   Um ... there are LOTS of 'monitoring' apps for Linux
   at this point - just did a survey a couple of days
   ago. Most are serious OVER-kill. They also tend to
   record SO much shit that you'll never be able to find
   YOUR particular problem in the mess.

   Anyway, the "-b" param to 'top' did do the trick.
   Still not sure why evoking from the CL is so different
   from evoking via crontab - but that's how it is.
