some questions

[Rong-En Fan]

Hi,

I'm running Hobbit snapshot as of 9/3. I got few questions.

1. In what situations, I need to restart something to make
   configuration works? It's not clear to me that whether to
   restart foo after modifying bar.cfg.

2. According to FAQ, it says after a network test is failed, 
   it will retry every 1 minute until 30 minutes later. 
   Does the failure means red? If so, how about yellow?

3. Is is possible to postpone some network tests after the
   target machine is up for 5 minutes or so? The reason is that
   some daemon does not start up (yet) when the machine can 
   response ping. I don't want to get false alert for this.

   A possible workaround is to use badXXX tag in bb-hosts. But
   I wonder if there is a better way?

4. Is it possible to generate PDF reports? I saw it on demo site
   but it seems malfunction.
   Maybe I think I can generate one from the spreadsheet :-)

Thanks,
