Yes, but I have the impression (of which I wouldn't mind being disabused) that that approach would perturb the systems being measured somewhat more than using time(1) for the selected processes and sysctl(8) to get information on the overall system status. Note that I'm interested in measuring rather specific instantiations of certain commands/processes -- not the bulk of them. I believe that makes a salient difference. Peace, david --=20 David H.
