NAME

mfscsstatsdump - dump usage data from chunkserver stats file in csv or png format

SYNOPSIS

mfscsstatsdump -f fields [-i stats_file] [-r range][-s separator] [-p png_filename [-x chart_width] [-y chart_height]] [-hHd]

DESCRIPTION

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)

OPTIONS

-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

datallopw: Low level writes (data)
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
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)

OUTPUT

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.
