Abstract
A method, computer program product, and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to track performance and reliability statistics per virtual upstream and downstream port, thereby allowing a system and network management to be performed at finer granularity than what is possible using conventional physical port statistics, is provided. Particularly, a mechanism of managing per-virtual port performance metrics in a logically partitioned data processing system including allocating a subset of resources of a physical adapter to a virtual adapter of a plurality of virtual adapters is provided. The subset of resources includes a virtual port having an identifier assigned thereto. The identifier of the virtual port is associated with an address of a physical port. A metric table is associated with the virtual port, wherein the metric table includes metrics of operations that target the virtual port.
