# <a id="resources"></a> Resources

The configuration file `config/resources.ini` contains information about data sources that can be referenced in other
configuration files. This allows you to manage all data sources at one central place, avoiding the need to edit several
different files, when the information about a data source changes.

## <a id="resources-configuration"></a> Configuration

Each section in `config/resources.ini` represents a data source with the section name being the identifier used to
reference this specific data source. Depending on the data source type, the sections define different directives.
The available data source types are *db*, *ldap*, *ssh* and *livestatus* which will described in detail in the following
paragraphs.
