HELP regarding NWM 7.1 Statistics and alerts

Hi experts,

I am looking for a proper explanation of NWM 7.1's alert functionality. I think it needs to be configured on WAS, right ? and the thing i want to know is that whether a user can set alert for any variable of his choice in middleware.?

I mean, a value of any variable, say no. of Service Orders goes beyond a specific limit then he should get an alert on frontend(client). Is it possible, and if yes, how ?

Does anyone have a proper document explaining this thing in detail?? In what form are alerts given to an user.?

Please guide me further.

thanks & regards,
