My field contains multiple values, which separated by comma. How can I split the each comma separated values and put on the same filed name.
Ex.
The consider the below field and values,
SerialNumber =\> [abc23, cde56, mgf78]
I am looking to split them to,
MySerialNymber =\> abc23,
MySerialNymber =\> cde56
MySerialNymber =\> mgf78

For an event to have multiple values for a single field name the field has to be an array, you cannot have more than one field on an event with the same name.
If you have an array field and you want to split it into multiple events then you can use a [split](https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html) filter.
