Hello; By the way Solaris implemented some DTrace providers it looks like we need a scsi provider as a starting point for a iscsi provider, which in turn (plus the IP provider) is also a requirement to get NFSv4/NFSv3 providers. I suspect there may be some interest on having a scsi DTrace provider for it's own purposes, so JIC someone wants to try and at least for documentation purposes I will share some links I found on how it was done for OpenSolaris. The original commit in OpenSolaris seems to have been this: https://bitbucket.org/illumos/illumos-gate/commits/c4b38ec17f4eaacad8868141411d7b513910ad4a Then there is an interesting blog posting that accompanies it: "Adding a Dtrace provider to the kernel" https://blogs.oracle.com/chrisg/entry/adding_a_dtrace_provider_to And some general introductory documentation for reference: http://www.ibm.com/developerworks/aix/library/au-dtraceprobes.html https://wiki.freebsd.org/DTrace/HowToAddSDTProbes Hope someone finds this helpful, Pedro.
