There doesn't appear to be an out the box template for this. For anyone with HA pools configured the way we have worked round this is by monitoring the VIP with the Orion Observability template, adding in the MPE/APE with it's own static IP without any applications assigned, and then monitoring the standby server with this template.
We then have a separate alert to trigger if the sevices monitored on this template go down. We want to pre-empt any problems with the standby that may prevent successful failover occuring.
Hope this helps!
