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
- 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

- prcvd
- Received packets
- psent
- Sent packets
- brcvd
- Received bytes
- bsent
- Sent bytes
- 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)

field specified with the -f option, according to the naming scheme
declared with the -p option. Size may be adjusted with -x and
