$reads_completed_successfully,# Since boot
$reads_merged,# How often adjacent reads are merged before being passed to the IO driver
$sectors_read,# This is the total number of sectors read successfully.
$time_spent_reading,# This is the total number of milliseconds spent by all reads
$writes_completed,# Since boot
$writes_merged,# How often adjacent writes are merged before being passed to the IO driver
$sectors_written,# This is the total number of sectors written successfully
$time_spent_writing,# This is the total number of milliseconds spent by all writes
$ios_currently_in_progress,# Number of I/Os currently in progress. - This is what we care about the most
$time_spent_doing_ios,# This field increases so long as above is non-zero. counts jiffies when at least one request was started or completed. If request runs more than 2 jiffies then some I/O time might be not accounted in case of concurrent requests
$weighted_time_spent_doing_ios,# Weighted number of milliseconds spent doing I/Os. This field is incremented at each I/O start, I/O completion, I/O merge, or read of these stats by the number of I/Os in progress times the number of milliseconds spent doing I/O since the last update of this field. This can provide an easy measure of both I/O completion time and the backlog that may be accumulating.
$discards_completed_successfully,# This is the total number of discards completed successfully.
$discards_merged,# How often adjacent discards are merged before being passed to the IO driver
$sectors_discarded,# This is the total number of sectors discarded successfully
$time_spent_discarding,# This is the total number of milliseconds spent by all discards
$flush_requests_completed_successfully,# This is the total number of flush requests completed successfully.
$time_spent_flushing# This is the total number of milliseconds spent by all flush requests.
