Having log lines like: `id: 123 message: start processing @timestamp: Jul 7, 2020 @ 02:10:02.866` `id: 123 message: finished processing @timestamp: Jul 7, 2020 @ 02:12:02.866` So I want to make a graph where I display the proccessing time. ( 2 minutes ) in this case. Any why I can do this with Kibana? ---

That's a particular problem, not possible for Kibana with how your data is indexed. You would need to index the data where the start-and finish are a single document, with the time-difference being a single value, and a single `id` field. I would create an ER here, as I feel like this question comes up occasionally: [https://github.com/elastic/kibana/issues/new](https://github.com/elastic/kibana/issues/new) ---
