       -o [ filename ]
              Save  the  readings  in the file in binary form. Each reading is in a separate record. The default value of the filename parameter is
              the current daily data file, the /var/log/sysstat/sadd file. The -o option is exclusive of the -f option.   All  the  data  available
              from the kernel are saved in the file (in fact, sar calls its data collector sadc with the option -S ALL .  See sadc(8) manual page).

       -P { cpu [,...] | ALL }
              Report  per-processor  statistics  for the specified processor or processors.  Specifying the ALL keyword reports statistics for each
              individual processor, and globally for all processors.  Note that processor 0 is the first processor.

       -p     Pretty-print device names. Use this option in conjunction with option -d.  By default names are printed as dev m-n where m and n  are
              the  major  and  minor numbers for the device.  Use of this option displays the names of the devices as they (should) appear in /dev.

              ldavg-5
                     System load average for the past 5 minutes.

       -R     Report memory statistics. The following values are displayed:

              frmpg/s
                     Number of memory pages freed by the system per second.  A negative value represents a number of pages allocated by the system.
                     Note that a page has a size of 4 kiB or 8 kiB according to the machine architecture.

              bufpg/s
                     Number of additional memory pages used as buffers by the system per second.  A negative value means fewer pages used  as  buf‐
                     fers by the system.

              campg/s
                     Number of additional memory pages cached by the system per second.  A negative value means fewer pages in the cache.

              kbmemfree
                     Amount of free memory available in kilobytes.

              kbmemused
                     Amount of used memory in kilobytes. This does not take into account memory used by the kernel itself.

                     Amount of memory used as buffers by the kernel in kilobytes.

              kbcached
                     Amount of memory used to cache data by the kernel in kilobytes.

              kbcommit
                     Amount  of  memory  in  kilobytes needed for current workload. This is an estimate of how much RAM/swap is needed to guarantee
                     that there never is out of memory.

              %commit
                     Percentage of memory needed for current workload in relation to the total amount of memory (RAM+swap).   This  number  may  be
                     greater than 100% because the kernel usually overcommits memory.

              kbactive
                     Amount of active memory in kilobytes (memory that has been used more recently and usually not reclaimed unless absolutely nec‐
                     essary).

              kbinact
                     Amount of inactive memory in kilobytes (memory which has been less recently used. It is more  eligible  to  be  reclaimed  for
                     other purposes).

              kbdirty
                     Amount of memory in kilobytes waiting to get written back to the disk.

              %swpused
                     Percentage of used swap space.

              kbswpcad
                     Amount  of cached swap memory in kilobytes.  This is memory that once was swapped out, is swapped back in but still also is in
                     the swap area (if memory is needed it doesn't need to be swapped out again because it is already in the swap area. This  saves
                     I/O).

              %swpcad
                     Percentage of cached swap memory in relation to the amount of used swap space.

       -s [ hh:mm:ss ]
              Set  the  starting time of the data, causing the sar command to extract records time-tagged at, or following, the time specified. The
              default starting time is 08:00:00.  Hours must be given in 24-hour format. This option can be used only when data  are  read  from  a
              file (option -f ).

       -t     When reading data from a daily data file, indicate that sar should display the timestamps in the original local time of the data file
              creator. Without this option, the sar command displays the timestamps in the user's locale time.

       -u [ ALL ]

                     spent servicing hardware and software interrupts.

              %sys
                     Percentage of CPU utilization that occurred while executing at the system level  (kernel).  Note  that  this  field  does  NOT
                     include time spent servicing hardware or software interrupts.

              %iowait
                     Percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.

              %steal
                     Percentage  of  time  spent  in involuntary wait by the virtual CPU or CPUs while the hypervisor was servicing another virtual
                     processor.

              %irq
                     Percentage of time spent by the CPU or CPUs to service hardware interrupts.

              %soft
                     Percentage of time spent by the CPU or CPUs to service software interrupts.

                     Percentage of time spent by the CPU or CPUs to run a virtual processor.

              %gnice
                     Percentage of time spent by the CPU or CPUs to run a niced guest.

              %idle
                     Percentage of time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request.

              Note: On SMP machines a processor that does not have any activity at all (0.00 for every field) is a disabled (offline) processor.

              pswpin/s
                     Total number of swap pages the system brought in per second.

              pswpout/s
                     Total number of swap pages the system brought out per second.

       -w     Report task creation and system switching activity.

              proc/s
                     Total number of tasks created per second.

              cswch/s
                     Total number of context switches per second.

       -y     Report TTY devices activity. The following values are displayed:

              rcvin/s
                     Number of receive interrupts per second for current serial line. Serial line number is given in the TTY column.

              xmtin/s
                     Number of transmit interrupts per second for current serial line.

              framerr/s
                     Number of frame errors per second for current serial line.

              prtyerr/s
                     Number of parity errors per second for current serial line.

              brk/s
                     Number of breaks per second for current serial line.

              ovrun/s
                     Number of overrun errors per second for current serial line.


ENVIRONMENT
       The sar command takes into account the following environment variables:


       S_TIME_FORMAT
              If this variable exists and its value is ISO then the current locale will be ignored when printing the date  in  the  report  header.
              The sar command will use the ISO 8601 format (YYYY-MM-DD) instead.


       S_TIME_DEF_TIME
              If  this  variable  exists and its value is UTC then sar will save its data in UTC time (data will still be displayed in local time).
              sar will also use UTC time instead of local time to determine the current daily data file located in the /var/log/sysstat  directory.
              This variable may be useful for servers with users located across several timezones.

EXAMPLES
       sar -u 2 5
              Report CPU utilization for each 2 seconds. 5 lines are displayed.

       sar -I 14 -o int14.file 2 10
              Report statistics on IRQ 14 for each 2 seconds. 10 lines are displayed.  Data are stored in a file called int14.file.

       sar -r -n DEV -f /var/log/sysstat/sa16
              Display memory and network statistics saved in daily data file 'sa16'.

       sar -A
              Display all the statistics saved in current daily data file.

BUGS
       /proc filesystem must be mounted for the sar command to work.

       All  the statistics are not necessarily available, depending on the kernel version used.  sar assumes that you are using at least a 2.6 ker‐ nel.

FILES
       /var/log/sysstat/sadd
              Indicate the daily data file, where the dd parameter is a number representing the day of the month.

       /proc contains various files with system statistics.
