I am having an issue trying to get logstash to see the items in the array beyond the first item. the data will come in like. {"id": "430229930", "item\_tbl" :[{"itemid": 1,"itemname":"eggs","quantity": 10},{"itemid": 2,"itemname":"milk","quantity": 10}]} I can access the first item in the array by referencing [item\_tbl][0][itemname] I know the second item is [1] but how do I get logstash to mutate or manipulate all the items in the array? the documents will vary on the number of items in the array. ---

That depends on the filter(s) you want to use. Arrays of values aren't handled uniformly across all plugins. ---
