Patent ID: 8051173

Claim:
A monitoring device in a node in a cluster system for monitoring at least two resources to be monitored at the node of the cluster system, wherein a dynamic priority can be allocated to the resources to be monitored, the monitoring device comprising: a selection device operable to select one resource from the at least two resources located on the node of the cluster system and assigned to be monitored on the basis of the dynamic priorities assigned to the resources to be monitored; at least one monitoring detector suitable for monitoring the resource located on the node of the cluster system and assigned to be monitored; an allocation unit operable to allocate the monitoring detector to the resource located on the node of the cluster system and assigned to be monitored; and a running device operable to run the monitoring detector during a time interval such that, once the resource located on the node of the cluster system and assigned to be monitored has been monitored by the monitoring detector, the running device terminates running of the monitoring detector and increases the dynamic priority assigned to another resource that has not been monitored during the time interval.
