       mfscsstatsdump - dump usage data from chunkserver stats file in csv or png format


       mfscsstatsdump  -f  fields  [-i  stats_file] [-r range][-s separator] [-p png_filename [-x
       chart_width] [-y chart_height]] [-hHd]


       mfscsstatsdump dumps usage data from chunkserver stats file.  These are the same data sets
       that  are  used  to  make  CGI  charts.  Output  can  be either in text format (csv) or in
       graphical format (png). That means -p, -x and -y options are mutually exclusive  with  -h,
       -H and -d options.

       MooseFS   chunkserver   saves   the   stats   file   in  the  DATA_PATH  directory  -  see


       -f     field names separated by ',' (see FIELDS section); at least one field is mandatory;
              if an asterisk (*) is used, all fields are dumped

       -i     name of mfs binary stats file (default: default_data_path/csstats.mfs)

       -r     range  type:  0  - short range (minute) 1 - medium range (6 minutes) 2 - long range
              (30 minutes) 3 - very long range (day)

       -s     specify column separator (default: tabulator)

       -p     optional  PNG  filename  (field  name  will  be  added   before   .png;   YYYY   ->
              YYYY_FIELD.png, YYYY.png -> YYYY_FIELD.png)

       -x     PNG chart width (default: 1600)

       -y     PNG  chart  height  (should  be  divisible by 20 - if not then it will be adjusted;

       -h     "human-readable" numbers using base 2 prefixes (IEC 60027)

       -H     "human-readable" numbers using base 10 prefixes (SI)

       -d     show timestamps in YYYY-MM-DD HH:MM format

       Text output - text (csv) file where first column is a timestamp (or date if -d option  was
       specified),  the  following  column  are what was specified with the -f options, formatted
       according to used options (none, -s and -h or -H)

       Graphical output - one png file with a chart is created for every field specified with the
       -f  option,  according  to  the  naming  scheme  declared  with the -p option. Size may be
       adjusted with -x and -y options.
