Claim Text:
1. A method for passively monitoring a computer system, comprising: accessing a virtual server by an indexing agent external to the virtual server, the indexing agent comprising: retrieving a virtual image of the virtual server by the indexing agent; indexing, for each of the plurality of indexing layers, a corresponding abstraction level of the virtual image by the indexing agent to extract abstraction level features indicative of changes in the virtual server relative to a pre-configured software stack, the indexing including the first indexing module providing instructions to the indexing agent while the first indexing layer is indexing a first abstraction level of the virtual server indexed by the first indexing layer; in response to completion of the indexing by the first indexing module, indexing a second abstraction level of the virtual server indexed by the second indexing layer using instructions provided by the second indexing module to the second indexing layer; and analyzing at least one of the abstraction level features to perform passive monitoring of the virtual server.
