This makes sense, however, I am still a bit confused. You are stating that in
Solaris 9 microstate accounting gets only updated when the lwp is transitions
from one state to another. So, if the process was idle for a long time (idle
since before microstate accounting was started by prstat -m ??) then I can see
that idle state counters might be out of whack. However, I would not expect
this to happen if the process had some activity since the prstat -m was
initiated. I am probably missing something.. Here is prstat-m output piped
throgh
gcars0d7% cat proc_prstat-m
#/bin/sh
nawk '
BEGIN {
} { t=$3+$4+$5+$6+$7+$8+$9+$10
if ((t < 90)||(t>110)) print $0, t
}
END{
}'
gcars0d7%
Look at the PID 1357 - it is always the same thread, esd/1 and it certainly had
some activity since prstat -m was initiated (USE/SYS/VCX/ICX are non-0).
If this is a known issue, does it impact idle/SLP counts only? Can I assume
that USR/SYS are correct? (in that case I can derive the idle from the rest)
gcars0d7% prstat -mL 10 | proc_prstat-m
