Patent ID: 8478888

Claim:
A resource monitoring method, comprising: detecting, by at least one processor, a resource to be monitored by a first monitoring node in a resource monitoring cluster, the resource monitoring cluster having a plurality of monitoring nodes including at least the first monitoring node and a second monitoring node, wherein the first monitoring node has a namespace including an overlay namespace and a local namespace, the local namespace including at least one first object of a first monitored resource by the first monitoring node, the overlay namespace including links to namespaces of other monitoring nodes in the resource monitoring cluster including a link to a namespace of the second monitoring node, the link including a local viewpoint of the namespace of the second monitoring node providing at least one second object of a second monitored resource by the second monitoring node; issuing, by the at least one processor, a creation request for creating an object for the resource to be monitored by the first monitoring node to the plurality of monitoring nodes having linked namespaces in the overlap namespace; receiving, by the at least one processor, responses to the creation request from the plurality of monitoring nodes having the linked namespaces in the overlap namespace; determining, by the at least one processor, the allowability of the creation request based on the responses; creating, by the at least one processor, the object for the resource to be monitored by the first monitoring mode if determined to be allowable; and mapping, by the at least one processor, the created object to the local namespace of the first monitoring node.
