如何查看服务器上有多少个CPU

hotmanhh

从DBA的角度来说，有时候需要考虑CPU的利用率的问题。那个服务器上有多少个CPU和利用率情况如何就是要考虑的问题了。
查看有多少个CPU：
#psrinfo -v
结果显示如下：
Status of processor 0 as of: 07/28/05 11:24:23
  Processor has been on-line since 05/27/05 17:43:26.
  The sparcv9 processor operates at 900 MHz,
        and has a sparcv9 floating point processor.
Status of processor 1 as of: 07/28/05 11:24:23
  Processor has been on-line since 05/27/05 17:43:26.
  The sparcv9 processor operates at 900 MHz,
        and has a sparcv9 floating point processor.
Status of processor 2 as of: 07/28/05 11:24:23
  Processor has been on-line since 05/27/05 17:43:26.
