NWS: a complex resource monitoring tool

The components of a NWS resource monitoring system:

• a nameserver, a centralized controller, that keeps a registry of all the components and of the monitoring activities;
• the sensors, that produce resource availability measures;
• the memories, that store resource availability measures;
• the forecasters, that process resource availability measures;

Limits of the NWS architecture:

• a communication bottleneck;
• a single point of failure;
• no security;

Limits are bound to the design of the nameserver.
