Add a new tool named chpstat that can be used to view channel-path
statistics such as utilization and I/O throughput, and to query and
control the status of the channel-path statistics function.
Note: Channel-path statistics are only available on systems running in
an LPAR or DPM partition.
When run without further options, data for all channel-paths is
displayed repeatedly with a 5 second delay in table format.
Example output:
CHANNEL-PATH UTILIZATION(%) READ(B/s) WRITE(B/s)
