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

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

SYNOPSIS
       sadf  [  -C ] [ -c | -d | -g | -j | -p | -r | -x ] [ -H ] [ -h ] [ -T |
       -t | -U ] [ -V ] [ -O opts [,...] ] [ -P { cpu_list | ALL } ]  [  -s  [
       hh:mm[:ss]  ]  ]  [  -e  [  hh:mm[:ss]  ] ] [ --dev= dev_list ] [ --fs=
       fs_list ] [ --iface= iface_list ] [ -- sar_options ] [ interval [ count
       ] ] [ datafile | -[0-9]+ ]

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 can also be used to draw graphs for the
       various activities collected by sar and display them as  SVG  (Scalable
       Vector Graphics) graphics in your web browser (see option -g).

       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 daily data  file.   It  is  also
       possible to enter -1, -2 etc. as an argument to sadf to display data of
       that days ago.  For example, -1  will  point  at  the  standard  system
       activity file of yesterday.

       The  standard system activity daily data file is named saDD or saYYYYM-
       MDD, where YYYY stands for the current year, MM for the  current  month
       and DD for the current day.  sadf will look for the most recent of saDD
       and  saYYYYMMDD,  and  use  it.  By  default  it  is  located  in   the
       /var/log/sysstat  directory. Yet it is possible to specify an alternate
       location for it: If datafile is a directory (instead of a  plain  file)
       then  it  will be considered as the directory where the standard system
       activity daily data file is located.

       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.

       -c     Convert an old system activity binary  datafile  (version  9.1.6
              and  later) to current up-to-date format. Use the following syn-
              tax:

              sadf -c old_datafile > new_datafile

       -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.

       --dev=dev_list
              Specify the block devices for which statistics are  to  be  dis-
              played  by  sadf.   dev_list is a list of comma-separated device
              names. Useful with option -d from sar.

       -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.

       --fs=fs_list
              Specify the filesystems for which statistics are to be displayed
              by  sadf.  fs_list is a list of comma-separated filesystem names
              or mountpoints. Useful with option -F from sar.

       -g     Print the contents of the data  file  in  SVG  (Scalable  Vector
              Graphics) format.  This option enables you to display some fancy
              graphs in your web browser.  Use the following syntax:

              sadf -g your_datafile [ -- sar_options ] > output.svg

              and open the resulting SVG file in your favorite web browser.

       -H     Display only the header of the report (when applicable).  If  no
              format  has  been  specified, then the header data (metadata) of
              the data file are displayed.

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

       --iface=iface_list
              Specify  the  network  interfaces for which statistics are to be
              displayed by sadf.  iface_list  is  a  list  of  comma-separated
              interface  names.  Useful  with  options -n DEV and -n EDEV from
              sar.

       -j     Print the contents of the data file in JSON  (JavaScript  Object
              Notation) format. Timestamps can be controlled by options -T and
              -t.

       -O opts [,...]
              Use the specified options to control the output  of  sadf.   The
              following  options  are  used to control SVG output displayed by
              sadf -g:

              autoscale
                     Draw all the graphs of a given view as large as  possible
                     based  on current view's scale. To do this, a factor (10,
                     100, 1000...) is used to enlarge the graph drawing.  This
                     option  may  be interesting when several graphs are drawn
                     on the same view, some with only very small  values,  and
                     others  with  high  ones,  the  latter  making the former
                     hardly visible.

              height=value
                     Set SVG canvas height to value.

              oneday
                     Display graphs data over a period of 24 hours. Note  that
                     hours are still printed in UTC by default: You should use
                     option -T to print them in local time and get a time win-
                     dow starting from midnight.

              packed
                     Group  all views from the same activity (and for the same
                     device) on the same row.

              showidle
                     Also display %idle state in graphs for CPU statistics.

              showinfo
                     Display additional information (such as the date and  the
                     host name) on each view.

              showtoc
                     Add  a table of contents at the beginning of the SVG out-
                     put, consisting of links pointing at the first  graph  of
                     each activity.

              skipempty
                     Do not display views where all graphs have only zero val-
                     ues.

              The following option is used to control raw output displayed  by
              sadf -r:

              debug
                     Display  additional information, mainly useful for debug-
                     ging purpose.

       -P { cpu_list | ALL }
              Tell sadf that processor dependent statistics are to be reported
              only  for  the specified processor or processors.  cpu_list is a
              list  of  comma-separated  values  or  range  of  values  (e.g.,
              0,2,4-7,12-).  Note that processor 0 is the first processor, and
              processor all is the global average among all processors.  Spec-
              ifying  the  ALL  keyword reports statistics for each individual
              processor, and globally for all processors.

       -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, 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.

       -r     Print  the  raw contents of the data file. With this format, the
              values for all the counters are displayed as read from the  ker-
              nel,  which  means  e.g.,  that no average values are calculated
              over the elapsed time interval.

       -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/sysstat directory.

EXAMPLES
       sadf -d /var/log/sysstat/sa21 -- -r -n DEV
              Extract memory 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.

BUGS
       SVG output (as created by option -g) is fully compliant  with  SVG  1.1
       standard.   Graphics  have  been  successfully displayed in various web
       browsers, including Firefox, Chrome and Opera.  Yet  SVG  rendering  is
       broken  on  Microsoft browsers (tested on Internet Explorer 11 and Edge
       13.1): So please don't use them.

FILES
       /var/log/sysstat/saDD
       /var/log/sysstat/saYYYYMMDD
              The standard system activity daily data files and their  default
              location.   YYYY stands for the current year, MM for the current
              month and DD for the current day.
