grep 'core id' /proc/cpuinfo | sort -u | wc -l

3. Check the number of threads
grep 'processor' /proc/cpuinfo | sort -u | wc -l

example :

[root@test1 ~]# grep 'physical id' /proc/cpuinfo | sort -u  | wc -l
[root@test1 ~]# grep 'core id' /proc/cpuinfo | sort -u | wc -l
[root@test1 ~]# grep 'processor' /proc/cpuinfo | sort -u | wc -l
[root@test1 ~]# 

This server has 2 individual CPU, Every CPU Yes 8 Core , Each core 4 Threads , common 32 Threads .
adopt dmidecode You can see cpu model , You can also find this according to the model CPU Specific parameters .

[root@qtrac1 ~]# dmidecode -s processor-version
