Abstract: A system for diagnosing an information technology includes a collector server which stores configuration and event information gathered from the information technology environment and formats the information into formatted data. A data warehouse is in communication with the collector server and houses formatted data imported from the collection server. A portal server is in communication with the collector server and the data warehouse and has an interface from which the formatted data in the data warehouse can be viewed. In a service model, the collector server is located at a user site of the information technology while the data warehouse and portal server are located at a provider site remote from the user site. In a stand alone product model, the collector server, the data warehouse, and the portal server are all located at the user site.
