NAME
ioping - simple disk I/O latency monitoring tool
SYNOPSYS
ioping [-LCDRq] [-c count] [-w deadline] [-p period] [-i interval] [-s size] [-S wsize] [-o offset] device|file|directory
ioping -h | -v
DESCRIPTION
This tool lets you monitor I/O latency in real time.
OPTIONS
-c count
Stop after count requests.
-w deadline
Stop after deadline time passed.
-p period
Print raw statistics for every period requests.
-i interval
Set time between requests to interval (1s).
-s size
Request size (4k).
-S size
Working set size (1m).
-o offset
Offset in input file.
-L Use sequential operations rather than random. This also sets request size to 256k (as in -s 256k).
-C Use cached I/O.
-D Use direct I/O.
-R Disk seek rate test (same as -q -i 0 -w 3 -S 64m).
-q Suppress human-readable output.
-h Display help message and exit.
-v Display version and exit.
Argument suffixes
For options that expect time argument (-i and -w), default is seconds, unless you specify one of the following suffixes (case-insensitive):
us, usec
microseconds
ms, msec
milliseconds
s, sec seconds
m, min minutes
h, hour
hours
For options that expect "size" argument (-s, -S and -o), default is bytes, unless you specify one of the following suffixes (case-insensi-
tive):
s disk sectors (a sector is always 512).
k, kb kilobytes
p memory pages (a page is always 4K).
m, mb megabytes
g, gb gigabytes
t, tb terabytes
For options that expect "number" argument (-p and -c) you can optionally specify one of the following suffixes (case-insensitive):
k kilo (thousands, 1 000)
m mega (millions, 1 000 000)
g giga (billions, 1 000 000 000)
t tera (trillions, 1 000 000 000 000)
EXIT STATUS
Returns 0 upon success. The following error codes are defined:
1 Invalid usage (error in arguments).
2 Error during preparation stage.
3 Error during runtime.
EXAMPLES
ioping .
Show disk I/O latency using the default values and the current directory, until interrupted.
ioping -c 10 -s 1M /tmp
Measure latency on /tmp using 10 requests of 1 megabyte each.
ioping -R /dev/sda
Measure disk seek rate.
ioping -RL /dev/sda
Measure disk sequential speed.
