Abstract

Methods, systems and computer program products for operating a plurality of nodes within a network are provided. Using a monitoring node, a subgroup of the plurality of nodes is monitored, the subgroup including the monitoring node and a non-monitoring node. The non-monitoring node is configured to not manage a distributed database distributed among all monitoring nodes of the plurality of nodes, other non-monitoring nodes of the plurality of nodes, and the monitoring nodes of the plurality of nodes and is configured to not store replicated data from other ones of the plurality of nodes. Information from the subgroup is exchanged with a monitoring node of another subgroup of the plurality of nodes over the network, using the monitoring node.

Claims

1. A method for operating a plurality of nodes within a network, the method comprising:

monitoring, using a monitoring node, a subgroup of the plurality of nodes, the subgroup including the monitoring node and a non-monitoring node, the non-monitoring node configured to not manage a distributed database distributed among all monitoring nodes of the plurality of nodes, other non-monitoring nodes of the plurality of nodes, and the monitoring nodes of the plurality of nodes and configured to not store replicated data from other ones of the plurality of nodes; and

exchanging information from the subgroup with a monitoring node of another subgroup of the plurality of nodes over the network, using the monitoring node.

2. The method of claim 1, further comprising:

retrieving information from the non-monitoring node and storing the information to the distributed database.

3. The method of claim 1, further comprising:

retrieving information from the distributed database, in response to a query requesting a state of one or more nodes in the subgroup of the plurality of nodes.

4. The method of claim 1, further comprising:

performing a task retrieved from a task list in order to update the distributed database.

5. The method of claim 1, wherein the step of performing the task retrieved from the task list includes:

querying a node corresponding to the task in the task list, and

updating the distributed database with a status of the corresponding node, and retrieving new tasks from the task list.

6. The method of claim 1, further comprising:

detecting a non-operational node in the subgroup, and

conveying a status of the non-operational node to a management computer.

7. The method of claim 6, further comprising removing the non-operational node from the task list.

8. A system for operating a network, the system comprising:

a plurality of nodes including at least one subgroup including a monitoring node and a non-monitoring node, the monitoring node including;

a processor device, and

a memory including instructions stored thereon which when executed by the processor device causes the monitoring node to;

monitor the subgroup of the plurality of nodes, the subgroup including the monitoring node and the non-monitoring node, the non-monitoring node configured to not manage a distributed database distributed among all monitoring nodes of the plurality of nodes, other non-monitoring nodes of the plurality of nodes, and the monitoring nodes of the plurality of nodes and configured to not store replicated data from other ones of the plurality of nodes; and

exchange information from the subgroup with a monitoring node of another subgroup of the plurality of nodes over the network.

9. The system of claim 8, wherein the memory further comprises instructions stored thereon which when executed by the processor device causes the monitoring node to:

retrieve information from the non-monitoring node and storing the information to the distributed database.

10. The system of claim 8, wherein the memory further comprises instructions stored thereon which when executed by the processor device causes the monitoring node to:

retrieve information from the distributed database, in response to a query requesting a state of one or more nodes in the subgroup of the plurality of nodes.

11. The system of claim 8, wherein the memory further comprises instructions stored thereon which when executed by the processor device causes the monitoring node to:

perform a task retrieved from a task list in order to update the distributed database.

12. The system of claim 8, wherein the memory further comprises instructions stored thereon which when executed by the processor device causes the monitoring node to, as part of performing the task retrieved from the task list:

query a node corresponding to the task in the task list, and

update the distributed database with a status of the corresponding node, and retrieve new tasks from the task list.

13. The system of claim 8, wherein the memory further comprises instructions stored thereon which when executed by the processor device causes the monitoring node to:

detect a non-operational node in the subgroup, and

convey a status of the non-operational node to a management computer.

14. A computer program product for operating a plurality of nodes within a network, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable code portion for monitoring, using a monitoring node, a subgroup of the plurality of nodes, the subgroup including the monitoring node and a non-monitoring node, the non-monitoring node configured to not manage a distributed database distributed among all monitoring nodes of the plurality of nodes, other non-monitoring nodes of the plurality of nodes, and the monitoring nodes of the plurality of nodes and configured to not store replicated data from other ones of the plurality of nodes; and

a second executable code portion for exchanging information from the subgroup with a monitoring node of another subgroup of the plurality of nodes over the network, using the monitoring node.

15. The computer program product of claim 14, further comprising:

a third executable code portion for retrieving information from the non-monitoring node and storing the information to the distributed database.

16. The computer program product of claim 14, further comprising:

a third executable code portion for retrieving information from the distributed database, in response to a query requesting a state of one or more nodes in the subgroup of the plurality of nodes.

17. The computer program product of claim 14, further comprising:

a third executable code portion for performing a task retrieved from a task list in order to update the distributed database.

18. The computer program product of claim 14, wherein the third executable code portion includes:

executable code for querying a node corresponding to the task in the task list, and

executable code for updating the distributed database with a status of the corresponding node, and retrieving new tasks from the task list.

19. The computer program product of claim 14, further comprising:

a third executable code portion for detecting a non-operational node in the subgroup, and

a fourth executable code portion for conveying a status of the non-operational node to a management computer.

20. The computer program product of claim 19, further comprising a fifth executable code portion for removing the non-operational node from the task list.
