SADF(1)                                                         Linux User's Manual                                                        SADF(1)

NAME

       sadf - Display data collected by sar in multiple formats.

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 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/sys-
       stat/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  dis-
              played.

       -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 option -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  pro-
              cessor.

       -p     Print the contents of the data file in a format that can easily be handled by pattern processing commands like awk.  The output con-
              sists 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  following,
              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 Universal 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-
              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.

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.
