After customizing Cacti with some plugin, I thought it would be enough for our needs.
Actually, it turns out I have to install a Nagios (need to perform checks using customized commands) and I discovered Icinga, a fork from Nagios.
I used to work with Nagios in the past, so I decide to try Icinga (2 birds 1 stone).
So I installed Icinga2 with Icingaweb2 (which is still in beta, but most features are already working).
What I noticed during the setup :
- Icinga2 installation guide is complete.
- Icingaweb 2 installation guide still need to be completed.
For example, you need to know that icingaweb 2 need its own database for authentication (if database option is selected). Just compared the icinga2 sql schema and the icingaweb 2 sql schema (located in icingaweb2/etc/schema/), and you will see the tables are different.
And during the web setup, the user wasn't created. So I created a dedicated db for icingaweb2 and I imported the sql schema to the database (mysql -u root -p icingaweb_db < /icingaweb2/etc/schema/mysql.sql).
I installed the monitoring-plugins and set the define the path on one Icinga config file.
Finally, it works.

Hi, I am trying to get Icingaweb2 working on my CentOS 7 server. When I tried enabling the "Monitoring" module from web console, menu items on left panel suddenly changed into "Icinga\Exception\ConfigurationError in /usr/share/icingaweb2/modules/monitoring/library/Monitoring/Backend/MonitoringBackend.php:181 with message: No backend has been configured". However, when I tried clicking "Backends"to add one, it shows following:
#0 /usr/share/icingaweb2/modules/monitoring/library/Monitoring/Backend/MonitoringBackend.php(78): Icinga\Module\Monitoring\Backend\MonitoringBackend::loadConfig(NULL)
#1 /usr/share/icingaweb2/modules/monitoring/library/Monitoring/Backend/MonitoringBackend.php(219): Icinga\Module\Monitoring\Backend\MonitoringBackend::instance(NULL)

Can you help? Thanks.
Hi Michael,
Have you check your connection to your database?
