You can use net-snmp and mrtg to graph disk stats. I suggest applying the patch at http://sourceforge.net/tracker/index.php?func=detail&aid=1085243&group_id=12694&atid=312694 so you get 64-bit counters (32-bit counters roll over too fast to be useful): $ snmptable -v2c localhost diskiotable SNMP table: enterprises.ucdavis.ucdExperimental.ucdDiskIOMIB.diskIOTable diskIOIndex diskIODevice diskIONRead diskIONWritten diskIOReads diskIOWrites diskIONReadX diskIONWrittenX diskIOLA1 diskIOLA5 diskIOLA15 1 da0 3682573440 4134971392 7734458 71468595 68107082880 828768692224 1794 398 138 2 cd0 24 0 3 0 24 0 0 0 0 3 cd1 911237260 0 13932 0 911237260 0 0 0 0 4 pass0 1622 24 40 1 1622 24 0 0 0 5 pass1 0 0 0 0 0 0 0 0 0 6 pass2 57676 2710198624 3302 42848 57676 2710198624 0 0 0 If you graph diskIONReadX and diskIONWrittenX over time, you'll get a nice graph of throughput. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
