How to detect process causing system load

Whenever someone copies a data Our system get very slow.

Load average of system starts increasing.

How would i find which process is causing the same.

I have tried following top 10 CPU utilizing process command but it didn't help much.

Code:

ps -auxf | sort -nr -k 3 | head -10

My distribution detail.

Code:

# lsb_release -a

LSB Version:    :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch

Distributor ID: EnterpriseEnterpriseServer

Description:    Enterprise Linux Enterprise Linux Server release 5.2 (Carthage)

Release:        5.2

Codename:      Carthage

The problem is the copy itself.
You could give a nice option to the copy command, or use
ionice

Kind regards

Yes but how would i determine it (Assume that copy is triggered by some other user and i m not aware of it).

Hi,

Have a look here: Disk I/O Analysis - Determining I/O Bottlenecks

Hope this helps.

See if iotop is available at that RHEL level.
