How do I find the speed and number of CPUs

[jlstitt]

How can I quickly find out the number and speed of processors in a box I'm telneted into. And how do I find out what sort of a load they're under?

Hi,

You can get info via 'sysinfo', e.g.

SUNW,Ultra-80
cpu0 is a "450 MHz SUNW,UltraSPARC-II" CPU
cpu1 is a "450 MHz SUNW,UltraSPARC-II" CPU
cpu2 is a "450 MHz SUNW,UltraSPARC-II" CPU
cpu3 is a "450 MHz SUNW,UltraSPARC-II" CPU

Run 'prstat' to see the load on a process basis, or use the
the 'share-ware 'top'. To sample the CPU load use 'iostat'

iostat 3 10
tty sd0 sd1 nfs2 nfs3 cpu
tin tout kps tps serv kps tps serv kps tps serv kps tps serv us sy wt id
0 37 660 18 13 623 49 7 0 0 5 0 0 9 19 7 8 66
0 78 572 13 13 858 92 6 0 0 0 0 0 0 15 5 14 66
0 27 768 16 14 878 90 6 0 0 0 0 0 0 16 6 14 63

cheers,

Thanks much... I tried to find "sysinfo" but it didn't appear to be a command or a file in /etc ... The box is running Solaris 8 on a Sun 280 (I think)

Hi,

/usr/platform/`uname -m`/sbin/prtdiag -v

also give you lot of information

Try psrinfo. That's what it's for...

$ psrinfo -v
Status of processor 0 as of: 11/08/02 16:49:11
Processor has been on-line since 08/17/02 22:22:41.
The sparc processor operates at 400 MHz,
and has a sparc floating point processor.
Status of processor 1 as of: 11/08/02 16:49:11
Processor has been on-line since 08/17/02 22:22:45.
The sparc processor operates at 400 MHz,
and has a sparc floating point processor.
Status of processor 4 as of: 11/08/02 16:49:11
Processor has been on-line since 08/17/02 22:22:45.
The sparc processor operates at 400 MHz,
and has a sparc floating point processor.
Status of processor 5 as of: 11/08/02 16:49:11
Processor has been on-line since 08/17/02 22:22:45.
The sparc processor operates at 400 MHz,
and has a sparc floating point processor.

For the load, try top. It may be /usr/local/bin/top, or elsewhere. You may need to "find" it, but it gives you some good info on the load and who's creating the load...

$ which top
/usr/bin/top
$ top

I like mpstat for the CPU load I tried to remain child-like, all I acheived was childish.
