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 exclusive with -h, -H and -d options.

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