interval is the number of seconds between samplings. The default is one second.
count is the number of samples to make; the default is to sample indefinitely.
The information displayed for each interval includes the number of I/Os queued (total
block and raw), minimum and maximum latency, count of I/Os, and average latency.
The statistics are organized by I/O, with only actively used sizes shown.
Latencies are in milliseconds. The minimum and maximum latency is reset every
interval. The number of I/Os queued is an instantaneous value that is taken at the
time of the sample.
NOTE:
If interval is too long, the average latency computation may be affected by 32-bit
computer wrap-around. A total of 71 minutes of I/O may be measured before
counter wrap-around. This does not necessarily equate to 71 minutes in realtime.
Dump I/O statistics in raw format
The rawstat command dumps general I/O statistics for each device in raw format.
The output is typically passed to programs or shell scripts for further processing.
Numbers are the raw counter values, not computed per sample. The syntax for the
command is:
rawstat [<interval> [<count>]] [<psddev>...]
interval is the number of seconds between samplings. The default is one second.
count is the number of samples to make; the default is to sample indefinitely.
The output consists of ASCII text delimited by carets. The fields are:
1. PSD device name
2. Sample number
3. Sampling interval
4. Number of targets
5. Current active target
6. Number of I/O sizes
7. First I/O size (power of 2)
8. Number of I/Os queued (includes raw)
9. Number of raw I/Os queued
