[Vishu]

Hi,

please help in taking the average memory utilization of HP-UX 11.00 server for one week. As for disk and CPU usage, we can have from sar command. which command we will use for memory.

Thanks

Hi vishu

The commands sar and vmstat

For example, sample CPU utilisation every 2 seconds for 5 iterations:

sar -u 2 5

or For memory utilisation every 2 seconds for 5 iterations:

vmstat 2 5

look at the avm and free fields

Thanks Sanjeev and Michal,

But i dont have the glance installed in my server...

and if vmstat helps, then i need it for one complete week. By anyway, i can add it to cron or any other way.

Thanks

hi,

i don't like top but in some cases could be used.

maybe the top will help you.

Shalom,

the sar commands will work.

This script will give you a complete performance snapshot using sar that will meet your needs:

No cost uses sar

production code.

Glance is available on your OS CD for 60 day evaluation.

in top output, i found following line as memory


Memory: 772800K (271340K) real, 585612K (233832K) virtual, 669856K free Page# 1/15

can you please tell me in detail, what each field is showing. My server RAM is 4096MB, but i have not seen anything in GB in this output.

Plz suggest.

Hi Vishu:

On of the "best" tools for doing what you want to do is 'glance' and 'measureware'. The reason is that 'glance' is architected to "understand" the HP-UX kernel. 'top' and 'sar' are more generic UNIX tools. With 'glance'/'measureware' you can collect and graph long term metrics,

Thanks James,

but i am trying with glance too on one server and trying to extract the data for today, but it is replying with the error :-

# ./extract -xp -r /tmp/moni -g -b today 14:00 -e today 15:00 -f stdout


Unable to read record from logfile, size returned = 0
Unable to read record from logfile, size returned = 0
Memory fault(coredump)

Plz suggest.

Hello Vishu,

>>>>Unable to read record from logfile, size returned = 0
>>>>Memory fault(coredump)

Check the status of measureware daemons:
#mwa status

Check the log files in:
/var/opt/perf/datafiles/log*

if its showing zero in size; try restarting mwa:

#mwa stop ; mwa start

Let me know the outcome.

Cheers!!
