Atop version 2.7.0

Various system activity reports can be generated by the command atopsar similar to the traditional UNIX sar command. The command atopsar is a symlink to the command atop and will be added automatically during the installation phase of atop.
Colors and (on request) markers are used by atopsar to highlight that the utilization of a resource is critical (red) or almost critical (cyan).

With the flag -c in the following example a report is generated about current CPU utilization of the system during 5 minutes (five times with an interval of sixty seconds):

$ atopsar -c 60 5

14:22:11  cpu %usr %nice   %sys %irq %softirq   %steal    %wait %idle     _cpu_
14:23:11  all    2     0      8    1        1        0       88     0
14:24:11  all   32     0     38    1        1        0       28     0
14:25:11 all 43 0 45 2 1 0 0 9
14:26:11 all 2 0 2 1 1 0 15 79 14:27:11 all 2 0 1 0 0 0 11 86

With the flag -A in the following example all available reports are generated, starting from 13:00 (optional flag -b) till 13:35 (optional flag -e) reading today's raw file as written by the atop command (default):

$ atopsar -A -b 13:00 -e 13:35

13:00:01  cpu %usr %nice   %sys %irq %softirq   %steal    %wait %idle     _cpu_
