How do I measure the average utilization

How do I measure the average utilization of the HP box. I need to measure the utilization of the processors, disks, and NIC's. Any suggestion other then to purchase Glance. THX, Otto

Hi,

Measureware (Glance+ Pak) has been a very good product of HP that many customers have been following for their performance and capacity management solutions. There are two threads today itself that discussed about this and should help you determine if it is worth having it. You can get a trial version from your Application CDs to try the product.

Once you have it installed, it will start collecting information automatically. You can generate reports using measureware's "extract" command or Perfview's "pv" graphical interface. Look at man pages for more details.

Also look at the following thread

I have also used BMC's BEST/1 which is as good as HP's Measureware. But it concentrates more on CPU metrics.

Use sar, do a man on sar and you'll see how to check cpu utilization, disk utilization etc..and have a look on vmstat if you want to know about memory utilizations.

Thanks

The best way to do this, of course is to use Glance. But however, the other alternative, which is free, is to use Top command. Top lets you see your average utilisation of the CPU, memory and load usages.

Hi Otto,
For monitoring the system utilization, you can use sar on regular interval the put the output to a file.

sar -o sar_op 6 10

and later you can check the file for details.
You can run this through cron for collecting data.

Also you can use the following commands.

processor:

w -u
sar -Mu 2 3 ( M for Multiprocessor)
top

disks:
iostat
sar -d 2 3

NIC's
netstat -s

Memory
vmstat -n
swapinfo -tam
sar -b
sar -w.

Happy Tuning
Srini.
