Is it possible to use DTrace to display the number of arguments and their types for userland or kernel functions that are not explicitly instrumented or documented by their authors? We''re talking about functions provided by Veritas VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or

We have a 32 GB RAM server running about 14 zones. There are multiple databases, application servers, web servers, and ftp servers running in the various zones.

on Solaris 10 5.10 Generic_118822-23 sun4v sparc SUNW,Sun-Fire-T200 I run #iostat -xn 5 to monitor the IO statistics on SF T2000 server. The system also have a heavy IO load, for some reason iostat donot refresh (no any update). It seems like iostat is calling pause() and stucked there. Also my HBA driver''s interrupt stack trace indicates there is a lot of swtch(), the overall IOPS

Hi i''m trying to write my first dtrace script apparently i bit off a bit more than i can chew, i want to track io over sockets, i found your socketsize.d that gave me how to track writes, but i''m at a loss how to track reads, frankly i don''t see how your write tracker works because it uses a probe in a function that only takes two arguments but you grab size of write
