The Device Health dashboard provides an overall view of the health and performance of
        your NGFW devices.
    Maintaining optimal health and proactive performance across numerous NGFW devices can be
            challenging. The 
Device health dashboard in 
Strata Cloud Manager shows you the cumulative health status and performance of your onboarded NGFW
            devices. The device health is determined by the severity of the health score (0-100) and
            its corresponding health grade (good, fair, poor, critical). The health score is
            calculated based on the priority, quantity, type, and status of the open alerts.
