Hi ,
Thanks for your reply techy, I am not experienced in monitoring stuffs, ill try to post your required details while causing today.

Actually that was an impact when user are high during business hours.
It was normal now. OBIEE app is running in this server.
I checked the Process, disk IO, network traffic at that time. I suspect only the nqsserve (BIP owner ) process consuming more usage.
I only have this output which i executed yesterday,
