Hello, I have some serious issue. Sometimes something happens and my disk usage performance find its limit quickly. I follow with gstat and iostat -xw1, and everything usually happens just fine, with %b around 20 and 0 to 1 pending i/o request. Suddely I get 30, 40 pending requests and %b is always on 100% (or more than this).
fstat and lsof gives me no hint, because the type of programs as well as the amount of 'em is just the same. How can I find the PID which is hammering my disk? Is there an "iotop" or "disktop" tool or something alike? Its a mail server. I have pop3, imap, I also have maildrop and sometimes, httpd, working around the busiest mount point. I have also started AUDIT, however all I can get are the top PIDs which issue read/write requests. Not the requests which take longer to perform (the busiest ones), or should I look for some special audit class or event other than open, read and write? Thank you in advance. -- =========== Eduardo Meyer pessoal: [EMAIL PROTECTED] profissional: [EMAIL PROTECTED] _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
