HP-UX Reference (11i v3 07/02) - 1M System Administration Commands N-Z (vol 4)

s
sar(1M) sar(1M)
device Logical name of the device and its corresponding instance. Devices are
categorized into the following device types:
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.
r/s Number of reads per second from the device. This information is available
only when used with the -R option.
w/s Number of writes per second to the device. This information is available
only when used with the -R option.
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.
-f Uses file as the data source for sar. Default is the current daily data file
/var/adm/sa/sadd
.
-H Report activity for each HBA device. One line is printed for each HBA device that had activity
during the last interval. If no devices were active, a blank line is printed. Each line contains
the following data:
ctlr Logical name of the HBA device and its corresponding instance.
%util Portion of time device was busy servicing a request.
t-put Number of bytes transferred (in MBs) from and to the device.
IO/s Number of data transfers per second (read and writes) from and to the dev-
ice.
r/s Number of reads per second from the device.
w/s Number of writes per second to the device.
read Number of bytes read (in MBs) from the device.
write Number of bytes written (in MBs) to the device.
avque Average number of requests outstanding for 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 for the dev-
ice.
-L Report activity for each active lunpath. One line is printed for each lunpath that had activity
during the last interval. If no lunpath were active, a blank line is printed. The lunpaths are
not displayed in any specific order and it is not guaranteed that the current order will be main-
tained in future releases. Each line contains the following data:
lunpath symbolic name of the lunpath of the form: diskm_lunpathn, where m and
n are the instance numbers of LUN and lunpath respectively. These
instance numbers are displayed by ioscan using option -N, for the LUN
and lunpath entries. For more information on LUN and lunpath hardware
path, refer to intro(7).
%busy Portion of time lunpath was busy servicing a request.
avque Average number of requests outstanding for the lunpath.
r/s Number of reads per second from the lunpath.
