Embodiments of the present invention provide an approach for an image provider to specify data (e.g., commands to run, files to read), etc., about an image of a virtual resource (e.g., virtual machine, etc.) in a networked computing environment (e.g., a cloud computing environment). Such data may be used (e.g., at runtime) by a client application to obtain specific information about a running instance that is provisioned based on the image (e.g., operating system health, middleware health, etc.).
