Hi, I'm trying to create a data table visualization that will return records for services that are no longer sending a heartbeat. For example Service 1 was sending a heartbeat then stopped 5 minutes ago. There's not a top-level field that I can key off to use a NOT EXISTS clause. So I was considering querying for a documents that match `routing_key: service.heartbeat`then returning all services that have a timestamp older than 5 minutes but not records that have a timestamp less than 2 minutes old. I've tried leveraging MAX bucket and a time range but it doesn't want to work for me. Any suggestions on how to approach this would be much appreciated!

Have you tried using the [uptime application](https://www.elastic.co/guide/en/kibana/current/xpack-uptime.html) to view service status? Uptime will show you when services have not received heartbeat messages.
