I have some cleanup code that runs when a perspective user logs out (via a log-out button), but this code doesn't execute on a session closes unexpectedly. I'd like to instead run this code on the gateway when a session ends or is lost. Is there an easy way to trigger this script? My initial though is to setup a session message and let the gateway run the code if it misses X number of messages from a given session. That seems overly complex for what I'm trying to do, so I'm hoping that there is an easier event driven in way that I don't know about. ---

Perspective session messages are sent from the gateway (any script that could send one has to run on the gateway in Perspective) so it wouldn't work as a heartbeat to detect browser connection loss. The session shutdown event does eventually detect disconnection, but it takes time: > [@Understanding perspective session events](https://forum.inductiveautomation.com/t/understanding-perspective-session-events/23328/3): > > Closing a browser window doesn’t kill your session - it remains alive for 120 (maybe 60?) seconds by default, which can be configured here, in the Session Timeout section: So you won’t see the “end\_session” message sent from the Perspective Session for at least one minute, maybe two. I’ll look into the device\_id being empty, but I just tested it myself and it worked as expected… More discussion on the topic, including a link to a relevant feature request: > [@Detecting lost connection to the gateway](https://forum.inductiveautomation.com/t/detecting-lost-connection-to-the-gateway/78502): > > We are testing how perspective clients react to a communication loss to the gateway due to a cable break or the gateway loosing power. We observe that it takes 2,5 minutes before the client displays the "No Connection to Gateway" banner.

Any reason a session shutdown event would not work? > **[Perspective Session Event Scripts | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/perspective/scripting-in-perspective/perspective-session-events-scripts#startup-and-shutdown-event-scripts)** > > Perspective offers a collection of Session Events designed to allow the Gateway to track and interact with the Session at critical moments. Specifically, they are scripts that run in the Gateway when a Session starts up, shuts down, or runs a Native... It would not detect the browser closing right away (rather after the session timeout), but it **would run** once the session properly ends. ---

Thank you for the advice. I'll try the Session Event and see if that fixes my problem. I forgot it runs on the Gateway in perspective therefore it should still run.
