Topology Explorer

The topology explorer provides a topological view of the resources in your infrastructure to help troubleshoot network-related issues.

Before using topology explorer, make sure you check the following setup items:

• Enable user Device Manage and Device View permissions.
• Enable CDP and LLDP on network resources as described in the vendor resource documentation.
• Select gateway protocol when configuring the discovery profile.
• Include IP addresses in the same discovery profile(Scan IP Range) or Seed IP discovery type to avoid duplicate topology maps.

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 neighbours 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 a resource to view more detailed information about the resource, you can view the detailed information as shown below:

Refresh Page

You can configure how frequently the discovery action should trigger, based on the selected frequency, the information will be updated. Select frequence to add one of the following patterns:

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

Application topology

View the topology for applications running in your environment. This requires the agent to be installed on the resource running the application. Also, make sure Application Discovery & Dependency Mapping is enabled for the client:

1. Click All Clients and select a client.
2. Go to Infrastructure > Topology.
3. In the drop-down list, select Applications.
4. Select the Depth and topology layout. the application topology is displayed, including inbound and outbound connections, number of alerts, incidents, and patches missing on an application.

AWS topology

After integrating AWS 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 AWS.
4. In the Select Account and Select Location drop-down lists, select the AWS account and location.
5. In the services drop-down list, select the service, which displays the AWS topology map of the selected account. If you want to view the topology of an AWS instance, select the instance from the Resource drop-down menu.
6. Click a resource to view more detailed information about the resource, including resource availability status and the number of alerts triggered on the resource.

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.

Google topology

After integrating Google 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 Google.
4. In the Select Account and Select Location drop-down lists, select the Google account and location.
5. In the services drop-down list, select the service, which displays the Google topology map for the selected account. If you want to view the topology of a Google instance, select the instance from the Resource drop-down menu.

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.

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.
5. Select Nodes or Containers from the drop-down menu.
6. Select the Depth and topology layout to display the Kubernetes topology.
7. Click the resource to view more detailed information. The Summary pane displays the inbound connections, outbound connections, and applications running on the resource.

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.
3. In the drop-down list, select Resource Group.
4. In the Select Resource drop-down menu, select the required resource.
5. The topology explorer is displayed with the base resource you selected and its neighbours including the connections.
   Note: The Depth option is unavailable for the Resource Group Topology.

Limitations

• Resource group topology supports upto 250 devices.
