A method and program product for receiving an indication of a particular root cause associated with an error condition in an information technology (IT) system, electronically capturing activity of an operator for the IT system, automatically generating a workflow portion for a generic runbook, and storing the generic runbook in a manner that allows retrieval of the generic runbook.

Automating the production of runbook workflows

A method, apparatus and computer-program product for mapping and identifying resources in network based services is disclosed. The method comprises the steps of determining a measure of utilization for each of the selected transactions, generating an indication for each measure of utilization exceeding an associated utilization threshold value, determining the cause of the measure of utilization exceeding the associated utilization threshold value by correlating the transactions generating the indications with the resources executing the transaction and applying additional resources until the measure of utilization is less than the associated threshold. In one aspect of the invention, balancing the measure of utilization associated with each of the selected transactions occurs to maintain each of the measures of utilization within a substantially known tolerance to each other measure of utilization.

A generic analysis model is applicable to a variety of network infrastructure domains, and operable for causal analysis in a common manner independently of the corresponding underlying domain. The generic analysis model may be employed to model root cause analysis and impact analysis for different resource management systems such as enterprise networks, storage area networks, service provider networks and business process management. Such a model improves performance and scalability by simplifying analysis model for a given solution, and decouples the development from topology building and analysis implementation.
