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 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 syntax:

              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 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 following syntax:

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

              and  open  the  resulting  SVG  file in your favorite web browser.  Output can be controlled 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 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.

       -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 customize 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 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 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.  Specifying 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 kernel, 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, 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  variable  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 triplets) 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, hostname...)

              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.
