The article seems to cut our a bit > early leaving me to do a great deal of guesswork. I'd set MaxBytes[load] at 100, but AbsMax at an outrageous number (100000 or whatever). That way you'll get numbers >100% when your loadavg goes above 1.00. Set MaxBytes[swap] at whatever your swap size is. -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
