Create a new filed from a string field in painless script/ Substing in painless

I have a string field message in filebeats index

message : "2018-12-07 00:42:57,797;INFO ;ATDSDSFCMTWB03.6612.38.0.0a7eec05-287d-462e-b2b5-bab666ee33e6;1;0;;GetSiteDetailsHandler;2;"

I need to split the string & extract the last integer(which is 2 here) and assign it to a new field .

I know we need to use scripted field(painless script) for this case .

Can someone please suggest painless script query to do this.

I would suggest you split up the message while ingesting events using Filebeat into Elasticsearch. To do this, you will first want to define an Elasticsearch Ingest Node pipeline with the right sequence of processors to perform the splitting of the message field and extraction of the last field from the resulting array. Then you will want to reference this pipeline in your filebeat.yml via the output.elasticsearch.pipeline setting.

Thanks I will try this .
