Abstract: The present invention relates to a system and corresponding computer-implemented method for identifying exceptions in behavior of a computer system or of an application executed on the computer system. The system comprises: a component for building at least one pattern from monitored signals over a specific time period whereby the pattern is an exception identified via signal constellation out of system-side recorded resource usage data and measured energy consumption data of the entire computer system, a component for identifying an exception by comparing the at least one pattern with one or more afore built patterns each labelled with a pre-defined exception classification, a storage component for storing at least one compared, unmatched pattern for subsequent exception identification, wherein the unmatched pattern is labelled with any pre-defined exception classification via user interaction, an output component for outputting an alarm message onto an output device if any compared pattern matches.

Abstract: Various embodiments of the teachings herein include a method for identifying/detecting non-qualified services in a network of distributed services. In some embodiments, the method includes: detecting comparative interaction patterns between at least two services in a contract; observing interaction patterns during the communication of the services; and comparing the observed interaction patterns with the comparative interaction patterns.
