Abstract

A technique for monitoring operational parameters of networked components includes storing data within each component descriptive of the component. The data is polled by a monitoring station and provides a basis for monitor views compiled in real time. The monitor views provide a view of current levels of parameters controlled or monitored by each device, such as on virtual meters. Historical levels of operational parameters may be presented in virtual strip chart output. Textual descriptions of the components are provided, along with listings of key settings. More detailed data may be accessed by links between the monitor views and other user viewable representations for the system and the specific components.
