Getting into Ganglia for a scalable and flexible solution to the problem of cluster monitoring.

Monitoring the status of a Beowulf-style cluster can be a daunting task for any system administrator, especially if the cluster consists of more than a dozen nodes.

Luckily, some sort of statistical resource monitoring can often yield early warnings of impending hardware failures.
