When we cat/proc/cpuinfo, CPUs with the same core ID are the same core hyper-threading, and CPUs with the same physical IDs are threads or cores encapsulated by the same CPU.

Because of all the original, we may need to look at the Linux Server board model, CPU model, memory size, the number of memory lines. Because the server uses a RAID card, the usual view of the hard drive information can not be used, to be added back later!

Recent re-statistics of some of the server's basic information, initially wanted to use the Excle form. But since Zabbix has the function of asset management, it is better to use this function directly.Do as you say.
