Re: measureware extract utility v/s sar,vmstat,iostat
It all depents on haw mutch $ you want to, or can spent and who wants the information.. explane sar output to a manager or draw a graph with maesureware.
Measureware v/s Sar, it all depents on the number off times samples are collected and the interval. I was told that measureware is more trust able but they both do snap shots from the kernel so i am not sure.
hope this will help a bit.

Re: measureware extract utility v/s sar,vmstat,iostat
measureware gathers its information through daemons, whereas sar and the like take samples.
Depends on how detailed you want to get.
You will probably be able to write scripts with sar and vmstat more easily, but some experience with measureware and you can do much more...
Enjoy your scripting.

Re: measureware extract utility v/s sar,vmstat,iostat
Each has its place. Measureware is generally used
for collecting performance data and looking at it for
an analysis point of view.
Sar, vmstat -> we use for
a quick and immediate use.
To see the cpu load distribution etc.
I need to add that, i run
scripts on certain options
of sar (sar -d for instance
to gather data on disk i/o.).
I would say, each tool complements one another.
measureware is the reliable
of the lot, since iirr, it
reads from the kernel registers. ( i don''t rememember the details).
What params to monitor using
extract? - make copies
of /var/opt/perf/reptall file
and comment out different key values as per your needs.
(GBL_CPU_TOTAL_UTIL etc.. they
are self-explanatory).

You can check this directory for a better understandings
/opt/perf/examples/adviser
Goodluck...

Re: measureware extract utility v/s sar,vmstat,iostat
for a quick snapshot i use
these parameters:
***
GBL_CPU_TOTAL_UTIL
GBL_MEM_UTIL
GBL_SWAP_SPACE_UTIL
GBL_MEM_PAGEOUT_RATE
GBL_NUM_USER
GBL_PRI_QUEUE
GBL_RUN_QUEUE
GBL_ACTIVE_PROC
****
and run the command
extract -xp -v -gp -r /tmp/reptall -b 01/xx/yy
This will create two
files in the current directory
for process(p) and global(g)
in a table format.
Based on the values, if there
is a problem, based on whether
it is disk,cpu,or i/o , i
enable other parameters to
get more detail.
