Logsatsh String To Date convertion

[haythem]

Hello Guys , so lately i've trying to insert some data from txt file into elasticsearch index , but i'm having a problem converting string field to date type , here is my logsatsh conf :

input {
 
file {
path => "C:/Elastic/Rapport_finale.txt"
start_position => "beginning"
}

}
 filter {
    
      csv {
	  separator => ";"
		 columns =>["ID","DATE_SITUATION","HEURE","COMPANY","NOM_COMPANY","DATE_SIT","NBRE_OPERATION_TOTAL","OPERATION_CAISSE","LR_LATITUDE","LR_LONGITUDE","SOMME","LIB_REGION","LIB_ZONE","LIB_AGENCE","DATE_UNIQ"]
		 
      } 
	  	  date {
        match => ["DATE_SIT", "yyyy-MM-dd HH:mm:ss"]
	
      }
	  
	
	  mutate {
   add_field => { "[location][lat]" => "%{LR_LONGITUDE}" }
   add_field => { "[location][lon]" => "%{LR_LATITUDE}" }
  }
   mutate {
    convert => {"[location][lat]" => "float"}
    convert => {"[location][lon]" => "float"}
   }
}
 

output{

  elasticsearch {
  hosts => "*.*.*.*:9200"
  index => "rapport_index_dg_finale_test"
  #document_type => "my_type"
  #action => "update"
  #doc_as_upsert => true
  #document_id => "%{id}"
  user => "logstash_admin"
  password => "********"
 }
 stdout{ codec => rubydebug}



 }

and this is the output in elasticsearch

any idea what am i doing wrong !!

elasticsearch version 7.4
logstash version 7.4

thanks.

In the rubydebug output does DATE_SIT look like this?

If it does then logstash has correctly parsed it and elasticsearch is converting it back to text because the field has already been mapped as text. Rolling over to a new index might help in that case.

@Badger i managed to fix my problem by adding this
date {
match => [ "DATE_SIT", "ISO8601", "YYYY-MM-dd HH:mm:ss", "YYYY-MM-dd HH:mm:ss.ZZZ" ]
target => "DATE"
locale => "en"
}
