	Thanks for the tips Henrik and Frédéric, I'll check out bbgen and Hobbit now.

BB's shell scripts don't perform at all well when you move into monitoring 
several hundred boxes.

I had the same problem and ended up writing tools to solve it:

* bbgen - an add-on to BB that replaces the web-generator and network-test
  shell scripts with tools written in C.

* Hobbit - replaces BB completely, the successor to bbgen.


Both available at http://hobbitmon.sourceforge.net/ - GPL licensed, so
they can be used free of charge.

Henrik
