Number of CPU cores 1

[ddrillich]

Good Day,

How can I tell how many cores the servers has?

Many thanks.

I only know this one:

grep "model name" /proc/cpuinfo

Thank you. I see the following -

[autonomy@sbkj2ksrchstp01 dan]$ grep "model name" /proc/cpuinfo
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz

prtconf

Khalid,

Sorry Dan! I'm coming from an AIX backgroud that's why!

Why don't you try dmidecode command? It has lots of nice HW listing.

Yet a more powerful tool is lshw which you will have to install! It has an option of creating a web page of your configuration!

Have a look here for more info:

I am not sure if you expected a return comment, but all you have to do above is count the cores and you are done...

The only other thing you can do to improve BadBigBen code is to add '| wc -l' at the end which will count the number of rows grep returns.

Or even shorter, just use grep -c.

I use "cat /proc/cpuinfo".

This shows you a lot more info on the cpu, and it gives a count on the processors starting at 0.

Sample output............
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 11
model name : Intel(R) Pentium(R) III CPU family 1266MHz
stepping : 1
cpu MHz : 1258.509
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse
bogomips : 2520.35

I do it the way happylinuxguy illustrated.

One other aside, depending on what level of "production" your server is in - the data on all the CPUs will usually appear in /var/log/syslog immediately after the system comes up from boot - there's usually a lot of interesting information in there right after boot.... So if it gets rebooted fairly often just check the log after.
