NAME
sysstat - report filer performance statistics
SYNOPSIS
sysstat [ interval ]
DESCRIPTION
sysstat reports filer performance statistics such as the current CPU utilization,
the amount of network I/O, the amount of disk I/O, and the amount of tape I/O.
By default, sysstat prints a new line of statistics every 15 seconds. The interval
argument overrides the default causing sysstat to report once every interval sec-
onds. Use control-C to stop sysstat.
