dstat - versatile tool for generating system resource statistics
OPTIONS
-c, --cpu
enable cpu stats (system, user, idle, wait, hardware interrupt, software
interrupt)
-C 0,3,total
include cpu0, cpu3 and total
-d, --disk
enable disk stats (read, write)
-D total,hda
include hda and total
-g, --page
enable page stats (page in, page out)
-i, --int
enable interrupt stats
-I 5,10
include interrupt 5 and 10
-l, --load
enable load average stats (1 min, 5 mins, 15mins)
-m, --mem
enable memory stats (used, buffers, cache, free)
-n, --net
enable network stats (receive, send)
-N eth1,total
include eth1 and total
-p, --proc
enable process stats (runnable, uninterruptible, new)
-r, --io
enable I/O request stats (read, write requests)
-s, --swap
enable swap stats (used, free)
-S swap1,total
include swap1 and total
-t, --time
enable time/date output
-T, --epoch
enable time counter (seconds since epoch)
-y, --sys
enable system stats (interrupts, context switches)
--aio enable aio stats (asynchronous I/O)
--fs enable filesystem stats (open files, inodes)
--ipc enable ipc stats (message queue, semaphores, shared memory)
--lock enable file lock stats (posix, flock, read, write)
--raw enable raw stats (raw sockets)
--socket
enable socket stats (total, tcp, udp, raw, ip-fragments)
--tcp enable tcp stats (listen, established, syn, time_wait, close)
--udp enable udp stats (listen, active)
--unix enable unix stats (datagram, stream, listen, active)
--vm enable vm stats (hard pagefaults, soft pagefaults, allocated, free)
--stat1 --stat2
enable (external) plugins by plugin name, see PLUGINS for options
Possible internal stats are
aio, cpu, cpu24, disk, disk24, disk24old, epoch, fs, int, int24, io, ipc,
load, lock, mem, net, page, page24, proc, raw, socket, swap, swapold, sys,
tcp, time, udp, unix, vm
--list list the internal and external plugin names
-a, --all
equals -cdngy (default)
-f, --full
expand -C, -D, -I, -N and -S discovery lists
-v, --vmstat
equals -pmgdsc -D total
--bw, --blackonwhite
change colors for white background terminal
--float
force float values on screen (mutual exclusive with --integer)
--integer
force integer values on screen (mutual exclusive with --float)
--nocolor
disable colors (implies --noupdate)
--noheaders
disable repetitive headers
--noupdate
disable intermediate updates when delay > 1
--output file
write CSV output to file
EXAMPLES
Using dstat to relate disk-throughput with network-usage (eth0), total CPU-usage
and system counters:
dstat -dnyc -N eth0 -C total -f 5
Checking dstat’s behaviour and the system impact of dstat:
dstat -taf --debug
Using the time plugin together with cpu, net, disk, system, load, proc and top_cpu
plugins:
dstat -tcndylp --top-cpu
this is identical to
dstat --time --cpu --net --disk --sys --load --proc --top-cpu
Using dstat to relate cpu stats with interrupts per device:
dstat -tcyif
PLUGINS
--nfs3 show NFS v3 client operations
--nfs3-ops
show extended NFS v3 client operations
--nfsd3
show NFS v3 server operations
--nfsd3-ops
show extended NFS v3 server operations
