Hello Everyone,

I am attempting to get some information about the perspective session from a shared script. Is there a way to access the session props from the system scripts library? I have tried `system.perspective.getSessionInfo`, but it gives a list of all the sessions. I tried using `system.security.getUsername` to lookup the correct session, but that function is not in the perspective scope. (I am also interested in the gateway address, but `system.util.getGatewayAddress` is also not in perspective scope for some reason.) I know I can pass the session object from a component scope, but that would require a lot of refactoring. Is that really the only way?

To get information about a specific session which is invoking the project script, you’ll need to pass the session into the script as an argument. I know you’re trying to avoid the refactor, but if you want that info then you need to pass something which has that info.

```auto
def my_proj_func(session):
    system.util.getLogger('SessionIPLogger').info(session.props.host)

```

Passing the session object is the only _supported_ way. There _is_ a gross hack you can do, but as mentioned in the thread, don't expect support or be surprised if it breaks suddenly on upgrade.

> In theory, the InternalSession.SESSION [ThreadLocal](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/ThreadLocal.html) would be populated if you’re running a project script from a Perspective thread; so something like this might work: from com.inductiveautomation.perspective.gateway.session import InternalSession session = InternalSession.SESSION.get() if session is not None: system.perspective.print(session.custom.something)

Always fun to see myself in a link about unsupported or non recommended techniques (:

This is promising, however it seems that it has broken already. I’m running 8.1.8 and getting this error when attempting that solution: `com.inductiveautomation.ignition.common.script.JythonExecException: ImportError: No module named perspective`

I would only expect it to work if invoked from a Perspective calling context, but even then it’s possible that classloader restrictions on the gateway are such it won’t work anyways.
