Nagviz database error


I had to restart our Nagios server after a power outage this weekend. When it came back up, Nagviz said that all of my hosts did not exist–essentially, it couldn’t find the database. I checked and the ndo2db service is running, mysql is running (and I can browse the tables using both MySQL Tools and Webmin), and I can see the maps themselves–just the hosts are not found. I did try deleting and recreating a host to see if that would make a difference, with no luck.

Any help at all would be appreciated. If you need any more information about our server, please let me know. Thanks so much!
