A network appliance for monitoring, diagnosing and documenting problems among a plurality of devices and processes coupled to a computer network utilizes periodic polling and collection of object-generated trap data to monitor the status of objects on the computer network. The golf ball of the present invention combines lower dimple count with multiple dimple sizes to provide higher dimple coverage and improved aerodynamic characteristics. A vibrator mechanism can be employed to transmit vibration to the supply and thereby facilitate an even distribution of rock dust in the supply and a smooth and continuous flow of rock dust as rock dust is drawn from the supply. The closure includes a top portion, a first skirt extending from the top portion, and a second skirt extending from the top portion. Diopter power and base in prism gradually increase from the distance portion to the near portion.
