Nope.

Yep. But, do you really want to monitor everything and recreate the
web pages once a minute? There can be unintended consequences to
this. To quote Sean, this can:

  * Increase the load on the BBNET/BBDISPLAY machines by a factor of 5
  * Could page you *every minute* for a problem
  * Could be too short for the BBNET process to complete all the
    tests on your network (especially if you're testing 100 devices,
    if only 3 were down, you'd start getting "bbrun longer than bbsleep"
    messages (3 down @ 20 second delay each = 60 seconds).

Often, it is possible to achieve the kind of responsiveness that you
need without resorting to this. If you let the list know why the default
cycle time is not suitable for you, someone might be able to provide
an alternative solution.

Cheers, Phil.
