UNIX for Dummies Questions & Answers

Hi,
We have dual processor dell machine loaded with redhat linux 7.2. It was working fine without any problem but recently power went off so suddenly system switched off. From then onwards system is running very slow. My suspect is on processor. How to check both the processors running properly or not?

Thanks in advance for your's great help

Just do this:

less /proc/cpuinfo

It should show you all processors running and their capabilities/speed.

You may want to use top utility and see if all the processors are used..It will list CPU usage of each processor

Hi thanks a lot for your quick and usefull info but In top command I am not able to see second processor info. Below is the out put of top command. Two processors info available in /proc/cpuinfo file. Which is the second processor info in below top command output?

Your top display indicates a single processor. With dual processors, that cpu states line becomes two lines. And that "1 running" will often be "2 running".

What is your 'uname -a' output. When your system rebooted did it start with an smp kernel?

Here is the uname -a output:

2.4.7-10smp #1 SMP Thu Sep 6 17:09:31 EDT 2001 i686 unknown

Also copied /proc/cpuinfo:

Thanks and please let me know if there is any place i can check what is happening with the other processor?
