Abstract: Examples are generally directed towards a health check analysis for computing systems. On receiving health check data associated with a computing system, a health check server analyzes the health check data using a set of parameters to generate a health score and/or a status indicator for the computing system. The health check data includes performance data for a plurality of components of the computing system and/or configuration data for the plurality of components of the computing system. The health score ranks performance of the computing system relative to a scale. The status indicator identifies a health status of the computing system. A status indicator includes a normal status, a warning status, or a critical status. The server returns the health score and/or the status indicator to the user device for presentation to a user.

Abstract: Various embodiments are described herein for two-piece eye models for simulating an eye. The eye model generally has an eyelid member having a concave inner surface to simulate an inner surface of an eyelid; and an eyeball member having a rounded surface for simulating an eyeball and being sized to be releasably received within the concave inner surface of the eyelid member. Other embodiments may include at least one of an eye model holder, a fluidic system and an eye movement unit.
