Hi,
I wrote a simple recorder script, similar with mpstat, done in Perl,
using Sun::Solaris::Kstat. The utility is found:
http://www.nbl.fi/~nbl97/solaris/perf/sdr_bin/cpurec062. Based on
Brendan's K9Toolkit, the script uses kstat to extract for each cpu
found on the system the following information:
* timestamp: seconds since Epoch
* Xcalls: rate of multiprocessor cross calls
* Intr: rate of intrerrupts
* iThr: rate of interrupts threads
* Csw: rate of context switches
* Icsw: rate of involuntary context switches
* Migr: rate of migrations
* Smtx: rate of kernel mutexes
* Syscalls: rate of system calls
* User: percentage of time spent in user mode
* Sys: percentage of time spent in sys mode
* Idle: percentage of time spent in idle mode
This works fine except from time to time Im able to see
situations like: user+sys+idle != 100 . Is this my bad in converting
something or simple these are the values coming from kstat !?
Any ideas ?
Many thanks,
stefan
