A method includes receiving tool trace data from a group of tools of the same type in a computing device. A tool fingerprint is generated for each tool using the tool trace data for the tools in group other than the tool for which the tool fingerprint is generated in the computing device. A tool score is generated for each tool based on its tool trace data and its associated fingerprint in the computing device. A fault condition with at least a selected tool is identified based on the tool scores in the computing device. |
