Monitoring individual processor performance form Tru64UNIX v4
Hi,
Is it possible to monitor the individual processor usage in a multi processor environment with Tru64UNIX v4 using utilities provided in the standard operating system installation? I believe on other versions of UNIX there is a utility called cpustat.
Thanks
Andrew

Re: Monitoring individual processor performance form Tru64UNIX v4
Andrew,
sched_stat -u can show you the familiar user, system, wait, idle values on a per cpu basis. Other options give useful stuff about load balance and scheduling.
On more recent releases its part of the base o/s, but on older releases you'll need to run the copy that ships with sys_check, for example /usr/opt/SYSCHECK145/lbin/sched_stat.
Or, you could use collect. It can show agregated cpu stats, and the individual cpu usage. But it doesn't give the detail that sched_stat does.
Or, if you have the optional System V Environment package installed, you could use sar (it lives in /usr/opt/svr4/usr/bin/sar). Sar -P can report per cpu values as well as the usual agregate value.
