Computer system model generation with tracking of actual computer system configuration
View Patent ↗The present invention provides a system and method for generating models of a computer system. The method involves generating an original model of a computer system in an original configuration, and performing an original series of changes of the original model to yield an intermediate model. The original series of changes is recorded. The method further involves tracking the actual configuration of the computer system so as to detect a revised configuration of the computer system. Then, a resultant model is generated that corresponds to the computer system in a potential resultant system configuration that would result from a series of reconfigurations corresponding to said original series of changes or a revision thereof being applied to the system in its revised configuration rather than in its original configuration.
1. A method comprising:
computer-generating an original model of a computer system in an original configuration;
performing an original series of changes to said original model to yield an intermediate model that corresponds to a potential configuration of said computer system but does not correspond to a past or current actual configuration of said computer system;
recording said original series of changes;
tracking the actual configuration of said computer system so as to detect a revised configuration of said computer system, said revised configuration being different from said original configuration;
computer-generating a resultant model corresponding to said computer system in a potential resultant system configuration that would result from a series of reconfigurations corresponding to said original series of changes or a revision thereof being applied to said system in said revised configuration.
2. A method as recited in claim 1 further comprising:
determining whether or not said original series of changes is consistent with said revised configuration, said series of reconfigurations corresponding to said original series of changes if said original series of changes is determined to be consistent with said revised configuration.
3. A method as recited in claim 2 further comprising, in the event that said original series is determined to be inconsistent with said revised configuration, revising said original series of changes so that said series of reconfigurations corresponds to said revision of said original series of changes.
4. A method as recited in claim 1 further comprising passing said resultant model to a simulator to perform a simulation of said resultant model.
5. A method as recited in claim 1 further comprising passing said resultant model to an implementer to perform an implementation of said resultant model so that said system is reconfigured to assume a resultant configuration corresponding to said resultant model.
6. A system comprising
a configuration tracker for detecting configurations of a computer system, said configurations including an original configuration and a subsequent revised configuration;
an interface permitting a user to apply an original series of changes to an original model to yield an intermediate model that corresponds to a potential configuration of said computer system but does not correspond to a past or current actual configuration of said computer system;
recorder means for recording said original series of changes; and
a model generator for generating said original model and a resultant model of said computer system, said original model corresponding to said original configuration, said resultant model corresponding to a resultant configuration that would result from a series of reconfigurations corresponding to said original series of changes or a revision thereof being applied to said computer system starting from said revised system configuration.
7. A system as recited in claim 6 wherein:
said model generator determines whether or not said original series of changes is consistent with said revised configuration; and
said interface permits a user to modify said original series of changes to yield said revision of thereof.
8. A system as recited in claim 6 further comprising a simulator for performing a simulation using said resultant model.
9. A system as recited in claim 6 further comprising an implementer for implementing said resultant model so that said computer system assumes said resultant configuration.
