Turning on Application Discovery
To turn on Enterprise Application Mapping, simply check the “Discover Applications” checkbox while configuring your discovery job. If you are new to discovery, see Getting Started with Auto-Discovery to get acquainted. If you would like to discover config files, they can also be imported into Device42; select the “Store Application Components 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 that associates all Oracle Database services together on that machine. The Auto-Discovery Application will also find the service-to-service connections so you could, for example, see that your Apache service on Prod-Server1 is directly dependent on the MySQL service running on Prod-Database3.
Importing Config Files
If the option to store config files is selected in your Auto-discovery options [pictured above], configuration file data will be imported to the Application Components details as well.
Viewing Application Dependencies
To see auto-discovered application dependencies, go to Apps>Application Components, and you will see any Application Components that were 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. You’ll also see any services that have been associated with the application component. From here, you can also edit the application to assign responsible and/or 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 the 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 web-servers, database servers, etc. To view this information, while hovering over one of the services click “Details”.
