1. A method power management in a clustered system, the method comprising:
monitoring utilization among nodes of the clustered system;
balancing work loads among nodes of the clustered system based on the utilization monitoring, wherein the utilization monitoring comprises monitoring an idle node; and
avoiding activation of the idle node when there is no work request of the idle node based on the utilization monitoring of the idle node.
2. The method as claimed in claim 1, wherein the utilization monitoring comprises obtaining utilization information of the idle node solely when work is requested of the idle node.
3. The method as claimed in claim 1, wherein the utilization monitoring comprises packet sniffing for general node utilization information.
4. The method as claimed in claim 3, wherein said packet sniffing comprises
examining network packet content; and
modeling a request being processed by a node.
5. The method as claimed in claim 1, wherein the step of avoiding activation comprises avoiding individual polling of the idle node when there is no work request of the idle node.
6. The method as claimed in claim 5, wherein the step of avoiding individual polling comprises avoiding daemon-based polling of the idle node when there is no work request of the idle node.
7. The method as claimed in claim 5, wherein the step of avoiding individual polling comprises avoiding periodic polling of the idle node when there is no work request of the idle node.
8. A data processing system comprising at least a processor and a memory, further comprising a network monitor which monitors utilization among nodes of a clustered system; a load balancer which balances work loads among nodes of the clustered system based on monitoring by the network monitor; and the network monitor configured to monitor an idle node by avoiding activation of the idle node when there is no work request of the idle node.
9. The system as claimed in claim 8, wherein the network monitor is configured to obtain utilization information of the idle node solely when work is requested of the idle node.
10. The system as claimed in claim 8, wherein the network monitor is configured to employ packet sniffing for general node utilization information.
