Re: Average memory utilization

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

Regards
Sanjeev

Re: Average memory utilization

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

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

Re: Average memory utilization

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.

Re: Average memory utilization

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,

Regards!

Re: Average memory utilization

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.

Hi Vishu,

>>>>WARNING: scopeux is not active (MWA data collector)
>>>>WARNING: alarmgen is not active (alarm generator)
>>>>WARNING: agdbserver is not active (alarm database server)

Try restarting mwa:
mwa stop ; mwa start

If its not solving the problem:
Then first copy all log files to different location and empty the logs.

ll /var/opt/perf/datafiles/log*

Try restarting mwa again:

Let me know hows the extract output.

Good Luck!!
