Abstract
A storage controller system is provided for the monitoring of fast path processing of I/Os to a storage device where the storage controller system allows for processing of I/Os to be monitored through the use of counters in a storage controller based upon the type of I/O issued to the storage controller as well as the conditions associated with the I/O, while providing a bitmap and associated divert bits and counters to monitor the processing of the I/Os in the storage controller. Methods for monitoring the processing of I/Os issued to the storage controller are also provided where the processing of the I/Os is based upon the type fast path I/Os issued to the storage controller and the conditions associated with the issued I/Os while providing a bitmap and associated divert bits and counters to monitor the processing of the I/Os in the storage controller, are also disclosed.
