mfsstatsdump - dump usage data from master stats file in csv or png format mfsstatsdump -f fields [-i stats_file] [-r range] [-s separator] [-p png_filename [-x chart_width] [-y chart_height]] [-hHd] 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)

-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

14 ucpu User cpu usage

scpu System cpu usage

cpu Total cpu usage (in csv sum of scpu and ucpu, in png shows both in different colors)

delete Number of chunk deletions

replicate Number of chunk replications

statfs Number of statfs operations

getattr Number of getattr operations

setattr Number of setattr operations

lookup Number of lookup operations

mkdir Number of mkdir operations

rmdir Number of rmdir operations

symlink Number of symlink operations

readlink Number of readlink operations

mknod Number of mknod operations

unlink Number of unlink operations

rename Number of rename operations

link Number of link operations

readdir Number of readdir operations

open Number of open operations

read Number of read operations

write Number of write operations

prcvd Received packets

psent Sent packets

brcvd Received bytes

bsent Sent bytes

memoryrss Resident memory usage

memoryvirt Virtual memory usage

mem Total memory usage (in csv is the same as memoryvirt, in png shows both memoryrss and memoryvirt using two colors)

usedspace Used raw disk space

totalspace Total raw disk space

space Total raw disk space (in csv the same as totalspace, in png shows both usedspace and totalspace using two colors)

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.
