A system and method for automatically and adaptively capturing, recording, and retrieving large amounts of complex Information Technology (IT) system component state data in a distributed, hierarchical manner. Monitored components include virtually any element in an IT system, including hardware, e.g., routers, hard drives, etc., and software, e.g., databases, operating system, kernels, etc. In a preferred embodiment, collection and storage elements, or objects, are logically arranged in a hierarchical manner such that data collected may be propagated up in the hierarchy. Similarly, querying of such data is performed in a hierarchial manner, e.g., queries are propagated down and results propagated up. Propagation of collected data through the storage system is performed in a manner to optimize system performance. Uniformity in the collection and storage scheme allows easy expansion of the collection and storage system, and thus the underlying IT system infrastructure. |
