mfscsstatsdump(8) This is part of MooseFS mfscsstatsdump(8)

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

csrepin
Data received by replicator
csrepout
Data sent by replicator
csservin
Data received by csserv
csservout

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

repl
Replicate chunk ops
create
Create chunk ops
delete
Delete chunk ops
version

duplicate
Duplicate ops
truncate

duptrunc
Duptrunc (duplicate+truncate) ops
test
Test chunk ops
load
Server load
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)

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.
