I want to find number of CPU and number NIC card in Linux server.
I have below content in /proc/cpuinfo. I have from processor 0 - 15. It means, i have 15 similar entries in that file. How many CPU we have on this server? also how do find how many NIC card on this?
Code:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 6
model name : Intel(R) Xeon(TM) CPU 3.20GHz
stepping : 8
cpu MHz : 3192.180
cache size : 8192 KB
physical id : 0
siblings : 4
core id : 0
cpu cores : 2
fpu : yes
fpu_exception : yes
cpuid level : 6
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall lm pni monitor ds_cpl est tm2 cid cx16 xtpr lahf_lm
bogomips : 6393.99

Hi..,
my dout is a solaris server is having 16 cpu's.
in tht one cpu running some error process, accupaying more space.
I wanna down tht particular CPU only with out interrupting the other 15
CPU's. how can i do this. is there any command for this ?? (5 Replies)
hi,
i want to know cpu utilizatiion per process per cpu..for single processor also if multicore in linux ..to use these values in shell script to kill processes exceeding cpu utilization.ps (pcpu) command does not give exact values..top does not give persistant values..psstat,vmstat..does njot...

Hi Experts,
with the help of which command we can see the Number of cpu in a solaris solaris5.10.Also how we know the total disk & free disk space size in this system.
Kind regards

We are using linux server. We have below script running on the crontab and it send the alert if the cpu usage is above 90%.
My question is, the below script tells the CPU usage for one CPU or all CPU in the server?

Got two RHEL servers - one real and one virtual/cloud.
Both run apache web server.
When traffic is applied, CPU seems to go quite high on virtual one (20%) but real is not really affected. Worry is that a further increase in traffic will see a problem.
Experience of RHEL is limited. Whats... (2 Replies)
We have a single threaded application which is restricted by CPU usage even though there are multiple CPUs on the server, hence leading to significant performance issues. Is it possible to merge / combine multiple CPUs at OS level so it appear as a single CPU for the application? (6 Replies)

cpuid
CPUID(4) Linux Programmer's Manual CPUID(4)NAME
cpuid - x86 CPUID access device
DESCRIPTION
CPUID provides an interface for querying information about the x86 CPU.
This device is accessed by lseek (2) or pread (2) to the appropriate CPUID level and reading in chunks of 16 bytes. A larger read size
means multiple reads of consecutive levels.
The lower 32 bits of the file position is used as the incoming %eax, and the upper 32 bits of the file position as the incoming %ecx, the
latter intended for "counting" eax levels like eax=4.
This driver uses /dev/cpu/CPUNUM/cpuid, where CPUNUM is the minor number, and on an SMP box will direct the access to CPU CPUNUM as listed
in /proc/cpuinfo.
This file is protected so that it can only be read by the user root, or members of the group root.
NOTES
The CPUID instruction can be directly executed by a program using inline assembler. However this device allows convenient access to all
CPUs without changing process affinity.
Most of the information in cpuid is reported by the kernel in cooked form either in /proc/cpuinfo or through subdirectories in
/sys/devices/system/cpu. Direct CPUID access through this device should only be used in exceptional cases.
The cpuid driver is not auto-loaded. On modular kernels you might need to use the following command to load it explicitly before use:
$ modprobe cpuid
There is no support for CPUID functions that require additional input registers.
Very old x86 CPUs don't support CPUID.
