Hi Tonia, my apologies, it appears that no one has addressed your question since the forum was changed to the new community.
Prognosis does not have a specific failover alert for pub>sub failover however we do have a series of alerts that should provide a good indication when this happens. First would be the cmaDeviceAlerts threshold which has triggers for phone de-registration. Specifically the condition 'CmaPhoneRegChange'. By default this is designed to alert when there is a de-registration or registration of more than 50 phones. Next is the cmaServerAlerts threshold which alerts when any cluster server goes offline.
you can read more about each of the Cisco alerts within online help here:
Prognosis for Unified Communications > Cisco Unified Communications Manager > Thresholds and Alerts
