Hi, I have been researching for a while but as i am stuck maybe someone could help me.
I am trying to finish the setup of centreon version 2.8.14. I continued somebody else work updating previous installation, that already had many hosts and services defined. The problem is that discovery has never worked, and still dont.
I can define network ranges to scan in Configuration > Centreon Discovery but when i try to scan them i get message Table 'centreon_storage.mod_discovery_config' doesn't exist.
In the process of upgrading, in the web part there was a part when i get the message updating database. I left it for 24 hours, but nothing happened. The "next" button, was always available, and i clicked it to end the upgrading, but the results were those explained.
I tried also the following:
yum install centreon-plugin-Discovery-Nmap
Loaded plugins: fastestmirror
Setting up Install Process
Loading mirror speeds from cached hostfile
* base: mirror.centos.org
* epel: mirror.upb.edu.co
* extras: mirror.centos.org
* updates: mirror.centos.org
Package centreon-plugin-Discovery-Nmap-20170807-1.el6.noarch already installed and latest version
Nothing to do

Any ideas are very welcome
