disk3 − SCSI and NIO FL disks

sdisk − SCSI disks;

%busy Portion of time device was busy servicing a request;

avque Average number of requests outstanding for the device;

r+w/s Number of data transfers per second (read and writes) from and to the dev-

ice;

blks/s Number of bytes transferred (in 512-byte units) from and to the device;

avwait Average time (in milliseconds) that transfer requests waited idly on queue

for the device;

avserv Average time (in milliseconds) to service each transfer request (includes

seek, rotational latency, and data transfer times) for the device.

-y Report tty device activity:

rawch/s Raw input characters per second;

canch/s Input characters per second processed by canon();

outch/s Output characters per second;

rcvin/s Receive incoming character interrupts per second;

xmtin/s Transmit outgoing character interrupts per second;

mdmin/s Modem interrupt rate (not supported; always 0).

-c Report system calls:

scall/s Number of system calls of all types per second;

sread/s Number of read() and/or readv() system calls per second;

swrit/s Number of write() and/or writev() system calls per second;

fork/s Number of fork() and/or vfork() system calls per second;

exec/s Number of exec() system calls per second;

rchar/s Number of characters transferred by read system calls block devices only)

per second;

wchar/s Number of characters transferred by write system calls (block devices only)

per second.

-w Report system swapping and switching activity:

swpin/s Number of process swapins per second;

swpot/s Number of process swapouts per second;

bswin/s Number of 512-byte units transferred for swapins per second;

bswot/s Number of 512-byte units transferred for swapouts per second;

pswch/s Number of process context switches per second.

-a Report use of ﬁle access system routines:

iget/s Number of ﬁle system iget() calls per second;

namei/s Number of ﬁle system lookuppn() (pathname translation) calls per

second;

dirblk/s Number of ﬁle system blocks read per second doing directory lookup.

-q Report average queue length while occupied, and percent of time occupied. On a multi-

processor machine, if the -M option is used together with the -q option, the per-CPU run

queue as well as the average run queue of all the active processors are reported. If the -M

option is not used, only the average run queue information of all the active processors is

reported. In a multi-processor pset conﬁgured system if the -M option is used with the option

-P then pset column will will be displayed before cpu column:
