Currently, it is only possible to set Alerts on raw metrics, but there are many cases where you would need to set an Alert on a Calculated Metric. This would greatly enhance the power of Alerts.
This is an important feature and I especially need an alert on Bounce Rates of specific pages. The Bounce rate is as important as the conversion rate and currently configured as [Single Access] / [Entries] . Setting-up an Alert is not possible at the moment.
Still waiting on this one. Wish it were possible...
This just surfaced for us as well recently-- would love to be able to do this without having to build something completely custom through the API.
We now have many calculated metrics for internal search, revenue and pathing reports. To be able to set alerts on calculated metrics will be a key for entire organization
