sadf


SYNOPSIS

       sadf [ -C ] [ -d | -j | -p | -x ] [ -H ] [ -h ] [ -T | -t | -U ] [ -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/sa/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,  -t
              and -U.

       -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
              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/sa directory.


EXAMPLES

       sadf -d /var/log/sa/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.
