This isn't quite what I lust for: Is it possible to get a *log* of allocation requests rather than aggregate sums or averages? The reason is so I can calculate the distribution of the data. For example: the kind of information I would like to have from kern_malloc for each invocation is: - time of the allocation - size - time spent in asleep - return value The same thing can be done with kern_free and from there the time the memory was used can be calculated. -Jeff To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
