NAME
       sadf - Display data collected by sar in multiple formats.

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 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/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 inter-
       val 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 activi-
       ties 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 displayed  horizon-
	      tally 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 spec-
	      ified  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 pat-
	      tern 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 following, 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 Universal 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://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/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.

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