From the iostat(8) man page: SEE ALSO fstat(1), netstat(1), nfsstat(1), ps(1), systat(1), pstat(8), vmstat(8) What information are you looking for specifically? Have a look at systat(1). It presents the activity on your system nicely, breaking it down into several descriptive categories which are documented in the man page. Try this: $ systat -io Hope that helps, -brian -- Brian O'Shea boshea@ricochet.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
