Analyzing information technology systems using collaborative intelligence data anonimity

An information technology (IT) system of interest is analyzed using collaborative, community-based sharing of expert knowledge, analysis and advice through user-submitted analysis rules and/or user-submitted report templates. Users may submit rules that have been found to be useful in analyzing or managing IT systems. A rule may analyze a particular item of configuration data or performance data according to a predetermined criterion. Other users may apply these rules to their own systems' data and, thereby, utilize the collective expertise of the people who submitted the rules. Performance and configuration data from IT systems or components of the systems in various enterprises is collected and then sanitized by removing or masking identifying information before storing the sanitized data in a data warehouse. An IT manager may compare data from his/her IT system to historical data from the system or to data from IT systems having similar workloads, configurations, problems or according to other matching criteria, without obtaining confidential information about the comparison systems. Such comparisons may use the user-submitted rules. Reports are generated from these analyses and comparisons according to predefined and/or user-submitted report templates and report component templates for items such as text blocks, tables, graphs, charts and block diagrams.
