An information source is anything that can produce monitoring information. Typical Grid information sources are processors, memories, storage media, network links, applications and processes. [Zanikolas, 2004] [PO-JRA-2.3.1] | ||||
Generic (domain independent) |
Information sources represent various components and entities that provide all the data, which is used by the monitor in order to evaluate the monitored properties. These sources may range from rather basic elements (such as messages, log files, or timers), to more complex monitors based on top of them (sensors, probes), to hierarchically complex monitoring systems, thus providing recursive and reusable monitoring solutions. In other words, one monitor may re-use another monitor as a source if information, where the information are the events reported by the latter. [CD-JRA-1.2.2] | An information source is a source of information for somebody, i.e. anything that might inform a person about something or provide knowledge to somebody. Information sources may be observations, people, speeches, documents, pictures, organizations etc. They may be primary sources, secondary sources, tertiary sources and so on. [Wikipedia] |
