Topology Explorer

The topology explorer provides visualization of resources in your infrastructure, their relationships, and availability, to help troubleshoot network-related issues.

Prerequisite

A user should have Device Manage and Device View permissions.

HostName/IP Address-based topology

View the topology of a specific resource by providing the hostname or IP address.

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.

   

   
   
3. In the drop-down list, select HostName/IP Address, which is the default selection.
   Note: Select the required network device from the list to see the topology view.
4. Select the resource, and check the topology layout. The topology explorer is displayed with the base resource you selected and its neighbors including the connections based on Depth level.
   Note: following are the different Depth Levels (Supported Depth levels - 1,2,3,4,5)
   
   Example
   
   Depth level 1 : (Source Device)

Depth Level 3 :

Source

Availability of source is based on the infrastructure. Source has five availability state, which are as follows:

• Up
• Down
• Undefined
• Unknown
• Default

Link

Link has their own source interface and target interface. Availability status for links will be shown based on source interface. Link had three availability state, which are as follows:

• All links generated from the source node (target links) are represented with dotted lines, when the source is down.
• The default colour for links is Blue.

5. Click anywhere on a link (on a line) to view the Source and Target interface details.

Following is the information with description:

6. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

Refresh Page

The page is refreshed based on the selected frequency:

• 5 Mins
• 10 Mins
• 15 Mins
• 30 Mins
• 60 Mins
  Note: By default 10 min is selected.

6. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

Azure topology

After integrating Azure cloud services, use topology explorer to view the resource service dependencies.

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.
3. In the drop-down list, select Azure.
4. In the Select Account and Select Location drop-down lists, select the Azure account and location.
5. In the services drop-down list, select the service, which displays the Azure topology map for the selected account. If you want to view the topology of an Azure instance, select the instance from the Resource drop-down menu.
6. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

Google topology

6. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

Hypervisor topology

The hypervisor environment consists of KVMs, vCenter, and ESXi hosts. After onboarding these resources, you can view the topology map containing the resources, including dependent hosts.

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.
3. In the drop-down list, select the entities KVM, vCenter, or ESXi Host.
4. In the Select Resource drop-down menu, select the resource to display the topology.
5. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

Kubernetes topology

After onboarding Kubernetes and installing the agent on the Kubernetes resource, use topology explorer to view the Kubernetes topology nodes and containers.

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.
3. In the drop-down list, select Kubernetes.
4. In the Select Resource drop-down menu, select the required resource.

8. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

Resource group topology

Resource group topology groups all devices in a single location, where you can see the complete network topology map. Every resource has a connection, if there is no connection between those two resources, it will display as an island.

Business Use case: Let us assume that one node contains twenty network devices, which are connected to thirty servers, for those twenty network devices, the availability of the network device and the link node status of the other end connected devices is displayed.

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.

   Note: The Depth option is unavailable for the Resource Group Topology.
6. Click a resource to view more information about the resource, including resource availability status. Click the external link icon beside the resource name to view the resource details page.

   

Limitations

• Resource group topology supports up to 250 devices.

Resource UUID

View the topology of a specific resource by providing the Resource UUID. The filter facilitates the topology map for the SDK adapter with the Resource UUID. You can navigate to the Resource UUID by the following methods

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.
3. In the drop-down list, select the entities Resource UUID.
4. In the Enter Resource UUID, paste the Resource UUID.
