See also the thread at http://lists.freebsd.org/pipermail/freebsd-current/2010-October/020564.html A suggestion from one of the followups: > I'd be very happy if all vmstat and iostat would get a command line > switch to suppress the "summary since last reboot" line. > This information may be useful for some cases but in other cases, like > creating performance data for monitoring systems like Icinga / Nagios > one has to remove the first line(s) manually. Adding this mode would solve the problem for non-interactive use of vmstat (in that overflow doesn't matter for the delta between two samples), but will leave the bogus data in the normal case. Maybe -q (quiet) could suppress the header and another -q could suppress also the first line? So vmstat -qq -w 1 -c 2 would provide just the one delta summary line after one second. (For reference, spare flags on vmstat and iostat seem to be b e g j l q r u v y) _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
