This has been covered before. I would love to see dtrace(and zfs) in OpenBSD to, but there are licensing issues regarding the CDDL. I *think* (but might be wrong) the main problem is that this kind of stuff needs to be kernelized, and only BSD licensed code can be there (Am I correct?). However I believe the LKM (loadable kernel modules) framework still works for OpenBSD, so perhaps you could make a port that makes a module??? I think the nearest you will get to dtrace on OpenBSD is ktrace/kdump, althought these tools are more like truss than dtrace. All of Suns new dtrace/zfs code is in FreeBSD, perhaps this is better for you? -- Best Regards Edd --------------------------------------------------- http://students.dec.bournemouth.ac.uk/ebarrett
