source => "message" } }

35 Tips GROK CSV CSV filter GROK - Ruby on Rails, Java stack trace Multiline codec Netflow Codec Netflow "module"

36 $ cat conf/input.conf input { stdin {} } $ cat conf/filter.conf filter {} $ cat conf/output.conf output { stdout { codec=>rubydebug } } $ bin/logstash -f conf
