It would be better if you could separate the code for the configuration
data from the status data. A better place to hook in for status data
(including acknowledgement and downtime) is the new NEB module and its
use as demonstrated by the nagios-db project.
With the config data going into a database, it important to verify
consistency of the data with respect to nagios's data structures. yes
Nagios does that on startup, but the UI to manage the data entry should
also do verification.
