There are already kernel counters for most (probably all) of the things sar would need to measure. The only problem is writing sar, sa1, sa2, and sadc. If you don't mind the GPL, the Linux systat package includes an implementation of sar. In 1999, SCO promised to release their source under MPL, but never did. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
