The monitoring of Grid components can be
performed using either push or pull models. The push model of execution
is where the monitored component sends data to the monitor when an
event occurs or after a defined time period. The pull model is when the
monitor polls the information source for its data.
Grid push model monitoring systems include Ganglia and MDS2. Grid pull
model monitoring systems include NWS and Remos. [Zanikolas:2004] |

Information gathering characterizes an approach used
to collect and if necessary to aggregate data from various information
sources. One can distinguish between polling mode of
information gathering, when, e.g., the sources are periodically
queried, push mode, when the information gathering is
event-driven, or more sophisticated simulation mode: a certain
model of the monitored property continuously evolve on the basis of the
information and events collected in either of the two previous modes.
