Abstract
A method of providing synchronized operational information for a host computer and an attached storage system is provided. The method includes providing a trace buffer in a memory of the storage system. A special command is created which allows a host computer to write information to the provided trace buffer. The special command uses a command from the communication protocol command set is a specific way in order to effectuate the trace buffer entry. The trace buffer entry will have a time component based on the storage system time clock. Thus, host activity may be synchronized in time with the storage system activity. In addition to the trace buffer, a statistics table is provided which maintains a log of which applications programs running on specific hosts, accessed the devices of the storage system.
