Hello All,

I've a column in oracle table PACKAGE_DATA and it has json like string in it and I would like to get every fileds and its value seperate:

PACKAGE_DATA Column data

{"status":"READY_FOR_PROCESSING","errorData":null,"creationDate":1678096719969,"lastModificationDate":1678096824967,"manyId":"1900","form":"ABC","systemId":"TIS_FULL","userId":"?","XmlFileId":"","size":0,"Kind":"FULL","Datas":[{"serviceRequestId":"29F91450A3","Counter":2,"size":122628,"fileId":"CC2B5","packageId":"1900","lPart":true},{"sRequestId":"190FBB14E1864A75B6B8ECC054FEAD3A","pCounter":1,"size":122628,"fileId":"F6395CF76A2E","packageId":"1900","lastPart":false}],"Histories":[{"status":"START","errorData":null,"creationDate":1678096719980,"lastModificationDate":1678096719980},{"status":"PROCESSING","errorData":null,"creationDate":1678096824974,"lastModificationDate":1678096824974}]}

Expected individual fields in elastic index:
"status":"READY_FOR_PROCESSING",
"errorData":null,
"serviceRequestId":"29F91450A3",
"Counter":2,
"size":122628,
"fileId":"CC2B5".............etc

Tried Filters:

1)With this in logs I can see only sql query statement in log ,but data dont come to index

json {
source => "package_data"
}

filter {
  json {source => "package_data"} 
        split {field => "package_data"}
        mutate {remove_field => [ "package_data"]}
}
