I have a few devices that periodically send data to elasticsearch. If the devices send data that indicates them as offline I have an elapsed_filter that waits until it sends data indicating it is online again. I end up with a document that has the fields "last_online", "time_offline", "current_time".
My question: Is there a way to visualize this data in such a way I can see the time when the device is offline until it is online again? Currently it seems I can only do this if there are multiple documents, otherwise I can only get 1 point of time on the graph.
Thank you. Any help is appreciated.
