Concurrent user visualization

Hi All

I want to know the number of concurrent user in my application over time, I log all login and logout for each user to Elasticsearch. How can I setup the visualization to achieve it ?

I don't believe you can do that in Kibana currently without calculating that data yourself and just graphing it. In order to get the active user count out of Elasticsearch using only the login and logout details, I'm pretty sure you'd need to use Pipeline Aggregations, which Kibana does not currently support.
