Resource Management

Resource Management Service stores all the information about the resource types and their instances that are discovered from the network. The discovery is performed by SNMP Discovery from SNMP-enabled devices, Flow Collector for Flow-enabled devices, and File Collector for file-based devices. Resource Management is associated with the Inventory Service in Telco Network Cloud Manager - Performance system.

All the discovered Resource types are sent to Resource Management. The following tasks are handled by Resource Management:

Validates if the resource types contain valid properties or not.
Stores the resource types and their relations in Cassandra database for future query.
Stores the history of resources.
Broadcasts the discovered or updated resources to subscribers.
Handles queries on resource types and relations.

All the services that need resource types information either query or subscribe to the Resource Management Service. Any update on the resource types is broadcasted to the subscribers. This way, the subscribers can respond to the availability of any new resources.

Resource Management stores both physical and logical resources (region and site). The logical resources can be defined through the model files that are configured in Technology Packs.

A GenericGroup type is added by default to the system whereby you can place resource types in a static group without the need for an associated model.
