App monitors are very useful for seeing an aggregation of failures or impact based on a set of checks and groups. App monitors typically correlate to Apps provisioned from Morpheus Blueprints but can also be manually created and organized. They can be great for visualizing the customer impact a failure might have or even keeping up on a screen in a NOC. To create an App monitor:

A friendly name for the new app monitor in Morpheus
An optional description value to identify the app monitor
Max Severity
The maximum severity incident a failed app may create. This setting overrides check and group max severity settings
Affects Availability
When checked, this failed app impacts system-wide availability calculations
App Checks
Use the typeahead field to select as many checks as needed to complete the app monitor. Checks are created in Monitoring > Checks and must exist prior to creating the app monitor
