END-TO-END IT SERVICE PERFORMANCE MONITORING

A layout is generated of an end-to-end IT service. The layout identifies components of the end-to-end IT service and includes a physical layout and a logical layout. The layout is divided into smaller blocks. Each smaller block represents a function or a set of functions. Interactions for aggregation points between two or more blocks are identified. Using probes placed at aggregation points in the end-to-end IT service, performance of each interaction is measured at each aggregation point. Placement of the probes is optimized based on the interactions. Output is provided that includes information indicating measured performance of the interactions, including prioritized information for measured performance of anomalies.
