sadf


SYNOPSIS
       sadf  [ -d | -j | -p | -x ] [ -C ] [ -H ] [ -h ] [ -T ] [ -t ] [ -V ] [
       -P { cpu [,...] | ALL } ] [ -s [ hh:mm:ss ] ] [ -e [ hh:mm:ss ] ] [  --
       sar_options ] [ interval [ count ] ] [ datafile ]

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 file, the  /var/log/sysstat/sadd
       file, where the dd parameter indicates the current day.

       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.

       -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
              data  fields  as  specified by sar_options command line options.
              Note that timestamp output can be controlled by options  -T  and
              -t.

       -e [ hh:mm:ss ]
              Set  the  ending  time  of  the report, given in local time. The
              default ending time is 18:00:00. Hours must be given in  24-hour
              format.

       -H     Display  only  the header of the report (when applicable). If no
              format has been specified, then the header of the data  file  is
              displayed.

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

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

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

       -V     Print version number then exit.

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

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.

EXAMPLES
       sadf -d /var/log/sysstat/sa21 -- -r -n DEV
              Extract memory, swap space and network  statistics  from  system
              activity  file  'sa21', and display them in a format that can be
              ingested by a database.

       sadf -p -P 1
              Extract CPU statistics for processor 1  (the  second  processor)
              from  current daily data file, and display them in a format that
              can easily be handled by a pattern processing command.


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