Is there a way to set up alerts that are emailed when certain performance thresholds are reached for applications specified?    For example, could an alert be sent when the Page Views or Load Time as reported in Lifetime exceed a pre-determined limit for the applications selected by the recipient?

This would be similar functionality to emailing the performance reports from the Performance tab in lifetime.  

Thanks for your help.
You could build something with the Lifetime SDK, but there is not something built-in.
