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
- 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)
- masterin
- Data received from master
- masterout
- Data sent to master
- csrepin
- Data received by replicator
- csrepout
- Data sent by replicator
- csservin

- csservout
- Data sent by csserv
- bwin
- Data bandwidth in (in csv sum of csrepin and csservin, in png shows both
in different colors)
- bwout
- Data bandwidth out (in csv sum of csrepout and csservout, in png shows
both in different colors)
- hdrbytesr

- hddread
- HDD read (in csv sum of hdrbytesr and databytesr, in png shows both in
different colors)
- hddwrite
- HDD write (in csv sum of hdrbytesw and databytesw, in png shows both in
different colors)
- hddopsr
- HDD low level read (in csv sum of hdrllopr and datallopr, in png shows
both in different colors)
- hddopsw
- HDD low level write (in csv sum of hdrllopw and datallopw, in png shows
both in different colors)
- hlopr
- High level reads
- hlopw
- High level writes
- rtime
- Read time
- wtime
- Write time
- repl
- Replicate chunk ops
- create
- Create chunk ops
- delete
- Delete chunk ops
- version
- Set version ops
- duplicate
- Duplicate ops
- truncate
- Truncate ops
- duptrunc
- Duptrunc (duplicate+truncate) ops
- test
- Test chunk ops
- load
- Server load
- 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)
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.
