In gateway logs there is a MDC key **session-id** with a “short” id  
In a module which depends from **perspective** I would like to known how to add this mdc to the logger or if there is a specific logger class to use

Is it possible to obtain the “short” session-id from the

```auto
UUID sessionId = InternalSession.SESSION.get().getSession().getSessionId() ?

```

No, the `session-id` key is actually being set on the platform level in the webserver, not by Perspective. You would go to `GatewaySessionManager` on `GatewayContext`, find a session (the ID you’re getting from the `InternalSession` threadlocal should work) - then cast it to a `com.inductiveautomation.ignition.gateway.servlets.GWSession` and call `getPublicId()`.
