Hi, at login our user gets a static session id which is valid until logout / timeout. I want to analyze how long our users are logged in. What possibilities do I have to do so? Is it possible with post processing or is my only option save these informations by session id at index time in a separate entity centric index with session id as key? Thanks, Andreas ---

You can use the data transformation APIs to do this. They were introduced as "data frames" in 7.2.0 and are now called "data transforms" [https://www.elastic.co/guide/en/elasticsearch/reference/current/transforms.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/transforms.html) ---
