No bug here - we can absolutely use DTrace on MP systems, reliably and with confidence.
The script output shows some nasty outliers for a small percentage of the reads and writes happening on the server. Time to take a closer look at the IO subsystem. I'd start with "iostat -znx 1", and see what the queues look like, IO rates, and service times. I'd also have a look at the network. Download nicstat and run it (go to blogs.sun.com and search for "nicstat" - it's easy to find). What are you using for an on-disk file system? UFS or ZFS? /jim Marcelo Leal wrote: > Ok, but that is a bug, or should work like that? > We can not use dtrace on multiple processors systems? > Sorry, but i don't get it... > __ > Leal > [http://www.eall.com.br/blog] > _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
