NAME

       sadf - Display data collected by sar in multiple formats.

SYNOPSIS

       sadf  [ -d | -D | -H | -p | -x ] [ -C ] [ -h ] [ -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
       created 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     This  option  is  equivalent to option -d below, except that the
              timestamp  is  always  expressed  in  seconds  since  the  epoch
              (00:00:00 UTC 01/01/1970).

       -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  the  timestamp  is  displayed  in  UTC  (Coordinated
              Universal  Time)  unless option -t is used. In this latter case,
              the timestamp is displayed in local time.

       -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.  This option is ignored when option -x is used.

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

       -H     Display the header of the data file.

       -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 (UTC value -
              Coordinated Universal Time)  in  seconds  from  the  epoch,  the
              device  name  (or  -  if not applicable), the field name and its
              value.

       -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
              following, the time specified.  The  default  starting  time  is
              08:00:00.  Hours must be given in 24-hour format. This option is
              ignored when option -x is used.

       -t     When this option is used together with options  -d  or  -x,  the
              timestamp is displayed in local time instead of UTC (Coordinated
              Universal Time).  This option is ignored when options -p  or  -D
              are used.

       -V     Print version number then exit.

       -x     Print  the  contents of the data file in XML format.  Timestamps
              are displayed in UTC (Coordinated Universal Time) unless  option
              -t  is used, in which case they are displayed in local time. The
              corresponding DTD (Document Type Definition) and XML Schema  are
              included  in the sysstat source package. They are also available
              at http://pagesperso-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.

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.
