No backup of the Centreon Database ?
It will be a bit hard to recover your host. The problem is that to recover the graphs, even if you create a new host with the same name, the ID will be different in the DB.
The data for the graphs are stored in the centstorage DB. The table, where are stored the hosts and the services is `centstorage`.`index_data`. You can first try to check if your host is still there or not, with this SQL request :
Obviously, XXX is the exact Hostname of your firewall.
SELECT `centstorage`.`index_data`.`host_name`, `centstorage`.`index_data`.`id` FROM `centstorage`.`index_data` WHERE `centstorage`.`index_data`.`host_name` = "XXXXX"
If you have an entry (or more, depend of the number of services you had), you are lucky. If not, so it won't be possible (or i am not aware of a solution).
