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 | -l | -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 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 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 saYYYYMMDD, 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  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  se-
       lects 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 syntax:

              sadf -c old_datafile > new_datafile

              Conversion can be controlled using option -O (see below).

       -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  in-
              terval  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  displayed  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. 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 fol-
              lowing syntax:

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

              and open the resulting SVG file in your favorite web browser.  Output can  be  con-
              trolled using option -O (see below).

       -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  horizon-
              tally 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.

       -l     Export the contents of the data file to a PCP (Performance Co-Pilot) archive.   The
              name of the archive can be specified using the keyword pcparchive= with option -O.

       -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.

              bwcol  Use a black and white palette to draw the graphs.

              customcol
                     Use a customizable color palette instead of the  default  one  to  draw  the
                     graphs.  See environment variable S_COLORS_PALETTE below to know how to cus-
                     tomize that palette.

              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 window 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  output,  consisting  of
                     links pointing at the first graph of each activity.

              skipempty
                     Do not display views where all graphs have only zero values.

              The  following  option  may  be  used when converting an old system activity binary
              datafile to current up-to-date format:

              hz=value
                     Specify the number of ticks  per  second  for  the  machine  where  the  old
                     datafile has been created.

              The following option may be used when data are exported to a PCP archive:

              pcparchive=name
                     Specify the name of the PCP archive to create.

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

              debug  Display additional information, mainly useful for debugging purpose.

       -P { cpu_list | ALL }
              Tell sadf that processor dependent statistics are to be reported only for the spec-
              ified 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.  Specifying  the  ALL
              keyword reports statistics for each individual processor, and globally for all pro-
              cessors.

       -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.

       -r     Print  the  raw contents of the data file. With this format, the values for all the
              counters are displayed as read from the kernel, which means e.g., that  no  average
              values are calculated over the elapsed time interval.  Output can be controlled us-
              ing option -O (see above).

       -s [ hh:mm[:ss] ]
              Set the starting time of the data, 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 variables:

       S_COLORS_PALETTE
              Specify the colors used by sadf -g to render the SVG output. This environment vari-
              able  is  taken  into  account only when the custom color palette has been selected
              with the option customcol (see option -O).  Its value is a colon-separated list  of
              capabilities  associated  with six-digit, three-byte hexadecimal numbers (hex trip-
              lets) representing colors that defaults to

              0=000000:1=1a1aff:2=1affb2:3=b21aff:
              4=1ab2ff:5=ff1a1a:6=ffb31a:7=b2ff1a:
              8=efefef:9=000000:A=1a1aff:B=1affb2:
              C=b21aff:D=1ab2ff:E=ff1a1a:F=ffb31a:
              G=bebebe:H=000000:I=000000:K=ffffff:
              L=000000:T=000000:W=000000:X=000000

              Capabilities consisting of an hexadecimal digit (0 through F) are used  to  specify
              the first sixteen colors in the palette (these colors are used to draw the graphs),
              e.g., 3=ffffff would indicate  that  the  third  color  in  the  palette  is  white
              (0xffffff).
              Other capabilities are:

              G=     Specify the color used to draw the grid lines.

              H=     Specify the color used to display the report header.

              I=     Specify  the color used to display additional information (e.g., date, host-
                     name...)

              K=     Specify the color used for the graphs background.

              L=     Specify the default color (which is for example used to display the table of
                     contents).

              T=     Specify the color used to display the graphs title.

              W=     Specify the color used to display warning and error messages.

              X=     Specify the color used to draw the axes and display the graduations.

       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.
