Abstract: A method to manage performance monitoring and problem determination in a context of a service application is provided. The method includes distributing performance monitoring reusable templates to the computing system that describe a set of required monitoring products, a set of scenarios with key performance indicators (KPI) relevant to the service application, and a set of best practices solutions describing how a potential performance incident is to be handled, during instantiation of the service application, deriving from the reusable templates actual performance monitoring characteristics related to various selected components of the computing system, and customizing the reusable templates to the service application in accordance with the actual performance monitoring characteristics by determining whether a number and a type of monitoring agents and/or scenarios with associated KPIs are to be changed, determining whether different KPIs exist and by determining whether solutions exist for an incident.

Abstract: An impact of configuration changes on controllers is projected, in a computing environment including one or more bridge attached channels. This projection quantifies the impact for each controller affected by the change, such that it is known by a quantifiable value how much the change impacts the controller. In order to project the impact, a projected I/O velocity of the controller is determined. In making the projections, pseudo channels associated with a particular bridge attached channel are modelled as independent channels. Alternatively, a utilization metric of a bridge attached channel is determined and compared to a threshold; pseudo channels associated with the bridge attached channel are modelled as independent channels if the utilization metric is below the threshold.
