Am trying to get a sum value of CPU USER and CPU SYSTEM percentage thru Ruby client. Is there any single API parameter to pull out the both the values ? I believe, it does have 2 separate parameters. I wanted to check, cpu load (system+user) have crossed 85%, if yes, how many instances. Please let me know. ---

I was thinking you could use a script query for that to add the two fields together? [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-script-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-script-query.html) Not 100% sure if this will work so best try it first out in the console and then translate it to a ruby query. ---
