Abstract: A storage system includes a host, and a storage device configured to receive, from the host, a plurality of first type commands, measure a plurality of latencies of the plurality of first type commands, count a number of occurrences of the plurality of latencies within a first time period, the first time period being a time length among the plurality of latencies, generate latency data including time points when each of the plurality of first type commands are received, based on the number of occurrences exceeding a predetermined threshold value, and output, to the host, the latency data based on an asynchronous event request (AER) command being received from the host.

Abstract: A host system includes a host device configured to generate a first log, a storage device configured to generate at least one second log, and a shared memory configured to store the first log and to store composite logs corresponding to the first log and the at least one second log. The storage device reads the first log from the shared memory, adds a timestamp and log-type information to the first log and the at least one second log to generate the composite logs, and writes the composite logs to the shared memory.
