We describe the CARD (Cluster Administration using Relational
Databases) system for monitoring large clusters of cooperating
computers. CARD scales both in capacity and in visualization to at
least 150 machines, and can in principle scale far beyond that. The

faults. CARD uses a Java applet as its primary interface allowing
users anywhere in the world to monitor the cluster through their
