I am parsing a log file which has error from 3 different process. I have added the input file in path and have added the 3 regex pattern in include line unique to 3 processes. Can I add field column which will be populated with the log line based on the regex pattern it matched in include\_lines tag? eg: logs are: [p1\_err] adc.... [p2\_err] adc.... [p3\_warn] adc.... [p1\_warn] adc.... [p3\_err] adc.... .... in my filebeat.yml filebeat.inputs: - type: log paths: - \ include\_lines: ['p1\_err', 'p2\_err', 'p3\_err'] I want to see the count of p1\_err,p2\_err,p3\_err lines in output on kibana. ---

`include_lines` is just for prefiltering, it's no parser. You can either go schemaless and use filtering on the "message" field in kibana UI in order to count events matching a pattern or use grok (Logstash or Ingest Node), or dissect (Filebeat or Logstash or Ingest Node) to do some minimal parsing. E.g. see [Filebeat dissect docs](https://www.elastic.co/guide/en/beats/filebeat/current/dissect.html). ---
