NAME

mfsstatsdump - dump usage data from master stats file in csv or png format

SYNOPSIS

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

DESCRIPTION

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)

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/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

FIELDS

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)

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)
