Abstract

Automatic configuration management of a network is provided by determining an inventory of resources at a virtualization layer of a node of the network, assigning prioritization to members of a set of network configuration elements, allocating virtual resources among the set of network configuration elements, establishing a network configuration. The configuration is managed by determining real time performance metrics for the configuration, producing a reallocation of the virtual resources based on the performance metrics that are estimated to change the established configuration, change the performance metrics, and initiating the reallocation of the virtual resources. This Abstract is provided for the sole purpose of complying with the Abstract requirement that allows a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

determining, using the controller that communicates with the virtualization layer, an inventory of network resources and virtual assets available to the virtualization environment;

provisioning, by the controller that communicates with the virtualization layer, the virtual assets from among the available inventory, thereby establishing a provisioned virtualization environment;

determining, at the controller, real time performance metrics for the provisioned virtualization environment;

receiving a Knowledge Block that specifies parameters that send an alert message to an administrator of the network in response to an alert condition and determines one or more reallocation parameters to be considered with the real time performance metrics in producing the reallocation of assets and wherein the Knowledge Block specifies parameters that detect operational degradation of a member of the available inventory which is halted and removed from the available inventory;

automatically determining at the controller for the provisioned virtualization environment under control of the controller, a reallocation of the virtual assets in response to the reallocation parameters and real time performance metrics;

initiating, by the controller that communicates with the virtualization layer, the reallocation of the virtual assets in the provisioned virtualization environment.

2. The method of claim 1, wherein the available inventory member that is detected as degraded is removed from the available inventory.

3. The method of claim 1, wherein the available inventory that is detected as degraded is moved from the available inventory to a debug inventory pool.

4. The method of claim 1, wherein log files are retrieved from the available inventory that is detected as degraded.

5. The method of claim 4, wherein the log files are stored in an archive and an alert message is sent to a network administrator with an identification of the log file archive location.

6. The method of claim 1, wherein the Knowledge Block specifies parameters that deploy an instance of an application selected from among the available inventory.

7. The method of claim 1, wherein the received user input specifies a priority for one or more of the available inventory.
