DESCRIPTION
       The sadf command is used for displaying the contents of data files cre-
       ated  by the sar(1) command. But unlike sar, sadf can write its data in
       many different formats (CSV, XML, etc.)  The default format is one that
       can  easily  be  handled  by  pattern processing commands like awk (see
       option -p).

       The sadf command extracts and writes to standard output  records  saved
       in  the datafile file. This file must have been created by a version of
       sar which is compatible with that of sadf.   If  datafile  is  omitted,
       sadf  uses  the  standard  system activity daily data file.  It is also
       possible to enter -1, -2 etc. as an argument to sadf to display data of
       that  days  ago.   For  example,  -1  will point at the standard system
       activity file of yesterday.

       The standard system activity daily data file is named saDD or  saYYYYM-
       MDD,  where  YYYY stands for the current year, MM for the current month
       and DD for the current day.  sadf will look for the most recent of saDD
       and   saYYYYMMDD,  and  use  it.  By  default  it  is  located  in  the
       /var/log/sysstat directory. Yet it is possible to specify an  alternate
       location  for  it: If datafile is a directory (instead of a plain file)
       then it will be considered as the directory where the  standard  system
       activity daily data file is located.

       The interval and count parameters are used to tell sadf to select count
       records at interval seconds apart. If the count parameter is  not  set,
       then all the records saved in the data file will be displayed.

       All  the  activity  flags  of sar may be entered on the command line to
       indicate which activities are to be reported. Before  specifying  them,
       put  a  pair of dashes (--) on the command line in order not to confuse
       the flags with those of sadf.  Not specifying any  flags  selects  only
       CPU activity.

OPTIONS
       -C     Tell sadf to display comments present in file.

       -c     Convert  an  old  system activity binary datafile (version 9.1.6
              and later) to current up-to-date format. Use the following  syn-
              tax:

              sadf -c old_datafile > new_datafile

       -d     Print  the contents of the data file in a format that can easily
              be ingested by a relational database system. The output consists
              of  fields  separated  by  a semicolon. Each record contains the
              hostname of the host where the file was  created,  the  interval
              value  (or -1 if not applicable), the timestamp in a form easily
              acceptable by most databases, and additional semicolon separated

       -h     When  used in conjunction with option -d, all activities will be
              displayed horizontally on a single line.

       -j     Print the contents of the data file in JSON  (JavaScript  Object
              Notation) format. Timestamps can be controlled by options -T and
              -t.

       -P { cpu [,...] | ALL }
              Tell sadf that processor dependent statistics are to be reported
              only  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     Print the contents of the data file in a format that can  easily
              be  handled by pattern processing commands like awk.  The output
              consists of fields separated by a tab. Each record contains  the
              hostname  of  the  host where the file was created, the interval
              value (or -1 if not applicable), the timestamp, the device  name
              (or  -  if  not applicable), the field name and its value.  Note
              that timestamp output can be controlled by options  -T,  -t  and
              -U.

       -s [ hh:mm[:ss] ]
              Set the starting time of the data (given in local time), causing
              the sadf command to extract records time-tagged at,  or  follow-
              ing,  the time specified. The default starting time is 08:00:00.
              Hours must be given in 24-hour format.

       -T     Display timestamp in local time instead of UTC (Coordinated Uni-
              versal Time).

       -t     Display  timestamp  in  the original local time of the data file
              creator instead of UTC (Coordinated Universal Time).

       -U     Display timestamp (UTC - Coordinated Universal Time) in  seconds
              from the epoch.

       -V     Print version number then exit.

       -x     Print  the  contents of the data file in XML format.  Timestamps
              can be controlled by options -T and -t.  The  corresponding  DTD
              (Document  Type  Definition)  and XML Schema are included in the
              sysstat source package. They are also available at http://pages-
              perso-orange.fr/sebastien.godard/download.html

ENVIRONMENT
       The sadf command takes into account the following environment variable:

       S_TIME_DEF_TIME
              If  this variable exists and its value is UTC then sadf will use
              UTC time instead of local time to determine  the  current  daily
              data file located in the /var/log/sysstat directory.

FILES
       /var/log/sysstat/saDD
       /var/log/sysstat/saYYYYMMDD
              The  standard system activity daily data files and their default
              location.  YYYY stands for the current year, MM for the  current
              month and DD for the current day.
