NAME
mfsstatsdump - dump usage data from master stats file in csv or png format

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

DESCRIPTION
mfsstatsdump dumps usage data from master 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 exlusive with -h, -H and -d options.

MooseFS master server saves the stats file in the DATA_PATH directory - see mfsmaster.cfg(5)

OPTIONS

-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/stats.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
