We want these assumptions to be validated by a DTrace expert from Oracle. This validation is necessary to provide us confidence that DTrace can execute for a long period of time (in the order of weeks) along with our software, without introducing errors due to e.g. “dynamic variable drops”. In addition, we described a problem we experience with our DTrace script, for which we want to have support from you.
DTrace is designed to be reliable in one sense only: it won't consume so many resources as to kill production performance. This means that DTrace cannot be reliable in the sense of not dropping probe data. This is inescapable. Nico --
