I want to extract date from a log file to another field in elastic search that is coming through logstash. My log file is like this
21 May 2018 12:13:32,025 INFO [org.jboss.as.configadmin] (ServerService Thread Pool -- 26) JBAS016200: Activating ConfigAdmin Subsystem
What I want is get the date field extracted using logstash and save it to elastic search. Any help would be appreciable.
