Tracking and factoring application near misses/timeouts into path selection and multipathing status

Abstract:

Various embodiments for management of multipath Input/Output (I/O) in a computing system by a processor device. Upon surpassing a threshold for at least one predetermined criterion associated with near timeouts/near misses in the multipath I/O, a system notification is provided that is usable by the processor device to perform a multipath layer path selection aimed at reducing near timeouts/near misses in the multipath I/O.
