I am trying to import data from MySQL to elasticsearch using logstash, everything works fine and I have all the data imported well. However, one of the fields in MySQL called "metadata" is following a specific pattern like this "firstname\_lastname\_yyyy-MM-dd HH:mm:ss" so for example this is one of the values it may take "Mark\_Karlos\_2018-02-23 15:19:55", at the moment this field is imported to Elasticsearch as it is, what I want to do is to have this field as three fields in Elasticsearch "first\_name", "last\_name", "time". Is this possible to be done with Logstash config file? If not is there any other way to do this?

You can e.g. use a grok or a dissect filter.
