    Command:

    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
                  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-
                  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.
