im running a Java web application based on Playframework 2.5.4 and Apache Webserver.In some cases (e.g. software patching processes) i need to stop the running application. For this i must be shure, that no open connections are currently available (no users are using the plattform).Is there an elegant (build-in) way to get the count of all currently opened connections in Play or on the Apache Server ? It would be nice the print the count of opened connections on a view on the application platform.
