Load Balancers
This page is for Device42 administrators who need to view and work with discovered F5 load balancers. Learn how to access load balancer resources, view resource maps, and understand the simplified Application Groups chart view.
Device42 SNMP discovery returns discovered load balancers as both devices and managed resources. Discovering F5 load balancers as managed resources provides additional details about the load balancers and their related resources, including resource maps that visually represent the relationships between load balancers and resources. This also simplifies the Application Groups chart view by placing the servers beneath a load balancer.
The recommended best practice for load balancer discovery is to first identify the devices using SNMP. This identifies the devices and associated resources. Next, perform a Windows/*nix discovery of the backend resources to get more detailed information. Once the devices are discovered, perform the API-based load balancer discovery to link the devices correctly.
Managed Resources Views
Discovered F5 load balancers are included in the Resources list. Navigate to Resources > All Resources from the Device42 menu to display the list page. See the Managed Resources documentation for more information.
Click the Vendor Resource Type dropdown and select F5 to filter the list for load balancer resources.
Click on a load balancer and use the right-hand panel to navigate between sections of the load balancer's details.
Click Resource Map on the top left of the load balancer details page to view the topography map for the resource. In the Tools & Breakdown section of the left-hand panel, you can view, add, highlight, and search items to include in the map according to their resource type.
The following image shows an example resource map for clustered load balancers.
The chart views for Application Groups are simpler and easier to understand. Navigate to Applications > Application Groups from the Device42 main menu to display the Application Groups list page.
Click on connection lines within the load balancer AG chart to open the Local View panel and view the communication details.
