1. A method for recognizing an occurrence of a transaction that is defined by a sequence of one or more service requests, comprising:

  • reading a service request that is transmitted between two computational components, the service request comprising at least a portion of a request by a first of the two computational components for processing by a second of the two computational components;

    normalizing the service request into a service request representation to remove at least some service request-specific information from the service request;

    combining the representation of the service request with a plurality of other service request representations to form a string of service request representations; and

    automatically comparing the string of service request representations with a predetermined regular expression characterizing the transaction to determine if the string of service request representations corresponds to an occurrence of the transaction.
