Forgive me, where do I find 'interstat' ? Also, where can I get Sun::Solaris::Kstat for prustat?

Based on a few hunches, try these: - interstat 1 look for a network driver burning CPU - pidpersec.d from the DTraceToolkit (or "sar -c 1 100" if DTrace won't behave) look for lots of short lived processes - "procsystime -coT" from the DTraceToolkit look for frequent syscalls burning CPU time - dtrace -n 'profile-101 { @[stack(5)] = count(); }' (this has a slower profile rate than hotuser) look for hot kernel stacks Brendan -- Brendan [CA, USA] _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
