Performance Testing

[Suriya Prakash]

Hi,

I have a HP Integrity rx2660 server and EVA 4400 storage. I want to check the performance of the server like ram usage, processor usage and free hard disk space. and i also want to check the EVA performance, space allocated to EVA, space used and space free.

Pls guide me to check this.

Regards,
Suriya.

If you have Glance installed on your server, you can get all these details. Else use native commands like top,sar, vmstat, iostat etc..

If you have access to Command View EVA, you can get the details of your EVA storage..

Thanks

Hi,

check whether glance installed.

swlist |grep -i glance

If installed, execute the below command to check your memory, cpu etc usage.

glance

Otherwise, you can use the command top

Glance is not installed on my server.
Tell me any other way to check.

[Paul Procter]

type
# sar -a

that should provide some information.

type
# man sar

To explain what the parameters mean.

Hi,

My question is simple, how to check the usage of processor and RAM. for whick process it takes more ram and processor. like we check in task manager of windows machine.

Thanks.

Hi,
You can use glance to monitor the performance and if you see more memory and CPU utilisation then you can use following commands to check the high resource utilizing processes.

to check high memory processes

UNIX95= ps -ef -o "vsz,pid,user,pcpu,args"|sort -rn -k1 |head -30

for high CPU

UNIX95= ps -ef -o pcpu="CPU %" -o ruser=USER -o pid,args|sort -rk1|head -30

if you're used to the task manager, then the "top" command is your choice
