It would be nice to tackle dtrace separately as the work for others is already done (except for ARC) and they are waiting to be putback. I would rather not touch those if it is ok with you. status here. http://wikis.sun.com/display/WebStack/ApacheModules More over dtrace OSR has not been approved (and if the previous experience is any thing to go by it should take one or two months) | > 3.

I think you'll want to deliver a note to docs to at | least mention this module is being integrated, list the probes and a | pointer to more info. | > 5.1.

If I write a dtrace script using them can | you guarantee the probes won't change for the supported life of S11? As I mentioned above it is alpha stage, Nothing is stable, and the above relates only to 'configuration directives' which may cause an httpd.conf to become invalid after upgrade. | >From the above, it sounds like no.. at least until this matures a bit more? | List the exported probes in the exported interfaces. And from the | above, sounds like they are Volatile? This is more of a concern, perhaps we should wait until (either) it moves out of its alpha stage (or) one of us are willing to contribute to the developement (given that it is on solaris) and move it to stable land. | Not specific to this doc, just curious; do all the d scripts on | http://prefetch.net/projects/apache_modtrace/index.html | work ok with the integrated 2.2.6? Have not checked. Will check it once I am reasonably sure that dtrace will be integrated :) rahul -- 1. e4 _
