Configuration

If Icinga Web has been installed but not yet set up, please visit Icinga Web and follow the web-based setup wizard. For Icinga Web setups already running, log in to Icinga Web with a privileged user and follow the steps below to configure Icinga DB Web:

If you have previously used the monitoring module, there is an option to migrate some settings.

Database Configuration

Connection configuration for the database to which Icinga DB synchronizes monitoring data.

1. Create a new resource for the Icinga DB database via the Configuration → Application → Resources menu.

2. Configure the resource you just created as the database connection for the Icinga DB Web module using the Configuration → Modules → icingadb → Database menu.

Redis® Configuration

Connection configuration for the Redis® server where Icinga 2 writes check results. This data is used to display the latest state information in Icinga DB Web.

1. Configure the connection to the Redis® server through the Configuration → Modules → icingadb → Redis menu.

Info

If you are running a high-availability Icinga 2 setup, also configure the secondary master’s Redis® connection details. Icinga DB Web then uses this connection if the primary one is not available.

Command Transport Configuration

In order to acknowledge problems, force checks, schedule downtimes, etc., Icinga DB Web needs access to the Icinga 2 API. For this you need an ApiUser object with at least the following permissions on the Icinga 2 side:

• actions/*
• objects/query/*
• objects/modify/*
• status/query

Tip

For single-node setups it is recommended to manage API credentials in the /etc/icinga2/conf.d/api-users.conf file. If you are running a high-availability Icinga 2 setup, please manage the credentials in the master zone.

1. Please add the following Icinga 2 configuration and change the password accordingly:

   object ApiUser "icingadb-web" {
       password = "CHANGEME"
       permissions = [ "actions/*", "objects/modify/*", "objects/query/*", "status/query" ]
   }
   

2. Restart Icinga 2 for these changes to take effect.
3. Then configure a command transport for Icinga DB Web using the credentials you just created via the Configuration → Modules → icingadb → Command Transports menu.

Info

If you are running a high-availability Icinga 2 setup, also configure the secondary master’s API command transport. Icinga DB Web then uses this transport if the primary one is not available.

General Configuration

You can adjust some default values of options users have while interacting with particular dialogs in the UI. (e.g. While acknowledging a problem) These options can not be adjusted in the UI directly, but have to be set in the configuration file /etc/icingaweb2/modules/icingadb/config.ini.
