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 mfschunkserver.cfg(5)
-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; default:320) -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.
