I need to collect data about disk utilization for selected disks. I can use glance-plus monitoring tool to display the current data in percents (it looks similar to top), but I need to collect these values into a file so that I can create graphs from it.Unfortunately this isn't possible in glance so I wanted to create some own script for this purpose. I managed to create a script which collects number of blocks read / write per second, but I don't know how could I easily convert this to percents because I don't really know what the maximal utilization could be. The script is bellow:#!/bin/shlist=`iostat 10 2 | grep -v ' 0' | grep -v 'device' | grep -vE '^ *$' | sed 's/^........ *//' | sed 's/ .*//'`value=0for rt in `echo $list`dovalue=`expr $rt + $value`doneecho `expr $value / 10`is there any easier way to do this on hp-ux preferably using some free / default tools
how can I retrieve disk IO utilization in percents on HP-UX

Note that glance can be scripted:  # cat /opt/perf/examples/adviser/disk_sar  #The following glance adviser disk loop shows disk activity comparable  #to sar -d data.  #Note that values will differ between sar and glance because of differing  #data sources, calculation methods, and collection intervals.headersprinted = 0# For each disk, if there was activity, print a summary:disk loop {  if BYDSK_PHYS_IO_RATE > 0 then {    # print headers if this is the first active disk found this interval:    if headersprinted == 0 then {      print --------    device          %util   queue   r+w/s    KB/s    msecs-avserv      headersprinted = 1    }    print GBL_STATTIME,    ,BYDSK_DEVNAME|15, BYDSK_UTIL|7|2,          BYDSK_REQUEST_QUEUE|8|2, BYDSK_PHYS_IO_RATE|8|0,          BYDSK_PHYS_BYTE_RATE|8|0, BYDSK_AVG_SERVICE_TIME|16|2  }}if headersprinted == 0 then  print GBL_STATTIME,    (no disk activity this interval)To use that script : glance -aos /opt/perf/examples/adviser/disk_sar  -j 5Here BYDSK_UTIL is the % of time the disk is busy during the collection interval.Read /opt/perf/paperdocs/gp/C/gp-metrics.txt and /opt/perf/paperdocs/ovpa/C/methp.txt to see the available metrics.If you prefere other tools. You can use sar (by default on hp-ux)use egrep -f fiters to filter on your diskfor instance :(the awk is to have a time stamp for each disks) sar -d 5 10 | awk '/^[0-9]/ {t=$1} {sub(^........,t,$0); print }' | egrep -f myfilter11:56:15   device   %busy   avque   r+w/s  blks/s  avwait  avserv11:57:17 disk1680   23.76    0.50     200    3200    0.00    1.1911:57:17 disk1689    0.99    0.50       1     507    0.00    5.4511:57:17 disk1694   41.58    0.50     237    3786    0.00    1.7511:57:17 disk1696    0.00    0.50       1      16    0.00    2.0711:57:17 disk1707    0.99    0.50       1      16    0.00    5.8211:57:17 disk1709    4.95    0.50       2    2044    0.00   24.1011:57:17 disk1712    3.96    0.50       2    1980    0.00   23.69...With myfilter containing the disks you want to watch.  # cat  myfilterdisk1680 disk1689 ...add a blank character    after each disks names, otherwise disk1 would match disk10
