Read B/s Shown by the all parameter. Data transfer rate, in bytes per second, for read operations since the last sampling time. Write B/s Shown by the all parameter. Data transfer rate, in bytes per second, for write operations since the last sampling time. Queue Depth Shown by the all parameter. Average number of pending read and write operations being serviced since the last sampling time. This value represents periods of activity only and excludes periods of inactivity. I/O Resp Time Average response time, in microseconds, for read and write operations since the last sampling time. Read Resp Time Shown by the all parameter. Average response time, in microseconds, for read operations since the last sampling time. Write Resp Time Shown by the all parameter. Average response time, in microseconds, for write operations since the last sampling time. Average I/O Size Shown by the all parameter. Average data size of read and write operations since the last sampling time. Average Read I/O Size Shown by the all parameter. Average data size of read operations since the last sampling time. Average Write I/O Size Shown by the all parameter. Average data size of write operations since the last sampling time. Number of Disk Errors Shown by the all parameter. Total number of disk errors detected since the last sampling time. Error types include: number of SMART events; number of timeouts accessing the disk; number of times the disk did not respond; number of attempts by the storage system to spin-up the disk; media errors generated by the disk as specified by its manufacturer; non-media errors (generated by the storage system, or by the disk and not categorized as media errors); number of bad-block reassignments. Sample Time Date and time, in the format year-month-day hour:minutes:seconds, when the data sample was taken.
