Integration between Filebeat and logstash

  1. 1. Integration between Logstash and Filebeat charsyam@naver.com
  2. 2. Integration between Logstash and Filebeat Filebeat Logstash Filebeat sends logs to logstash.
  3. 3. Common Config : Filebeat filebeat.prospectors: - type: log enabled: true paths: - /data/logs/reallog/2018-12-27.log output.logstash: hosts: ["target.aggserver.com:5044"]
  4. 4. Common Config : Logstash input { beats { port => 5044 } } output { file { path => "/data/logstash/2018-12-27.log" codec => line { format => "%{message}" } } }
  5. 5. Case #1 : Simple, one file to one file Just use common config
  6. 6. Case #1 : Simple, one file to one file But we don’t need this case
  7. 7. Case #2 : Simple, multiple files to one file filebeat.prospectors: - type: log enabled: true paths: - /data/logs/reallog/*.log Just use *.
  8. 8. Case #3 : Advance, multiple files to multiple files : Just move content by each file filter { grok { match => {"source" => "data/logs/%{DATA:logdate}.log"} } } output { file { path => "/data/logstash/%{logdate}.log" codec => line { format => "%{message}" } } } Filebeat sends original filename with source field
  9. 9. Case #4 : Advance, multiple files to multiple files : with log timestamp filter { grok { patterns_dir => ["/usr/local/logstash-5.4.1/patterns"] match => { "message" => "^%{TIMESTAMP_ISO8601:timestamp}" } } date { match => ["timestamp", "yyyy-MM-dd"] } } output { file { path => "/data/logstash/%{+YYYY-MM-dd}.log" codec => line { format => "%{message}" } } } Filtering timestamp and using it as filename.
  10. 10. Case #4 : Advance, multiple files to multiple files : with log timestamp Logstash Parsing timestamp as UTC, so If your log format is like below and your timezone is UTC -8(PST), 2018-12-26T23:00:00-08:00, it will be handled by 2018-12-27 not 2018-12-26, because logstash uses UTC as timestamp.
  11. 11. Case #4 : Advance, multiple files to multiple files : with log timestamp How to fix?
  12. 12. Case #4 : Advance, multiple files to multiple files : with log timestamp filter { …… date { match => ["timestamp", "yyyy-MM-dd'T'HH:mm:ss-08:00"] Timezone => "UTC" } } Parsing timezone part as string, and set other parts as UTC
