I am new to Graylog. I have a Graylog setup for the production. I’ve send there an object which has been parsed into multiple fields. One of these fields has a type ‘keyword’, but now I would like to have a numeric data in this field so I can create a graph. Can I just start sending the numeric data into that field or I need to convert a field somehow?
a little more challenging, create a custom mapping in Elasticsearch where you force that field in that index to be numeric (be sure to rotate the index after setting up the custom mapping):
