   I'll match your sigh and add some curse-words.  One of our fileservers:

     date:   Mon May 18 09:03:09 EDT 2009
     uname:  FreeBSD 4.9-RELEASE #0
     uptime: 9:03AM up 732 days, 11:36, 0 users
   Here's part of the output from "vmstat -s".  I like the name lookups:

     1644362297 cpu context switches
     1093285479 device interrupts
     1789304683 software interrupts
     3124531993 traps
     3752497578 system calls
     2443779332 pages examined by the page daemon
     1221349376 copy-on-write faults
     3820203746 zero fill pages zeroed
     1406714307 zero fill pages prezeroed
     1893555896 total VM faults taken
     3652052770 pages affected by  fork()
     2853118974 pages freed by exiting processes
      -92074736 total name lookups
              cache hits (449% pos + -1238% neg) system -1854% per-directory
              deletions -18%, falsehits 0%, toolong 0%

   Then our halfwit UPS decided to have a hissyfit and knock down this
   system plus four others.  Fortunately, our backup server stayed up:

     date:   Wed May 27 16:45:10 EDT 2009
     uname:  FreeBSD 6.1-RELEASE #0
     uptime: 4:44PM up 595 days,  3:09, 1 user
