The output column descriptions are:
sysstat 1
Displays the default output every second, requires
control-C to terminate.
sysstat -s 1
Displays the default output every second, upon
control-C termination print out the summary
statistics.
sysstat -c 10
Displays the default output every 15 seconds,
stopping after the 10th iteration.
sysstat -c 10 -s -u 2
sysstat -u -c 10 -s 2
Displays the utilization output format, every 2
seconds, stopping after the 10th iteration, upon
completion print out the summary statistics.
sysstat -x -s 5
Displays the extended (full) output, every 5
seconds, upon control-C termination print out the
summary statistics.
The statistics displayed by the sysstat command are cumulative; a giveback operation does not zero out the statistics. That is, after giving back its partner's resources, the live node does not subtract the statistics about operations it performed on behalf of the failed node in takeover mode.
