GOAL:

How to determine how many CPUs you have in SCO UNIX

GOAL:

How to see the average CPU utilization for each CPU

FACT(s) (Environment):

SCO OpenServer

FIX:

Run the following command to gather information about the machine:


$ uname -X
  System = SCO_SV
  Node = servername
  Release = 3.2v5.0.0
  KernelID = 95/08/08
  Machine = Pentium
  BusType = EISA
  Serial = 4DA004009
  Users = 30-user
  OEM# = 0
  Origin# = 1
  NumCPU = 2

The last entry states that this machine is running with 2 CPU's.

Run the following command:

  mpsar 2 5

mpsar combines the data of all the CPUs, 2 is the interval in seconds and 5 the number of times that mpsar information is displayed.

$ mpsar 2 5


  SCO_SV servername 3.2v5.0.0 Pentium    04/15/99

  16:50:50    %usr    %sys    %wio   %idle
  16:50:52       0      50       0      50
  16:50:54       0      50       0      50
  16:50:56       0      50       0      50
  16:50:58       0      50       2      47
  16:51:00       0      50       0      50

  Average        0      50       0      49

Use another command to see the information for each CPU

cpusar -u -P1 2 5  (where -P1 is the first system default CPU)

$ cpusar -P1 2 5


  SCO_SV servername 3.2v5.0.0 Pentium    04/15/99

  17:04:27    %usr    %sys    %wio   %idle
  17:04:29       0       0       0     100
  17:04:31       0       1       1      98
  17:04:33       0       0       0     100
  17:04:35       0       0       0     100
  17:04:37       0       0       0     100

  Average        0       0       0      99

cpusar -P2 2 5  (where -P2 is the second system default CPU)

$ cpusar -P2 2 5


  SCO_SV servername 3.2v5.0.0 Pentium    04/15/99

  17:05:11    %usr    %sys    %wio   %idle
  17:05:13       0     100       0       0
  17:05:15       0     100       0       0
  17:05:17       0     100       0       0
  17:05:19       0     100       0       0
  17:05:21       0     100       0       0

  Average        0     100       0       0

Use sar in single processor systems.
Use cpusar and mpsar on multiprocessor machines.
