answers to your questions.

1 - All graphs

2 - All devices (network switches/ firewall/ windows servers)

3 - Not 100% sure when it started but it seems like a week ago or about when I did an SVN update. Don't know how to use svn much so no idea on how to rollback.

4 - Debug log hasn't been showing any new data since 12/18/14. I actually asked this on a separate email and no one answered. 

The only graphs that are showing up fine are the smokeping ones.

Sorry if it seems like your beating answer out of me but i am for one not a Linux expert and just getting into linux full time. A lot of the simple logs and debugging things I don't know how to do because of this (more experience in windows/networking). Also there is lack of documentation and use of observium so googling doesn't always turn up an answer.

Hope you can help.
