Displaying alert / pop-up on client notebook window

[Abhinandan Dubey]

Hi guys,

]We have written a custom spawner for our organization to suit our use cases. In the same spawner, we have memory limits for every user, and this is checked within the poll() function, and logged on the server.

What I want to do is to display an alert to the client when he approaches, say about 90% of his memory limits, and another at 100%, displaying that the process is being killed.

Simply put : I need to display an alert message on client browser window through the poll() function

Is it even possible ?

Any help is appreciated, thanks !
