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 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, 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 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 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 (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 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 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.
