Turning on Application Discovery
To turn on Enterprise Application Mapping in the D42 Auto-Discovery application simply check the “Discover Applications” checkbox. Also if you would like any discovered config files imported into Device42 as well select the “Store Config Files” checkbox. When auto-discovery is run, Application Components will be created based on related services on a server. For instance, a server with Oracle Database running will have a component created associated all Oracle Database services together on that machine. the Auto-Discovery Application will also find service-to-service connections so you could see that your Apache service on Production Server 1 is directly dependent on the MySQL service running on Production Database 3.
Importing Config Files
If the option to store config file is selected in the Auto-Discovery application, config data will be imported to the Application Components details as well.
Viewing Application Dependencies
To see auto-discovered application dependencies, go to Software>Application Components, you will see any Application Components auto-discovered.
A full list of currently supported applications is available at Application Dependency Mapping Supported Applications.
When you view the details page for an application component, you will see the device it was discovered on, as well as any other application components that it depends on, as well as any associated services that have been associated with the application component. From here you can also edit the application to associate responsible and affected departments, describe what’s impacted by downtime, and edit any custom fields.
Application Impact Charts
With Enterprise Application Mapping, your impact charts allow for an enhanced view of relationships between devices, services and applications. Viewing a device impact chart will now show you the application components that are on it, as well as the services, listening ports, and service connections between devices.

From this view you can also see discovered configuration information for webservers, database servers, etc. To view this information, while hovering over one of the services click “Details”.
